Rockstream Blue - A vivid opal seam shining through its matrix base, its deep blue flashes flowing like moving water carved into stone.

This unusual boulder opal ring features a polished 10 × 8 mm freeform stone set across the face of a 925 silver band.

The opal shows deep blue tones with subtle pinfire, resting within its natural ironstone base for an earthy, organic look.

The seam continues through to the reverse, making the back just as interesting as the front.

With brightness 3 and a smooth polished finish, it’s a striking miner‑direct piece full of natural character.

The ring is adjustable, making it easy to fit and comfortable to wear.
