Prefer a white gold look? We offer rhodium plating to create a cooler, silvery tone.
Not sure of the perfect size? Many customers purchase the ring in its current size, then claim a complimentary resize after gifting or the wearer tries it on.

Customer Reviews
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!
