1 3/4 Carat Lab-Grown 3-Stone Princess-Cut Diamond Engagement Ring in Platinum

Platinum 1.75 Carat Lab Grown 3 Stone Princess Cut Diamond Ring

Featuring a 1.40 carat lab grown princess cut center diamond, our 1 3/4 carat lab grown 3 stone diamond engagement ring in platinum is completed with two half moon lab grown diamonds totaling approx. 0.35 carats. The princess cut center shows a tight, angular light pattern with defined corners that give the stone a more structured look. The half moon sides follow the edges of the center to introduce a subtle curve that keeps the design balanced. Platinum adds a natural weight and cooler tone that allows the diamonds to appear more cohesive. With a 7.59mm top dimension, the ring holds a strong presence while remaining more than practical for daily wear, supported by a 2.2mm shank and 1.7mm thickness. Made in the USA with careful attention to proportion and finishing.

Defined Geometry with Platinum Weight

Platinum shifts the feel of this design by adding density without changing its size. The cool tone blends closely with the diamonds, making the edges of the princess cut appear more precise. The half moon side stones soften the transition into the band, keeping the overall structure clean without breaking the symmetry.

Structured Build for Long Term Wear

The proportions are set to keep the ring stable and comfortable. A shank supports the three stone layout while the thickness keeps the profile low on the finger. The four prong setting holds each stone secure while allowing light to move throughout the facets. Over time, platinum develops a soft surface texture rather than wearing down for subtle character with regular use. Each ring is produced in the USA with attention to alignment, durability and finish.
