The Driftseam - A boulder pipe opal with a pale seam running through sandy ironstone, its tiny flashes twinkling like sunken treasures shifting under moving water.
This boulder pipe opal pendant features a polished oval stone with a striking ironstone seam running through the centre and subtle yellow‑orange pinfire scattered across the surface.
The 11 × 7 mm opal sits in a classic 925 silver setting that complements its warm, natural tones.
With brightness 3, the colour play is gentle but distinct, giving the pendant an organic, glowing look.
A miner‑direct doublet with a unique ironstone matrix and soft pinfire sparkle - perfect for those who love earthy, understated opals with character.
