The Deepsea Shard - A long, slender boulder opal glowing like a hidden ocean crevice, its full‑face blues and greens flickering with bright pinfire that feels alive beneath the polished surface.
This long teardrop boulder opal doublet pendant glows with a beautiful mix of white, blue and green tones.
The polished full‑face surface shows bright pinfire and mixed patterns that shimmer vividly under light.
With brightness 5, the colour play is exceptional - crisp flashes of oceanic blue and emerald green ripple across the opal’s milky base.
The 31 × 7 × 3 mm stone has a graceful elongated teardrop shape, finished with a removable silver‑tone bail for easy chain changes.
A miner‑direct statement piece that feels refined, luminous and one‑of‑a‑kind.
