Let customers speak for us

I recently had a custom made opal necklace done by Iona and what can I say it’s simply stunning. Iona’s attention to detail and workmanship is second to none. Hand crafted in 9ct gold with all the beautiful curves. Pictures didn’t do it justice once I received it and opened it up I was in tears at how beautiful it really is. If you are wanting any custom made pieces done Iona is the one for the job. Thank you again!

Amazing

I bought this for my husband as a birthday present as he is obsessed with boulder opal. We changed the chain ourselves but he absolutely loves it. It’s a beautiful pendant and the blue and green is amazing. So impressed with delivery too. Received it the day after I placed the order. Very efficient, I will definitely buy from this site again

Handcrafted Australian Opal Chip Sterling Silver Pendant Necklace

Incredible Quality

I’m blown away by the quality of this opal. The play of colour is even better in person, and the photos didn’t do it justice. It’s perfect for the project I’ve been working on, and I’ll be back for more soon!

A stunning piece of magic.

Absolutely gorgeous opal! The colors are so vibrant and change beautifully in different light—it’s like a little piece of magic. Shipping was fast, and the packaging was lovely. I’ll definitely be purchasing more opals from Iona!

Coober Pedy Opal 1.3carat Solid Hand-Cut

Australian Opal!

I love opal! I've been wanting one forever but I was a bit nervous purchasing something like this from overseas. Iona assured me and the process was just as smooth as if I purchased here in the UK. The opal arrived in beautiful packaging and was well packed for safe travelling. I am so happy with it. It is better than it looked online and I thought it was beautiful there. I think I will be buying more now I have my first!

Thank you, Iona

I purchased an opal from Iona and had her set it in Sterling Silver for me. I'm so pleased with the result. She consulted with me along the way providing progress updates on the everything. The opal had to be cut down a little but she took the minimum amount off so we could save the size. Iona goes above and beyond for her customers. I highly recommend.
