The Oceancrest - A boulder opal doublet ring that looks like a clear blue ocean, its blue‑green broad flash rippling across the polished round stone like shifting waves over deep turquoise water.
This boulder opal doublet ring glows with a beautiful mix of blue and green broad flash that shifts gently as the light moves.
The polished round stone has a calm, oceanic feel - flashes of turquoise and emerald tones ripple across its surface, giving it a serene yet vibrant character. Set in stamped 925 silver, the ring feels refined and timeless, perfect for everyday wear or gifting.
With brightness 3, the colour play is lively but balanced, making it ideal for those who love opal’s natural shimmer without overpowering sparkle.
Each piece is miner‑direct and one‑of‑a‑kind, carrying the authentic charm of Australian opal craftsmanship.
