7.55 ct Colorless Opal - Freeform

This 7.55-carat opal is shaped as a freeform measuring 21 x 13 x 6 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.

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. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
