Product Overview

Green fire that stops you mid-scroll — ready for your next pendant.

There's a reason opal cabochons like this one keep showing up in wire-wrap and bezel projects — the color just does something a plain stone can't.

This oval cabochon carries a deep green base with blue-green flashes running through dark matrix veining, so no two angles of light show you the exact same stone.

This is a lab created opal, know the trade names Monarch Opal and Sterling Opal — grown to give you that same play-of-color you'd chase in a natural opal, minus the fragility and the price jump that comes with mined stone.

If you've been searching for a synthetic opal that photographs well and sets easily, this cabochon is cut with a flat back specifically so it drops into a bezel or prong setting without extra prep work.

At 7 carats and 16x21mm, it's sized comfortably for a statement pendant, a large ring, or a focal piece in a wire-wrap design.

AAA grade means you're getting clean color saturation with no dull patches — the kind of stone that carries a piece on its own instead of needing extra embellishment around it.

Product Frequently Asked Questions

It's genuine opal material grown in a lab rather than mined — not glass or resin. Lab created opal has the same mineral structure and play-of-color as natural opal, just made under controlled conditions instead of underground.

Yes, it's cut flat specifically for bezel and prong settings — no extra grinding needed before you set it.

Wipe with a soft, damp cloth. Skip ultrasonic cleaners and steam, and avoid leaving it in direct heat or sudden temperature swings — same care as you'd give any opal.

We photograph each stone individually rather than using a stock image, so what you see is the actual piece you're buying.

Yes — at 16x21mm it works well as a statement ring stone, though a bezel setting will protect the edges better than a prong setting for everyday wear.
