0.5, 1 or 2 carat size: how big should the stone look?
4 min read · True Vow Rings
Carat is a diamond's weight. With cubic zirconia, shops use the same words to describe how big the stone looks next to a diamond of that weight. Our Six Prong Solitaire comes in 0.5, 1 and 2 carat sizes.
0.5 carat size: delicate
A small, neat stone that sits close to the finger. It suits slim fingers, people who work with their hands, and anyone who likes understated jewelry.
1 carat size: the classic
The size most people picture when they think of an engagement ring. Clearly visible across a table, but still easy to wear every day.
2 carat size: bold
A statement stone that catches the eye. It suits long fingers and people who love bold jewelry. It sits higher, so it may catch on knitwear and gloves.
How to choose
Look at their earrings and other jewelry: small studs point to 0.5 or 1 carat, bold pieces to 2 carat. If you can only guess, 1 carat is the safest choice.
Prefer a longer stone? An oval looks bigger for its size: see the Oval Cut Solitaire. Then check the band size in our ring size guide.

Questions and answers
What does "1 carat size" mean for a CZ ring?
It means the stone is cut to look like a 1 carat diamond. Cubic zirconia is heavier than diamond, so its actual weight is different.
Does a bigger stone change the ring size?
No. The band size stays the same whatever stone size you choose.
