Usually this means the diamond is natural but not the color -- it was colored to be black. Depending on the process used to color the diamond, the "color enhancement" is either permament regardless of what happens to that diamond or permanent with normal wear and tear (meaning it could lose it's black color in certain sitations - like if subjected to extreme heat).
The biggest diamond ring ever made is called The Spirit of de Grisogono. It weighs 312.24 carats, or 62.45 g. It is also a black diamond and is the largest black diamond ever found.
No, the color of a diamond does not affect its weight. The weight of a diamond is measured in carats, and this is based on the diamond's mass, not its color.
The largest GIA certified black diamond available in a quick Internet search is a Fancy black, cushion cut, 7.21 carat diamond with a retail price of US$18,125. You may be able to shop longer and find a larger diamond, and the cost will be comperable to its individual characteristics.
Natural and Genuine are two different things. To find natural black diamond beads is almost impossible as 99% of all black diamonds have been treated for color and that's how they are sold, even at high-end retailers. What you need look out for is a genuine black diamond beads company who is selling diamond and not another look-alike stone such as spinel or hematite. I searched on Google for a good source and it looks like beacab.com may be a genuine supplier. You can also ask them about natural black diamond beads and whether they have any - from their website they have used the word "genuine" but not natural. Good Luck!
Assuming you are asking the color of "Carbon", most forms are black. There are three "allotropes" of Carbon: Graphite, Diamond, and Amorphous. Diamond is clear but of course quite rare.
You can get a diamond color enhanced through coating or polishing.
Your answer depends on the quality of the diamond, the metal in the setting and the design work involved. You will pay more for a natural black diamond than for an enhanced or man-made stone.
I think it is an "enhanced" diamond.
The value of anything is worth whatever someone will pay you for it. Bests practices dictate that you take your diamond to a certified gemologist and pay for an evaluation of the stone, including its cut, colour, carat weight and clarity. Without endorsement, you can use the link, below, to shop for a comparable black diamond which may or may not be enhanced. Once you find the diamond to compare, you can use the other link to convert the dollar amount to S A Rands.
You can have the clarity of a Diamond assessed at a Jewellers, often the item may be needed to be sent away. With an Enhanced diamond the diamond has been treated to achieve a better clarity than it originally had.
