Black Diamond Color and Treatment

Sandra Bullock flaunting the black diamond studs or Kim Kardashian getting a black diamond engagement ring from Kanye; Black diamonds are ‘The Thing’ in the fashion world.  Coveted for their rich black color and enigmatic sheen, like that of a shiny black Rolls-Royce, not all the mined black diamonds are black and as beautiful. Though naturally black untreated diamonds do exist but they are extremely rare therefore very expensive; as a result the not so perfect real diamonds are treated to alter the color, remove defects and improve the quality.

Most black diamond jewelry sold today has treated black diamonds. Diamond color depends on the quantity and type of inclusions – graphite, pyrite or hematite. The color of the natural black diamonds may range from dull gray to almost colorless to milky to brown or “olive” green. These diamonds are therefore treated to obtain the black color.

Treatment Facts-

  • Most black diamonds available in the market have been treated.
  • Treated black diamonds are more affordable than their natural untreated counterparts.
  • Treatment is used to improve the diamond color, alter the diamond color, remove factures and other imperfections.
  • To know if the black diamond is treated simply view it under a strong maglite or fiber-optic light the edges will appear deep brown rather than black.
  • A 1.00 carat natural untreated-unheated AAA quality black diamond will cost between $2000-$2500 and a treated black diamond will cost around $900-$1300.

The most common treatments for black diamonds are Heat Treatment  and Irradiation.

Heat Treatment –

Polished or rough diamonds under this treatment is exposed to very high temperatures, almost burning them to change the color. The treatment is permanent and considered natural. Usually yellow or heavily included grey diamonds are heat treated that changes their color to almost black dark green. The diamond looks black but when viewed under the artificial light it appears green at the corners. This treatment is also used to remove the light brown or yellowish tint from the colorless diamonds. Depending on diamond the treatment is used either to enhance or alter the color. Heating can render the diamond brittle so should be protected from any harsh blows.

Irradiation – The process is used to physically alter the crystal lattice of the diamond to change its diamond color. The diamond is blasted with high-energy electron or neutron particles that relocate the carbon atoms thus altering the color. Usually blue, green and black diamonds are irradiated. The gemological labs can detect the treatment. Irradiation is often followed by heating to obtain the perfect color.

Irradiation Facts –

  • The amount of radiation in diamonds/gems is extremely small and absolutely safe to wear. Even the most irradiated Blue Topaz is absolutely safe. Read more
  • No proof found of irradiated diamonds/gems causing any health hazard or cancer.
  • The radiation continues to decay over the period of time, so the dose rate goes down.
  • Irrdaiation is only done to change the color of the stone, it does affect the clarity of the diamond.
  • Irradiated diamonds are 100% natural and real, the process only changes their appearance.
  • Diamonds are exposed to irradiation while still under the earth, which means all diamonds are irradiated.
  • Exposure to extreme heat may affect the color of the diamond though will not render it colorless in any way.
  • Irradiation was first done by a British scientist Sir William Crookes in 1904.

Treated black diamonds are more affordable and equally stunning as the untreated natural black diamonds. A treated black diamond engagement ring can cost you three-times less than the cost of a White Diamond engagement ring of the same carat. Black diamond studs, black diamond pendant or a black diamond stackable ring, make a pick.

How to buy the Perfect Black Diamond?

The popularity of black diamond jewelry especially engagement rings has surpassed all colored diamonds. Beautiful, stylish and affordable, black diamonds carry a unique appeal. However there is not much information available regarding these gems. We have in this article endeavor to give you correct information that can help one choose the right diamond.

Quality is King – AAA or AAA+ quality black diamonds are the best. However, while buying black diamonds do not pick a diamond below AA quality. Make sure that you properly check all the quality parameters- Clarity, Cut, Color and Carat. Clarity is the most important aspect of black diamond quality; however the quality standards of black diamonds are very different. In black diamonds only the table and crown clarity is taken into consideration. Though inclusions are typical to black diamonds but since the diamonds are opaque the inclusions below the girdle do not affect the beauty of the diamond. So make sure that the face of the diamond is smooth and does not have any inclusions, pits, white spots, cracks etc.

The color of the black diamonds is not usually pitch black rather dark metallic black, dark greenish black or deep brownish black. Rich dark colored diamonds are more sought after; however in black diamonds consistency of the color is equally important. So a good quality diamond will have a rich blackish color which spreads evenly across the stone. Dull, patchy, grayish diamonds are not good.

Black Diamond Color and Treatment

The symmetry of the diamond shape in blacks is more important than the cut. The cut refers to the number of facets on the diamond but in blacks there are no set standards for black diamonds. Shape refers is the overall form of the diamond, which should be proportionate. Though asymmetric and other geometric shapes are quiet famous in blacks but when buying standard shapes like round, oval or heart then proportions become crucial.

Treated or Not Treated that is the Question…Well the answer would probably be a Treated Diamond. The reason being, that naturally occurring AAA quality black diamonds are very very rare. This rarity not only makes them difficult to find but also makes them very expensive. To address this scarcity the suppliers started treating the not so perfect or dull or different colored diamonds to get the desired color. Today maximum number of black diamonds available in the market is treated. However, there is nothing wrong about treated diamonds; they are absolutely natural and real diamonds that have been treated to improve the color. In simple words by treating diamonds humans finish the unfinished work of mother earth. Treating gemstones or diamonds is a very common and ancient phenomenon. Emeralds, rubies, tanzanite, sapphire most gemstones are treated to either enhance the color or improve the clarity.

Buyers Tips

  • It is advisable to always buy a certified black diamond.
  • Shop online you will get more options at lesser rates. Choose a reputed jewelry portal. Ask for complete details, videos and close-ups of the diamonds and thoroughly inspect the diamond.
  • In case of natural black diamonds ask for GIA certified diamonds. GIA does not evaluate treated diamonds.
  • Choose AAA or at least AA quality black diamonds, anything below AA quality will have visible flaws on the diamond table.
  • Check the location of the flaw or inclusion. Sometimes even AA diamonds with minor flaws make a good purchase. Occasionally a diamond is graded AA because there is a white spot or a pit at the pavilion or there is an inclusion on the pavilion or the culet has a problem but the face of the diamond is absolutely fine; such diamonds are very cost-effective as they are less expensive and the flaw can be easily hidden in the setting.
  • Black rhodium settings merge with the black diamond thus are a great way to make the diamond look blacker and bigger. Black rhodium also gives an edgy look to the jewelry

Experiment with shapes if you want your jewelry to stand out. Try rose-cut diamonds they look bigger and unique.

Black Diamonds v/s Diamonds

  • Diamond is an allotrope of carbon like graphite. The carbon atoms in a diamond are arranged in a variation of the face-centered cubic crystal structure. Black Diamonds are polycrystalline diamonds found in alluvial deposits. These diamonds are made up of many tiny diamond crystals and are therefore porous.
  • Diamonds due to their extraordinary optical characteristic have very few impurities or inclusions. They are clear, colorless and mostly transparent. Black Diamonds have heavy inclusions mainly graphite that is blackish in color thus making them opaque.

Black Diamonds v/s Diamonds

  • Diamonds have high optical dispersion that is the ability to disperse light in different colors which in turn grants them the brilliance and sparkle. Black diamonds being porous and opaque do not disperse any light, rather the black inclusions absorb the light, and thus they do not sparkle like white diamonds.
  • Diamonds are the hardest materials existing, but this hardness also makes them very brittle. A harsh blow can cause the diamond to break. Black diamonds are fragile due to their porous composition and heavy inclusions. A harsh blow can cause the diamond to break or chip.
  • Diamonds are valued for their transparency that is clarity, color, size and cut for the brilliance. Brilliant cut in round diamonds is know to grant maximum brilliance to the diamond. Diamonds are usually cut in limited styles to maintain the brilliance. Black Diamonds are also valued for the color, clarity, size and cut. Black diamonds can be cut in any desired shape without bothering about the brilliance.
  • Diamonds are one of the most expensive gems, due to their rarity. They make a great investment as their value has witnessed a constant acceleration. Black diamonds are cheaper than white diamonds but their value has grown many folds over the last five years.
  • Diamond has look alikes like Cubic Zirconia, synthetic diamonds, crystals, silicon carbides or similar stones like White topaz and more expensive white sapphire. Onyx, Jet, Black crystals etc.
  • Diamonds are treated to improve the white diamond’s color grade color and clarity, including laser drilling to remove inclusions, application of sealants to fill cracks. Black diamonds are mostly treated to enhance the dark gray color to black, they may be irradiated or heat treated.

Diamonds in the Rough – The Hot New Trend!

Edgy and crude, the rough diamond jewelry is the unusual jewelry trend that is becoming very popular. The main reason behind the popularity of rough diamonds is that they are one of a kind. Though each diamond is different they still have a defined shape and matching pairs can be made, but in rough diamonds no two diamonds look the same. In fact even in a pair of earrings the diamonds may have a somewhat similar shape and color but they are nowhere identical.

There is a romance, quirk and mystery in their imperfection that allures everyone towards them. The irregular shapes are set in asymmetrical designs enhance their individuality. In fact the jewelers have to create unique settings to set the stones based on the different shapes of the raw diamonds. Like sometimes just a thin silver or gold wire is wrapped around the diamond to hold it in pendant or a ring. The variation and variety of designs available in rough diamond jewelry goes beyond imagination.

Diamonds in the Rough - The Hot New Trend!

Rough diamond jewelry offers immense room for experimentation. Now a day’s everyone is getting picker and is looking for something unique. Rough diamond quickly answers this requirement. You can create a distinct style with just a single piece of jewelry. A yellow and orange slice diamond necklace in yellow gold or a dark-brown rock studded in pink gold can help you achieve a unique style. Necklaces, earrings, bracelets or rings the choice is immense.

 

The reasonable cost also makes rough diamond jewelry popular. Rough diamonds are in abundance and thus very economical. Firstly because these diamonds are not cut and polished like the other finished diamonds, thus suppliers save on a lot of cost. Secondly in rough diamonds the suppliers do not have to worry about the diamond brilliance and sparkle, as diamonds of all qualities can be used. Rough diamonds of all colors, with inclusions, translucent or opaque are used in jewelry; such diamonds are usually less expensive.

The innovative designs of rough diamond jewelry instantly capture everyone’s curiosities. While buying a rough diamond do remember that a diamond is diamond, a unique mineral from the earth and nothing can replace it. So if you like something very out of the box but do not want to spend too much, then rough diamond jewelry is for you.

BLACK DIAMOND GRADING & CERTIFICATION

Black diamonds have a distinct construction, typically have inclusions and are opaque. A perfectly flawless black diamond does not exist. Therefore while grading black diamonds only the clarity of the table and crown that is the face of the black diamond is considered. Since the diamonds are opaque the inclusions below the girdle do not influence the face of the stone and can be easily hidden under the settings.

Clarity or purity refers to how clear and void of inclusions is the diamond. In black diamonds, however, more crucial is the locations and visibility of the inclusions. Black diamonds typically have inclusions that may or may not show on the surface. As long as the inclusion is not disrupting the shape, color or face (top surface) of the diamond the diamond can be graded high.  There can be like gray spots, scratches, pits, cleavages, cracks, clouds, cavities, crystals, feathers, surface grains etc. Learn more about the inclusions here…

Color is the second most crucial criterion for grading black diamonds. The best quality diamonds have a uniform and lustrous mid-night black color; however it a rare exception.   Most diamonds when mined are either gray, dark green, charcoal sometimes even muddy white. These diamonds are therefore treated to get a rich black color. Apart from the color being dark it is equally important that it should spread across the diamond uniformly. The diamonds with gray or white color patches are not considered good. Black diamond color is usually referred to Fancy Black, as its one of the fancy colored diamond.

Shape or cut of the black diamonds is equally vital. A disproportioned or off-shaped diamond does not sell. Though a slight defect can be covered by the setting but major defects affect the diamond grading. The problem of disproportioned occurs only when there is an inclusion at a crucial place of the diamond. The cutters are compelled to retain or camouflage the inclusion to avoid the breaking of the diamond or decreasing the carat weight.

Carat weight– Black diamonds are rare and larger stones are even rare. So like all diamonds, the cost of the black diamond too escalates with the size of the diamond. The bigger the diamond the higher will be the price considering the other grading factors as well. Another interesting point to note here is that black diamonds are denser and are therefore heavier. A white diamond of a particular millimeter size will weigh more than the black diamond of the same size.

BLACK DIAMONDS ARE REAL & NATURAL

Black diamonds are the latest in the jewelry trend. Though they are nothing like what we usually associate Diamonds with -neither white or transparent, nor do they sparkle, but Black Diamonds exist naturally and are real diamonds. Their stunning appearance has charmed celebrities and designers alike. Mysterious dark color, smooth luster and the realistic price is what pulls everyone towards them. However Black diamonds are very different from the regular diamonds.BLACK DIAMONDS ARE REAL & NATURAL

Black diamonds like the regular white diamonds are crystallized carbon. However they are black and polycrystalline therefore also called Carbonados. Each black diamond is made of multiple micro-crystals that have vacancies so when light falls on the diamond it gets absorbed causing the diamond not to sparkle. Since black diamonds do not sparkle they are evaluated on the basis of the clear surface, luster and color.

The color of the black diamonds is due to the numerous dark inclusions and factures that have stained due to the high temperatures. Typically gray, dark gray, dark green or brown, very-very rarely one comes across a rich black diamond. Even the finest quality natural black diamonds have a metallic blackish dark green or deep brown color. However for the diamond to be graded high, it is imperative for the color to spread uniformly across the stone.

Natural black diamonds that have not been treated radiated or heated are a rarity and are thus very expensive. Moreover natural black diamonds above 1.00 carat without surface or visible inclusions are even rarer. Untreated- unheated natural black diamonds are typically opaque, with high luster and a metallic appearance. GIA does the grading of only natural untreated black diamonds.

Treated/enhanced -though most of the black diamonds available in the market today have been treated/enhanced but they are still 100% natural. The treatment is either to enhance the color or improve the clarity of the diamonds. The treatment usually involves heating or irradiating the gray or dull green real diamonds to get a rich black color. Treated or not as long as the diamond has uniformly rich color and does not show any inclusions on the surface it’s a great diamond.

BLACK DIAMONDS ARE CARBONADOS?

Yes, Black Diamonds are Carbonados – Carbonados have all the properties of the real diamonds but are dark grey- greenish black in color and are porous. The color of the Carbonados resembles charcoal, in fact the name ‘Carbonados’ means “burnt” in Portuguese. They were first discovered in Brazil around the 1840’s, though are supposed to be more than 2.6 to 3.8 billion years old. Carbonados have greater hardness than diamonds therefore were primarily used as abrasives and for cutting glass etc.

BLACK DIAMONDS ARE CARBONADOS?

Origin – There is quiet a hullabaloo about how Carbonados came into being. The most common theory suggests that black diamond like regular white diamonds are also formed from carbon under high-pressure conditions in the bowels of the Earth. Shock metamorphism induced by meteoritic impact on the surface of the earth and radiations-induced by abrupt fission of uranium and thorium are a couple of other theories. Few others argue that Carbonados or Black diamonds have come from the outer space. They believe to have fallen as meteors on earth millions of years ago. Thus are found in alluvial, sedimentary deposits instead in the bowels of the earth and have unusual properties. Moreover the availability of Carabonados is limited to the alluvial deposits in the Central African Republic and in Brazil. To support this theory it has been lately discovered that the micro crystals in Carbonado have traces of nitrogen, hydrogen, and osbornite which are otherwise found only in meteors.

Unique Constitution – Carbonados or Blacks diamonds are very different from white diamonds- they are black and do not sparkle. Carbonados are polycrystalline, ploy means many and crystalline means crystals; which mean carbonados are made of multiple nano/micro crystals sticking together unlike a white diamond that is one single crystal. These micro-crystals have vacancies in them that make them porous. Moreover when the light falls on the diamond it gets absorbed or lost in these vacancies rather than being reflected back which is why they do not sparkle.

The Color– Black diamonds apart from being porous have heavy inclusions mostly graphite, pyrite or hematite that render the diamond opaque. These inclusions play an important role in determining the color intensity of the black diamonds. The color is also the result of the numerous cleavages or fractures that have become black due to graphitization. The color of the natural Black Diamond may range from grayish black to charcoal or dull gray depending on the inclusions. These not so perfectly black diamonds are heated or irradiated to improve the color. Natural-color black diamonds typically opaque and have a high luster that gives the stones a metallic appearance. However black diamonds are rare especially the naturally occurring black colored diamonds are very rare and are therefore very expensive.
