1.36 ct Blue Sapphire-Color Change - Cushion

This 1.36-carat color-change sapphire is cut as a cushion measuring 6.8 x 5.7 x 3.7 mm, with a blue body color, sourced from Tanzania.

Sapphire is corundum, one of the hardest materials in the gem world after diamond, and it comes in every color the species holds except the red the trade reserves for ruby. Tanzania's deposits at Songea and Tunduru produce sapphire in an unusually wide range of colors. It is entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

One of a kind, it exists exactly once; there is no second example to size up or down. It is the rarer object, and the kind of gemstone that becomes an heirloom. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
