About Gemstones

Moissanite is a conflict-free, hard-wearing, diamond-like gemstone. It sparkles like diamond does and is indistinguishable from diamond to the naked eye.

Moissanite is one of the most durable and scratch-resistant gemstones. It is rated as high as 9.25 on the Mohs hardness scale and is second only to diamond (rated 10). This means it can withstand daily wear and tear without being easily scratched or damaged. Hence, moissanite makes an excellent choice for earrings, whether worn every day or for special occasions.

How to Measure Your Ring Size

There are several simple ways to find your ring size.

Measuring the inside diameter of an existing ring

Option 1: Measure a Ring You Already Own

If you already have a ring that fits comfortably on the finger you plan to wear your new ring on, this is one of the easiest and most accurate methods.

  1. Place the ring on a ruler.
  2. Measure the inside diameter from one inner edge to the other, excluding the metal.
  3. Compare your measurement with the Inside Diameter column in our ring size chart above.
  4. If your measurement falls between two sizes, we recommend choosing the larger size.
Measuring a finger with a strip of paper or string

Option 2: Measure Your Finger

If you do not have a ring to measure, you can use a strip of paper, string or dental floss.

  1. Wrap it comfortably around the base of your finger.
  2. Mark the point where the ends overlap.
  3. Lay it flat and measure the length in millimetres using a ruler.
  4. Compare the measurement with the Circumference column in our ring size chart.
  5. If your measurement falls between two sizes, we recommend choosing the larger size.
