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.
