Ring Sizes

The best way to determine a ring size (if you don’t know yours already) is to get sized by a local jeweler.

To measure your ring size at home, measure the diameter or the circumference of the ring as shown below.

Then use the below chart to determine your size or its equivalent.

Please note that fingers tend to swell a bit over summer and shrink during winter. Keep this in mind while measuring your size and ordering.

If in doubt, order a size up.

Although all reasonable care is taken by Orne Jewels to present true and accurate ring sizes, please note that the rings are handcrafted and hence minor variations may occur.
