A diamond ring is a very personal item and should fit perfectly. If you already have a ring that fits perfectly, measure the inner diameter with a precise measuring tool, preferably a caliper. Or discover, more ways to measure your perfect ring size.

If the ring size appears to be too large or too small after your purchase, most ring designs can be adjusted without any problem. The exact amount charged for the size adjustment depends on the ring design, the material, and the number of sizes the ring needs to be adjusted.
