Color-Change Diaspore

Diaspore, sometimes marketed under the name Zultanite, is a color change gem from Turkey recently introduced to the international market. Diaspore is a hydrated aluminum oxide colored by manganese. It was first faceted as a gemstone in the 1980's, but has never been mined commercially until recently. With reasonably good hardness (6.5 to 7 on the Mohs scale) and good brilliance, diaspore has been attracting considerable attention in the gem world.

Under natural or fluorescent light, diapsore has a kiwi green color, with flashes of yellow. Diaspore displays a champagne color under incandescent lighting, and when exposed to subdued lighting, such as candlelight, it has a pinkish color. The larger the stone, the more pronounced the color change effect will be.

I found a beautiful pink sapphire that's almost a carat for under $80! There's no way you can find that kind of value anywhere else.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
