5.41 ct Gray Opal - Oval

This 5.41-carat opal is cut as an oval measuring 15.7 x 13 x 6.5 mm, with a gray body color, sourced from Ethiopia.

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. It is wholly untreated, its color finished by geology rather than by any furnace or enhancement.

Its exact combination of color, cut, and origin is its own, the kind of center stone you choose on purpose and build a piece around. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
