1.11 ct Gray Opal - Trillion

At 1.11 carats, this opal from Ethiopia carries its gray color through a trillion cut, measuring 8.8 x 8.8 x 6.6 x 4 mm.

Opal is hydrated silica that can break white light into a play of living color, a fire no two stones repeat; it holds up to a fifth of its weight in water, which is why it glows in a way nothing crystalline does. Ethiopia is one of the newest names on the gem map, now a leading source of bright opal as well as other species. It is wholly untreated, its color finished by geology rather than by any furnace or enhancement.

A genuine opal at a size and price you can actually wear, the real thing rather than a machine-grown copy. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
