This ring has two things going on, and both are worth noticing. First, the stone: a marquise, graded E color and VS clarity. The marquise is one of the oldest fancy shapes: long, pointed at both ends, with real vintage character. It elongates the finger and reads larger than a round of the same weight because the shape spreads the carat across a longer surface.

Second, the band: it's an antique-style flexible chain, made of small linked sections rather than one rigid hoop. That articulation lets it move and settle with your finger, and it gives the whole piece an old, almost regal feeling. It's an unusual construction you don't see on most modern rings.

The metal is solid 18K yellow gold, 75% gold, a deep warm yellow that suits the antique look. The warm gold against the colorless marquise is a classic vintage pairing.

On the diamond: lab grown means it was created in a controlled facility rather than mined. It's the same carbon crystal as a mined diamond: same hardness, same fire, same way it throws light. A real diamond on a band with genuine old-world character.

FAQ
Is this a real diamond?

Yes. It's a lab grown diamond, the same carbon crystal as a mined diamond, chemically and optically identical. Not a simulant like cubic zirconia or moissanite.

What is a flexible-chain band?

The band is built from small linked sections instead of one rigid hoop, so it articulates and moves with your finger. It gives the ring an antique, distinctive feeling.

Why a marquise cut?

The long, pointed shape elongates the finger and reads larger than a round of the same carat weight. It has a strong vintage character.

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.
