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.

when I need a colored stone I check gem select. a trusted supplier for at least 10 years for me. many of the online sites have gone black but gemselect continues to satisfy me. oh sure there are many windowed and poorly cut stones here so paying some attention is critical. remember these are not custom cut stones but rather cut by old methods and the aim is to keep weight up at the expense of optical perfection. remember that colored stones are about color as the first consideration. I just wish gemselect offered rough for those who want to cut it.

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
