Platinum 2 1/4 Carat Lab-Grown 3-Stone Oval Diamond Engagement Ring

2.25 Carat Lab Grown 3 Stone Oval Diamond Engagement Ring in Platinum

Centered with a 1.80 carat lab grown oval diamond, our 2 1/4 carat lab grown 3 stone oval diamond engagement ring is finished with two half moon lab grown diamonds totaling approx. 0.45 carats. The oval center stretches across the finger with a smooth, continuous light pattern, creating a softer and more elongated look compared to square cuts. The half moon side stones follow that curve, keeping the transition into the band clean and controlled. Platinum adds a cool tone and a noticeable weight to give the ring a more grounded presence while allowing the diamonds to always appear crisp and cohesive. With a 9.37mm top dimension, the ring stands out without feeling oversized, supported by a 2.2mm shank and 1.7mm thickness that keep it low and stable.

Elongated Form with Platinum Weight

Platinum changes how the ring feels both visually and physically. Its density adds weight without increasing size, while its neutral tone allows the oval center to appear more defined. The soft curve of the center stone is echoed by the half moon sides, creating a smooth, uninterrupted flow into the band.

Structured for Stability and Long Term Wear

The proportions are set to support the center stone while maintaining comfort. Its shank provides strength and the 1.7mm thickness keeps the ring sitting close to the finger. The four prong setting secures each diamond while allowing light to pass through for a consistent finish. Over time, platinum develops a soft surface character rather than wearing down, adding subtle texture with regular use. Each ring is produced in the USA with attention to durability, alignment and polish.
