6.31 ct Green Sphene - Cushion

At 6.31 carats, this sphene from Madagascar carries its green color through a cushion cut, measuring 12.7 x 9 x 6.5 mm.

Sphene has dispersion higher than diamond, so a well-cut stone throws more fire than almost any other gemstone. Madagascar has produced an unusually wide range of gem species since the mid 1990s. It is wholly untreated, its color finished by geology rather than by any furnace or enhancement.

A single natural gemstone with no duplicate behind it; once it is set or collected, there is no other. It will outlast everyone who owns it, which is most of what an heirloom really is. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
