Set in a gold-toned frame with a fluted side and a fine beaded rim, a black onyx heart sits on a thin, plain band. Worn alone it looks sweet and graphic, and next to a slim gold band it makes an easy stack.

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.
