Carat Size Guide
How big is a carat?
Moissanite is sold by size, so carat here is an equivalent diamond-style size. Here are the approximate diameters of a round stone for the sizes we sell:
| Carat size | Diameter (round) |
|---|---|
| 0.5 ct | 5 mm |
| 1 ct | 6.5 mm |
| 2 ct | 8 mm |
| 3 ct | 9 mm |
| 5 ct | 11 mm |
Sizes are approximate and can vary slightly by design. Always check the stone size listed on the product page.
Tips for choosing
- Everyday wear: 0.5 to 1 ct sits low and neat.
- Engagement ring: 1 to 2 ct is the most popular range.
- Statement piece: 3 ct and up for a bold look.
