Oval Lab Grown Diamond Rings

The oval is the most-worn fancy shape for a practical reason: its brilliance comes close to a round, but the elongated outline spreads the carat across more of the finger, so an oval reads larger than a round of the same weight and makes the finger look longer doing it.

Every oval here is a lab grown diamond — the same carbon crystal as a mined stone, grown in a controlled facility. Most settings can be ordered across several carat weights and metals; each ring is made to order in your US size.
