One large, flat circle of black onyx in a thin silver rim, sitting on a wire-slim band. The disc covers much of the finger, so it reads as a bold modern piece while the ring stays light enough to wear all day.

Why it's special
Reconstituted onyx is real onyx fused for even color and strength, so the black stays uniform across the whole face. The silver is hallmarked 925, rhodium-plated and nickel-free, and the ring comes in a wide range of US sizes.

Find your ring size
Most of our rings are adjustable from US 6 to 11. Use this guide to confirm your size fits the range, or to pick the right fixed size when offered.
How to measure
Measure a ring you already own
Take a ring that fits the same finger. Measure the inside diameter (across the centre, edge to edge) with a ruler in millimetres. Match it to the chart.
Use a strip of paper or string
- Cut a thin strip of paper (about 1 cm wide) or take a piece of string.
- Wrap it around the base of your finger snugly, not tight.
- Mark where the ends meet, then measure the length in millimetres.
- That number is your inside circumference. Match it on the chart.
Size chart
Match your inside diameter or circumference (in mm) to the row that's closest.

Fit tips
- Measure at the end of the day. Fingers are smallest in the morning and swell slightly by evening, so measuring then gives the most comfortable fit.
- Keep hands warm. Cold fingers can be up to half a size smaller.
- Wider bands fit tighter. If a ring is 6 mm wide or more, consider going up by half a size.
- Knuckle larger than the base? Size for the knuckle so the ring slides on, and pair with a ring sizer if it spins.
- Between two sizes? Choose the larger one: it's easier to resize down than up.
Still unsure? Email info@oliviastarjewelry.com with your circumference in mm and we'll recommend a size.
