‘Summer Night Vibes' ~ Handcrafted 49ct Solid Queensland Koroit Opal Pendant Necklace
Absolutely beautiful ring

This ring is perfect all round. From the feel and finish of the steel to the absolutely beautiful colors of the opals embedded in the inlay. I have a couple of opal rings but this one is my favorite.

Handcrafted Australian Opal Ring Black Surgical Steel Size Z (12 3/4)
Best opals

Fantastic it is great to actually receive Australian opals from an Australian company. We brought this as a replacement for my daughter as she had lost her Opal necklace. Her dad brought her as a child. She was more than happy to receive this one as she loves Christmas and loves opals and as it was from Cooper Pedi it had sentimental meaning behind it as well. It is a beautiful opal. I would highly recommend buying from this company as they are Australian made and I owned

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!
