The Marquise Solitaire is a 2.50 carat lab grown diamond engagement ring built around a single statement: let the stone do everything. No accent band, no side stones — just a clean marquise-cut center stone in a classic prong setting on 14K gold, with a gallery rail underneath for structural support and a flush-fit profile that pairs seamlessly with any wedding band. The marquise cut's elongated silhouette flatters the finger and creates a larger visual presence than a round diamond of the same carat weight. Available in yellow, white, or rose gold. For buyers searching for a marquise diamond solitaire engagement ring that's as wearable as it is striking — this is it. Handcrafted in NYC.
