‘Carbonado’ is another term for black diamonds; they are believed to be formed in supernova explosions. Apart from industrial purposes, black diamonds were considered by jewelers as worthless until recently; you should know this before you learn how to buy a black diamond. Black diamonds are used these days in men’s rings in combination with little black dress (LBD) and in making engagement rings fashionably unique. But black diamonds are still more of an eccentric oddity in fashion.

Important Note! I highly recommend you visit Online Diamond Store Reviews For our full in-depth look at online diamond retailers.

•The first thing you need to do in buying a black diamond is to check out various prices on the net; compare as many deals as you possibly can

•Along with pink, blue, green ets, black diamonds fall under the category of fancy colored stones; thus the 4Cs of a diamond does not apply to them.

•There is an exclusive color grading system for colored diamonds from GIA. One is the GIA colored Diamond Grading Report which is like the usual stone grading report; and the other is the GIA colored Diamond Identification and origin report which gives the grade and nature of the color. These are the reports that you need to look for when buying black diamonds.

•To enhance its appearance, a poor quality black diamond is treated; therefore ask if the stone has been treated. Place a fiber-optic light on the diamond to detect if it has been treated with high radiation. On the opposite side of the stone where it has been enhanced or treated, a darkish green comes out.

•Contact an independent appraiser to have an appraisal on your black diamond.

•Although large solitaire sizes of black diamonds are really hard to find, small carats are easily available; most black stones are used in a pave setting. So shopping for black diamonds will need time.

•As compared with clear diamonds, naturally black diamonds are more brittle and they have many inclusions. You cannot find naturally black diamonds with very little inclusions; this is what gives color to the stones according to GIA.

•Due to the rarity of black diamonds, most people buy them from local vendors because they do not have any mental reference to find out what the black diamond is like. Local vendors have limited stocks unlike when you buy online; therefore internet purchase is your best option.

•There is risk involved in cutting black diamonds because of their relatively brittle nature. Thus, a good cut black diamond can be very costly.

It is important that before you purchase a black diamond, you know how to read the grading certificate that comes with the stone and you have learned the basics of stone appraisal.

From: affordable diamond rings. Contrary to what we commonly know, diamond jewelries are not always clear.  Colored diamonds are becoming more popular compared with the usual white and transparent diamonds even though naturally colored gem stones are more expensive.  Some companies are giving some of their gems color treatment to make it more suitable for some customers, budget-wise.

Treating gems with color would be by inducing the stones into extremely high heat to change the color.  It could also be painted.  When appraising color-treated diamonds, they tend to be more affordable since the color are less intense compared with the natural ones.  

There are different shades and colors for naturally colored diamonds.  But there are popular color shades and combinations, they are the pink, blue, brown, yellow, orange, green and red.  Interestingly, there are also black diamonds.  Yellow colored diamonds are the most common, while those in red, blue and green are the rarest. 

When buying naturally colored gems, they are evaluated and checked just like the white and transparent ones.  The 4 Cs are still used in grading colored gem stones:  cut, clarity, color and carat.  However, the way or the factors how colored diamond are inspected are different. 

– Color.   Naturally colored gem stones’ value would depend on the intensity of its color and its hue.  The more intense and vivid the color is, the value of the diamond also increases.  There would be times when there are traces of other color.  If the traces of the secondary color magnifies the beauty of the stone, then that would be great for the value of the stone. But if the underlying color is not complementing the main color, then it lowers down the diamond’s value. 

– Cut.  A diamond’s cut gives the brilliance to the gem stone.  The cut would enhance the intensity and the shade of the diamond’s color.  Most colored gem stones are in round, oval, and princess cuts.  There are also some that would be heart shaped and other unique shapes. 

– Clarity.  Clarity is important for white and transparent diamonds, but for naturally-colored gem stones they may not be as important.  

– Carat.  Carat is all about the weight of the diamond and not about the size.  Of course, the bigger it is the heavier it will be.  The heavier the colored diamond, the higher its value.  

Just like when purchasing white diamonds, obtain a grading certificate from the retailer.  Make sure that the certificate is issued by international laboratories like the IGI, GIA or EGL.  This certification would be your assurance that what you have bought is indeed a natural colored diamond and not a stone that was tampered with. 

The most popular colors would be in yellow and pink.  There are celebrities who fancy wearing colored diamonds.  Over the years, the demand for other colors is also increasing.  Another subject of curiosity would be the black diamond which is sometimes associated with both luck and being unlucky.  Most legends would say that black diamond jewelries are cursed and would bring bad fortune to those who own it. But different from other colored gem stone jewelries, black diamonds are mainly used for industrial purposes.
