3.90 ct Colorless Opal - Oval

This 3.9-carat opal is cut as an oval measuring 10 x 8 x 4.5 mm, showing a colorless face, 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 entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

No two of these line up the same way on color, cut, and origin at once, which is what makes choosing this one feel deliberate. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
