A rare and breathtaking Australian black opal and diamond cluster ring, expertly crafted in luxurious platinum.

At its centre lies a magnificent oval cabochon black opal, weighing approximately 1.20 carats, and exhibiting exceptional play-of-colour with vivid flashes of electric blue and green shimmering against a dark, velvety background. The opal is securely claw-set and framed by a dazzling halo of eighteen brilliant-cut and two princess-cut diamonds, with a combined weight of approximately 0.40 carats, adding light and brilliance to the design.

Mounted in finely polished platinum, the sleek band offers a clean, contemporary contrast to the vibrant centre stone, enhancing the overall elegance of this one-of-a-kind piece.

A striking combination of rarity, craftsmanship, and visual impact—perfect for collectors or those seeking a unique and unforgettable statement ring.

Perfection

I bought this ring after searching for a while and was unsure what to expect - how it would look in real life. I was absolutely taken aback at how beautiful it was! It arrived in perfect condition, clean and the most sparkly diamonds. I would 100% order from Elliebelle again.

What a great experience!

If you would like to use a trusted, professional but friendly service, then this is the site for you. I had never used an online service for a very expensive item, but when I rang to chat and asked for advice, Lee took me through everything and the next day as promised my beautiful ring arrived, safely packed with everything intact. Thank you so much.

Look and you will find!

Thank you so much for my gorgeous ring, delivered yesterday. I will always cherish it as a memory of my Mum. It is a replacement for a1930’s Ceylon sapphire ring given to me by Mum, but sadly lost 4 years ago. A group of ladies browsing rings in a jewellers yesterday admired my ring, I told them about your company, and how easy it is to find such beautiful rings on your website. I will always promote Ellibelle when I have the opportunity! Once again, thank you.
