Earth-mined Australian boulder opal weighing 1.63ct ETW in an oval cabochon with opaque clarity.

The smooth cabochon cut highlights the gemstone's natural surface appearance and individual patterning, giving this boulder opal its own distinctive visual identity.

Boulder opal is a uniquely Australian variety of precious opal that naturally forms within fractures and cavities of ironstone host rock. The opal is typically cut while retaining portions of its natural ironstone matrix, creating individual patterns and contrasts that make each specimen unique.

At 9.8 mm in length, this boulder opal offers excellent face-up presence. Due to opal's relative softness and sensitivity, it is particularly well suited for a custom pendant or collector piece rather than an everyday ring.

Each boulder opal develops with its own natural distribution of opal and host material, making the appearance of individual stones difficult to duplicate.

A distinctive Australian gemstone ready for a custom pendant design or gemstone collection.
