Beautiful opals, I could walk away without one

I saw this opal sparkling in the sunlight at your stall and couldn’t walk away without it. You were so lovely to chat with, and it’s clear you really know your opals. Thank you, Iona.

One of the Best I’ve Seen

I’ve seen a lot of opals, but nothing like the one I picked up from your market stall. It’s got the most incredible flashes of colour, and the price was very fair for a high grade opal. I’ll be back for more!

Didn’t Know I Needed These! LOL

Stopped by your stall and ended up buying earrings I didn’t know I needed! LOL! The colours are amazing and I love that each opal is a bit different. So unique. Such a great find at the market!

Stunning Opal From Coober Pedy

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!
