23.27 ct Colorless Opal - Freeform

This 23.27-carat opal is shaped as a freeform measuring 29.5 x 21.5 x 8.5 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.

One of a kind, it exists exactly once; there is no second example to size up or down. It is the rarer object, and the kind of gemstone that becomes an heirloom. Caveman Gems hand-selects every gemstone and photographs it in good light, to give you the truest look a screen can.
