Lab Grown Oval Diamonds
An oval is a round brilliant stretched along one axis. It keeps the brilliant faceting and most of the light return, but the elongated outline covers more of the finger, so an oval reads noticeably larger than a round of the same carat weight.
Use the filters above to narrow this lab grown oval inventory by carat, colour, clarity and cut. Prices move with live supply, so the stone you are looking at is the stone available today, and every one is sold loose with its grading report.
Choosing a oval diamond
Look at the length to width ratio, which most buyers prefer between 1.35 and 1.50, and check for a bow-tie, the dark band across the centre that appears when the facets are cut too shallow or too deep. A bow-tie is a cutting fault, not a grading one, so it will not appear on the certificate.
Lab grown or natural oval?
Every stone on this page is lab grown. If you want to price the same oval stone as a mined diamond, the same carat, colour, clarity and cut is listed in our natural oval diamonds, and the difference between the two is the clearest way to decide which you actually want. Both are real diamonds; the lab grown stone simply lets the same budget go further on size.
Other shapes and the full range
If you are still deciding on outline, compare this against lab grown pear shaped diamonds, lab grown marquise diamonds, lab grown round brilliant diamonds. The whole lab grown diamond inventory lists every shape side by side with the same filters.

Frequently asked questions
What should I look for in a oval diamond?
Look at the length to width ratio, which most buyers prefer between 1.35 and 1.50, and check for a bow-tie, the dark band across the centre that appears when the facets are cut too shallow or too deep. A bow-tie is a cutting fault, not a grading one, so it will not appear on the certificate.
Are lab grown oval diamonds real diamonds?
Yes. A lab grown diamond is the same carbon crystal as a mined one, with the same hardness and the same optical properties, and the two cannot be told apart by eye. Every stone here carries an independent grading report that names it as laboratory grown and a laser inscription on the girdle matching that report.
Can I have a oval diamond set into a ring?
Yes. Every lab grown oval diamond here is sold loose, so you choose the stone first and the setting second. Diamond Story sets loose stones into engagement rings, pendants and earrings in our Melbourne workshop, and we will advise on the setting that suits the shape you have chosen.
