Sizing

Each ring is made to a single size, by hand. Measure the inner diameter of a ring that already fits the intended finger and match it in the chart below.

A note before you measure

Fingers change size through the day. Heat, exercise and salty food make them swell; cold and mornings make them shrink — the difference can reach half a size.

For the truest result:

measure in the evening, at room temperature
not right after sport, heat or a salty meal
repeat two or three times on different days — take the middle
if your knuckle is wider than the base, measure the knuckle too and choose a size in between
between two sizes, always take the larger one — each piece is cast solid and cannot be resized
