The Coastwhisper - A freeform opal that glows like a quiet coastal inlet, blue light gathering at the edge of earthy matrix like sea meeting land.
This full‑face boulder opal pendant features bright flashes of blue, green and red across its polished freeform surface.
With brightness 5, the colour play is vivid and dynamic, shifting beautifully as the pendant moves.
The 20 × 12 × 3 mm stone has an organic freeform shape that feels bold yet elegant, finished with a removable silver‑tone bail so it can be worn on either silver or gold chains or a leather cord.
A miner‑direct statement piece with striking mixed‑pattern colour and a smooth polished finish - perfect for anyone who loves bright, premium opals.
