Dark by design. Nothing unnecessary.

Calder pairs a polished black stainless steel setting with flush-set black agate for a clean, near-monochrome finish.

THE STONE

Black agate is known for its deep colour, smooth finish and subtle natural variation.

THE MEANING

Black agate is traditionally associated with stability, grounding and protection.

THE CALDER

A dark natural stone set flush into a sharp black signet. Understated, modern and deliberately restrained.

RING SIZE GUIDE

FIND YOUR SIZE

If you already own a ring that fits well, measure the inside diameter in millimetres and match it to the chart below.

If you do not have a ring to measure, use the finger-measuring method further down the guide.

RING SIZE CHART

Already own a ring that fits? Measure straight across the inside of the ring at its widest point and match that measurement to the chart.

No ring to measure? Measure around your finger and match the result to the Finger Circumference column.

HOW TO MEASURE YOUR FINGER

You will need a strip of paper or a piece of non-stretch string.

Wrap it comfortably around the base of the finger you intend to wear the ring on.

Mark the point where the ends meet.

Lay it flat and measure the length in millimetres.

Match that measurement to the Finger Circumference (mm) column above.

FOR THE BEST FIT

Measure the exact finger you intend to wear the ring on.

Measure when your hands are at a normal temperature. Fingers can become slightly larger in warm conditions and smaller when cold.

If your measurement falls between two sizes, choose the larger size.

STILL UNSURE?

If you are between sizes or unsure which measurement to use, contact us and we will help you choose the closest fit.
