Our new BONBON Ring, made even more precious. Crafted in solid gold, the ring pairs smooth, sculptural curves with the brilliance of an oval-cut diamond. Bold enough to wear alone, easy to make part of your everyday.
Make it yours: choose 14k or 18k solid gold, with a lab-grown diamond or a GIA-certified natural diamond.
A gift to mark something special—or simply a ring you’ve chosen for yourself.

Our jewellery is crafted by skilled artisans in Bangkok, Thailand, in partnership with an experienced jewellery manufacturer.
Each ring is made to order in your choice of 14k or 18k solid gold, with a lab-grown or natural diamond. Every diamond comes with its own certificate.
When it comes to finding the perfect fit for your ring, it's important to know your ring size. Use the chart below as a guide to determine your ring size.
Determining the Size Using Your Current Ring
1. Take the ring that fits you perfectly.
2. Measure its inner diameter (in millimeters).
3. Use our size chart to determine your size.
If You Don't Have a Ring
1. Wrap a strip of paper around your finger where you want the ring to sit.
2. Make sure the paper fits snugly – the tighter, the better, to ensure the most accurate measurement.
3. Mark where the paper overlaps and measure the distance using a ruler (in millimeters).
4. Use our chart to determine your size.

As Seen In
Our founder Lilia spent hours exploring her grandmother's jewelry box as a child, fascinated by treasures that were rarely worn. Copine was created to change that jewelry made to be lived in, every single day.
At Copine, we believe the materials matter as much as the design. We work with recycled brass as our core metal, paired with carefully selected natural stones — jade, aventurine, lapis lazuli, onyx and agate. Colour is at the heart of what we do, which is why we work extensively with enamel — and why Thailand became a natural partner. Thai artisans have a long tradition of jewelry craftsmanship, and that precision and care shows in every piece we make together.
