Platinum 2.25 Carat Lab-Grown 3-Stone Princess-Cut Diamond Engagement Ring

2 1/4 Carat Lab Grown 3 Stone Princess Cut Diamond Engagement Ring in Platinum

Our 2.25 carat lab grown 3 stone princess cut diamond engagement ring is built around a 1.75 carat princess cut center diamond, paired with two half moon lab grown diamonds totaling approx. 0.50 carats. The center stone shows a tight angular light pattern with clearly defined corners, giving the ring a structured modern look. The half moon sides follow the edges of the square center, adding a slight curve that keeps the design balanced without widening it too much. Platinum introduces a cooler tone and a noticeable weight to give the ring a more grounded feel on the hand. The 8.11mm top dimension provides presence while the 2.2mm shank and 1.7mm thickness keep the profile low and stable. Made in the USA with careful attention to alignment and finishing.

Defined Structure with Platinum Weight

Platinum changes how the ring feels both visually and physically. Its density adds a subtle weight, while its neutral tone allows the princess cut facets to appear sharper and more precise. The square center becomes the focal point, and the half moon side stones create a smooth transition into the band without breaking the symmetry.

Stable Build for Long Term Wear

The proportions are designed to support the size of the center stone without adding unnecessary bulk. Its shank provides strength at the base while 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 look. Over time, platinum develops a soft surface character rather than thinning, adding subtle texture with regular wear. Each ring is produced in the USA with attention to durability, alignment and finish.
