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.

Great selection. Love the many learning features like articles and gem information. Prices competitive for natural stones. I do miss not having a selection of lab-made stones, CZ’s, etc, which are useful when price and cost are factors.

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
