Boulder Opal Pendant – 18K Gold, Two-Stone Drop, 1.02ct

This pendant sets two Queensland boulder opals in a vertical drop — a slender teardrop stone above, a bolder triangular stone below — both bezel-set in 18 karat yellow gold on a fine gold chain. Vivid green dominates both stones, with blue running through in streaks and small flashes of red catching the light at certain angles. The dual-stone arrangement gives the pendant a longer drop than a single-stone piece, and the graduated shapes — narrow above, wide below — create a sense of movement rather than a static, symmetrical hang. It reads equally well dressed up or worn day to day.

About Boulder Opal

Boulder opal forms as veins of precious opal within ironstone matrix in the opal fields of Queensland — primarily Quilpie, Yowah and Winton. Unlike black opal from Lightning Ridge, the opal cannot be separated from its host rock; it's cut as a single solid piece, with the natural brown ironstone remaining as the stone's backing. This gives boulder opal its distinctive look — vivid colour against rich earth tones — and also makes it physically more durable than other opals, since the ironstone host is harder than the opal layer it carries.
