Sandwhisper - A calm teardrop opal where tiny blue‑white flashes glint through sandy matrix, shimmering like quiet light drifting under moving water.
This teardrop boulder opal pendant features a natural matrix conglomerate pattern with tiny flashes of blue and white pinfire scattered across the surface.
The 22 × 15 mm stone has a polished finish and a gentle, understated brightness of 2, giving it an earthy, organic look.
The opal hangs freely from a removable 925 silver bail, allowing soft movement and easy styling.
A miner‑direct doublet with a calm, natural palette - perfect for those who love subtle opals with character and texture.
