Popular Shapes for Lab-Grown Diamonds
Lab-grown diamonds are cut in all the same shapes as natural diamonds, offering something for every style.
The round brilliant cut is the most popular because it delivers the most sparkle, but fancy shapes like oval, cushion, and pear are also highly sought after for their individuality and elegance. Each shape has its own character and appeal, making the choice highly personal.
Key shape highlights:
- Round Brilliant: Maximum brilliance and sparkle.
- Oval: Elegant, elongating effect on the finger.
