Black Diamond Facts
Keeping with my latest obsession of diamonds, I thought I should touch on a huge trend right now in jewelry…Black Diamonds! But first, here’s some info.
For a quick buyers guide (white diamonds) and a real life example of what to look out for, see the post on Anjolee Diamonds.
- Black diamonds, AKA: “Carbon Diamonds”, gain their color (Yes I know black is not a color, thanks) from clusters of tiny random inclusions through out the structure of the stone. This is unique in its own way as most other gyms owe their pop of color to other elements (boron, nitrogen, titanium, iron and Corundum, to name a few) that creeped in during formation.
- A pure black diamond has 98% light absorption, giving them a unique luster that seems to emanate from within.
- If you have already figured it out, Black diamonds are typically opaque, which can really lower the cost. Since the cut of the diamond doesn’t lend that much to the refractive properties, black diamonds are less labour intensive and as such cheaper. Note: they still display the wonderful ‘adamantine’ luster 9A very high mirror-like luster) almost completely unique to diamonds.
- High quality stones can be pricy, but the more common ones with shards of clear or gray through them are very charming and affordable.
- Most famous of the black diamond crowd:202.00K Black Star of Africa and the 67.50 K Black Orfloff.
- They’ve only recently regained some style momentum as in the past they were difficult to cut and polish due to the fact that are, harder (have a high hardness rating) that exceeds their brother and sister diamonds.
Get this: Black diamonds are found in Brazil and Central African, but in other mining locations ( Russia, Australia, Canada, and African countries). This had geologists stumped for the longest time, and in addition, normal diamonds are found in what is called kimberlite pipes where they travel from the Earth’s crust to the surface. Black diamonds, on the other hands are exclusively found in alluvial deposits ( I know, super technical), suggesting that they did not form deep in the earth.
Putting it together: Back in 06, Stephen Haggerty’s team of Geo specialists from Florida International University in Miami, presented evidence that the illustrious black diamond came from space via a massive asteroid (over .5 a miles, or 0.8 Km wide) that smashed into the earth (like me at a sample sale) over a few billion years ago, when South America and Africa where still part of the same land mass. How hot-as-balls is that!?!
“Oh wow, where did you get your back diamonds from?”
“Oh thanks, yah, they’re from space, no big deal”.
