2.91 ct Yellow Opal - Trillion

At 2.91 carats, this opal from Ethiopia carries its yellow color through a trillion cut, measuring 13.1 x 11 x 4.7 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.

This is a center-stone-grade gemstone with a character of its own, chosen rather than settled for. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
