Have you ever seen colored Diamonds?
We just have to share a couple photos of these immaculate naturally colored diamonds that we had the pleasure of observing at JCK.
Diamonds are of course one of the most precious gemstones in the World and according to most recent data Blue Diamonds are the World's most valuable gemstone.
We cherish all gemstones, however colored Diamonds have a special place in our hearts. I mean... look at those pastels.
What causes different colors in Diamonds? We're so glad you asked!
Diamonds get their color from trace elements elements trapped during formation or structural defects in their crystal lattice.
• Such as blue Diamonds occuring as a result of boron impurities, which absorb yellow light.
• Yellow and orange Diamonds are caused by nitrogen impurities absorbing blue light which then produce warm golden tones.
• Pink and red Diamonds are exposed to extreme pressure (more than the traditional high pressure Diamonds are created under) that alters the crystal structure thus reflecting red light.
• Green Diamonds are exposed to natural radition within the earth over millions of years, damaging their internal cystal structure. Specifically, by knocking the carbon atoms out of their posiotions. This structural change creates "vacancies" (missing atoms) known as GR1 centers, which affect how light is absorbed and reflected, causing the stone to appear green.
• Black Diamonds (also known as Carbonados) naturally have a polycrystalline structure, so, instead of being one single crystal, they are composed of millions of tiny interlocking included diamonds fused together. However, when a Diamond's composition is essentially clouds of dark mineral inclusions like graphite, pyrite or hematite (and more), they can be heat treated, resulting in an entirely black Diamond, yet retaining a single crystal structure.
Which one is your favorite?✨
