An oval is one of the most flattering shapes you can put on a hand. It's longer than a round, so it stretches the finger and reads bigger for the same carat weight. The center is graded E color and VS clarity: colorless and eye-clean, with the soft brilliance that makes ovals a perennial favorite for engagement rings. Choose your center weight (1ct, 2ct,  3ct, 4ct or 5ct) for how much presence you want.

Flanking it are two side stones, scaled to the center, that carry the eye outward and fill the top of the ring. The three-stone layout is one of the oldest engagement designs for a reason: it gives a single center stone presence without going to a big halo or a wide band.

The metal is Platinum 950, which is 95% platinum, naturally white and dense. It won't yellow, and it never needs the re-plating that white gold does to stay bright. The cool white sits well against the colorless oval.

On the diamonds: lab grown means created in a controlled facility rather than mined. Same carbon crystal, same hardness, same fire as a mined stone. A real diamond, in a ring meant to be worn every day.

FAQ
Is this a real diamond?

Yes. All three stones are lab grown diamonds, the same carbon crystal as a mined diamond, chemically and optically identical. Not a simulant like cubic zirconia or moissanite.

Why is an oval a good engagement choice?

It reads larger than a round of the same carat weight and elongates the finger, while keeping the brilliant sparkle of a round cut.

Why platinum?

Platinum is naturally white and never needs re-plating, and it's dense enough to hold stones securely over decades of daily wear.

Does it come with a certificate?

Lab grown diamonds 1 carat and above are IGI-certified; you can verify the report online.

Can I choose my ring size?

Yes, select your US size at checkout. Not sure of your size? See our ring size guide.
