HOW TO FIND YOUR RING SIZE

There are two simple ways to determine your ring size:
• Measure one of your rings. Choose a ring you wear regularly and measure its inner diameter (mm). Compare it with our size chart to find your correct size.
• Measure your finger circumference. Use a piece of string or a strip of paper, wrap it around your finger, and mark where the ends meet. Measure the length (circumference) and check our chart to find your ring size. If you have any questions, email us at info@oonacollections.com and we’ll be happy to assist you personally.
