SPINELLI KILCOLLIN Petunia set of three sterling silver and 18-karat gold diamond rings

• US sizing

We advise that you measure the size of your finger rather than the size of your ring. 1. Wrap a length of string or ribbon around the base of your finger. To ensure the ring fits comfortably, we suggest measuring your knuckle as well. Select a size that will slide on and off your finger easily. 2. With a pen, mark the point on the string where the ends meet. 3. Measure the string in millimeters with a ruler. 4. Choose the closest measurement to the chart below to identify your ring size.
