A gemstone the ancients called the queen of gems. This natural Australian opal engagement ring sets a round opal — a full ~1 ct of drifting rainbow fire — between rows of bright simulated diamonds, all crafted in vintage-inspired 14K rose gold vermeil over sterling silver 925. It is a proposal ring with history and soul: a non-traditional engagement ring, promise ring, or October birthstone gift that feels genuinely one of a kind.

The natural Australian opal
Australia is the source of the world’s finest opals, and this round stone is a genuine natural gem — its play-of-color born from the way light refracts through microscopic silica spheres, never from dye or coating. The result is a shifting display that can range from soft pastels to vivid flashes of the entire rainbow. Because that fire forms uniquely underground, every opal is one of a kind; yours will share the luminous character of our photos with its own singular pattern. For help choosing your stone, our opal engagement rings guide covers color, body tone and cut.
Bright simulated diamond sides
Flanking the opal, rows of simulated diamonds (crisp, brilliant cubic zirconia) frame the center with a cool, classic sparkle that makes the opal’s colors sing. It is a bright, budget-friendly way to bring traditional engagement-ring shimmer to a decidedly non-traditional stone. Prefer a lab-grown diamond or moissanite upgrade? Message us — most designs can be tailored.
Centuries of opal lore
Opal has been treasured for millennia as a stone of hope, purity and truth. The ancient Greeks believed it granted the gift of prophecy; nomadic Arab traders thought each opal held lightning fallen from the sky. Prized as a gem of balance and emotional clarity, it has always been a stone for dreamers. As October’s birthstone it carries that meaning forward — our October birthstone guide tells the full story, and our complete opal guide dives deeper into the many faces of the gem.

Frequently asked questions
Is the opal natural?
Yes. This is a genuine natural Australian opal, with play-of-color that forms naturally inside the stone — never dyed or coated. That is why each opal is unique and yours will look subtly different from any other.
What is rose gold vermeil?
Rose gold vermeil is real 14K gold layered over sterling silver 925. It gives you the warm, golden look of rose gold at a far easier price than solid gold. If you would like gold all the way through, the same design is also available in solid gold.
How big is the opal?
The round center measures 6.0 mm x 6.0 mm, roughly 1 ct — a generous, confident size that makes the opal’s rainbow fire the clear focus of the ring.
What are the side stones?
Rows of simulated diamonds — bright, brilliant cubic zirconia — frame the opal with a crisp classic sparkle. If you would prefer a lab-grown diamond or moissanite upgrade, message us and we will tailor it.
Will my opal look exactly like the photos?
It will share the same luminous rainbow character, but the exact pattern of fire is one of a kind — the hallmark of a natural opal. No two are ever identical, so yours is truly unique.
Can I wear it as an engagement ring?
Absolutely. It is designed as a non-traditional engagement ring, and it also makes a heartfelt promise ring or October birthstone gift.
Is opal durable enough for daily wear?
Opal sits around 5.5–6.5 on the Mohs scale, so it is a softer gem that rewards a little care. Worn mindfully — off for heavy chores and sports — it makes a wonderful everyday ring.
How do I care for the ring?
Remove it before showering, swimming or exercise, keep it away from lotions and fragrance, and store it dry in its gift box. A soft, dry cloth restores its shine.
Can this ring be resized?
Yes. Choose your size at checkout, and if the fit is not quite right, resizing is available and starts from a modest fee. Contact us and we will guide you.
Is opal the October birthstone?
Yes. Opal is one of October’s birthstones, long associated with hope, purity and truth — which makes this ring an especially meaningful October gift.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear this ring with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free gift box and is backed by our lifetime warranty — ready for a proposal or to give as a keepsake.
