Crafted just for you, this customisable piece can be made from new materials or reimagined using gemstones from jewellery you already treasure.
Be transfixed by The Cosima 1.16ct Aquamarine Ring, an eye-catching halo treasure inspired by vintage finery, that glistens with an ocean-like aquamarine at its centre.
Why we love this ring:
- 1.16ct cushion cut aquamarine imbues the ring with a distinct look
- Halo of eighteen bezel set diamonds plus two trios of bezel set side diamond clusters totalling 0.36ct swathes the centre stone in an endless sparkle
- Milgrain bezel setting protects centre stone while adding unique detail for additional flair
- Half-rounded band for comfortable wear
- Crafted with 18ct recycled yellow gold for a lifetime gleam
Available for made-to-order, thoughtfully handcrafted with recycled yellow gold sourced via our in-house jewellery recycling initiative, Gold Swap.

I’ve turned a very sentimental and precious necklace into the ring of my dreams using the gold swap initiative. Hannah and the incredible team at Molten have been such a pleasure to work along side with making my vision come to life. I couldn’t fault the process and the end result is so stunning and exactly what I had in mind.

One of my favourite jewellery stores in Brisbane. All the items I have bought and worn from Molten are my favourite pieces and I always get compliments when wearing them. If you want unique, stylish pieces, shop at Molten.

The entire process has been seamless, from purchasing, resizing through to pickup. All of the ladies I dealt with were extremely helpful, bubbly and made our experience feel extra special, keeping us informed with frequent email or phone updates. We cannot wait to use them for our wedding bands as well!

The team at Molten Store are so helpful and lovely to deal with! My mum and I had custom rings made using the Gold Swap program and the girls were so patient and kept us informed at every stage. Both of our rings are so beautiful. Definitely recommend!
