Measure a ring you own
Lay a ring that fits the right finger flat and measure across the inside, edge to edge. Match it to the inside diameter column. -
Use a strip of paper
Wrap it around the base of your finger, mark where it overlaps, lay it flat and measure. Match it to the circumference column. -
Between two sizes?
Choose the larger one. Fingers swell a little in warm weather and later in the day.
Adjustable rings (such as our snake and CZ rings) fit most fingers, so there's no need to choose a size.

Aquamarine is the pale sea blue of the beryl family, and the birthstone for March. A single 6mm faceted aquamarine, four-prong set on a slim 2mm band in 925 sterling silver or 18K gold vermeil, so it stacks easily alongside other rings or wears on its own.
Details
- Stone: natural aquamarine
- Origin: Madagascar
- Cut: 6mm round, faceted
- Setting: four-prong solitaire
- Band: 2mm
- Every stone is natural, so colour varies slightly from ring to ring. We promise the same quality, not the exact stone shown.
Materials
Nickel-free 925 sterling silver, or 18K gold vermeil — a 2.5-micron layer of 18K gold over solid 925 sterling silver.
Sizing
Available in UK sizes J½ to P½ — the size menu shows what is in stock in each metal. The band is solid, not adjustable, so if you're between sizes or unsure, send us a message before ordering and we'll help.
Care
- Take it off before showering, swimming or bathing, and keep it away from perfume, lotions and cleaning products.
- Put your jewellery on last when getting ready, and take it off first when winding down.
- Store it in your Abiza box when not worn, away from other jewellery so the stone and finish don't scratch.
Packaging
Quality-checked and packed in our Chester studio, then presented in our signature Abiza ring box with an aquamarine crystal information card — ready to give. If you'd like a larger ribbon-tied gift box for a special occasion, choose the gift box upgrade at checkout.
March Birthstone, Aquamarine
Aquamarine is March's birthstone. The name comes from the Latin for sea water, and sailors once carried it as a charm for a calm crossing — it has been associated with steadiness and clear speaking ever since. Those are the traditions the stone carries, and every ring arrives with a card explaining them.
These properties are based on traditional crystal beliefs and are not a substitute for medical or psychological advice.
