2 3/4 Carat Lab-Grown 3-Stone Princess-Cut Diamond Engagement Ring in Platinum

Platinum 2.75 Carat Lab Grown 3 Stone Princess Cut Diamond Engagement Ring

Anchored by a 2.15 carat lab grown princess cut center diamond, our 2 3/4 carat lab grown 3 stone diamond engagement ring is finished with two half moon lab grown diamonds totaling approximately 0.60 carats. The center stone shows a tight, angular light pattern with defined corners that give it a structured, modern look. The half moon side stones follow the edges of the center, introducing a slight curve that keeps the design balanced and controlled. Platinum adds a natural weight and a cool tone, giving the ring a more solid presence while allowing the diamonds to appear distinct and cohesive. With an 8.63mm 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. Made in the USA with attention to alignment and finishing.

Defined Edges with Platinum Density

Platinum changes how the ring reads both visually and physically. Its density adds weight without increasing size, while its neutral tone allows the princess cut facets to appear more precise. The square center becomes the focal point, and the half moon sides create a smooth transition into the band without interrupting the symmetry.

Built for Long Term Stability

The proportions are designed to support the center stone while keeping the ring comfortable. Its shank provides strength and the 1.7mm thickness keeps the profile low on the finger. The four prong setting secures each diamond while allowing light to pass through for a consistent look. 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 finish.
