Lightning Ridge Opal 1.6carat Solid Hand-Cut

A Hidden Gem in Townsville

I met Iona and Wayne at the Townsville market. They have some stunning opals and jewellery. I found a gem from Coober Pedy that caught my eye. It looked great that night but oh my, in the morning in the sun, it blew us away! Highly recommend checking out her stall!

Iona Opal Australia

I visited the market in Townsville and came across Iona’s opal stall. I ended up buying an opal ring. The ring is really nice but the fact that Iona had one that fit me was the best. It made my night. I love the Strand markets but even more so when I stumble across stalls like this.

Opal

I’ve been looking to buy an opal for a while now, and Iona’s stall at the night markets had exactly what I wanted. I picked up a beautiful crystal opal with such vibrant colours.

Coober Pedy Opal 1.3carat Solid Hand-Cut

A True Gem at the Market

I stumbled upon Iona’s stall at the market and was blown away by the selection of opals and jewellery. I bought a beautiful opal that has the most amazing rainbow colours. The whole experience was fantastic, and Iona was so knowledgeable about the stones. It made my Townsville market experience so pleasant.

Lightning Ridge Opal 1.8carat Solid Hand-Cut

What a delight

I’ve collected opals for years, and the opal I received from Iona is one of the best I’ve seen. The stone has a striking play of colour and it is very well cut and polished. The customer service from Iona was top-notch, and I’ll definitely be making another purchase soon!

Coober Pedy Opal 1.5carat Solid Hand-Cut

Opal Ring

I’ve always wanted an Australian opal ring, and I’m so glad I bought this one. My new ring is stunning, the opal chips sparkle and change every way you look at it and I have had so many compliemtns when I wear it. You can tell it’s been carefully handcrafted, and I love that it’s a piece of Australian heritage. Shipping was fast too! Very happy with my purchase.

Handcrafted Australian Opal Ring Silver Surgical Steel Size R 1/2 (9)

A Unique Piece of Nature

The opal is absolutely gorgeous. The colours are so vibrant, and the shape is truly unique. I think I now love the freeform as much as you do! I've always wanted a real opal but I was skeptical. I am glad I got to meet Iona in San Diego, she reassured me and I’m thrilled with the stone I received.

Coober Pedy Opal 0.9carat Solid Hand-Cut

Opals from Australia

I purchased a Lightning Ridge black opal, and I couldn’t be happier. The opal is stunning, with color that shifts beautifully in the light. It’s a perfect addition to my collection. Highly recommend if you’re looking for genuine Australian opals! Iona was also available for any questions I had which is nice too. You often don't get to speak to the cutter like that.

Coober Pedy Opal 3.9carat Solid Hand-Cut

Beautiful Opal

My first Opal and the pictures do not do it justice. My wife is excited to fit it in an open pendant so all to colours are on display. Shipping was great and it arrived safely. I will be buying from Iona Opal again.
