Platinum 2.75 Carat Lab-Grown 3-Stone Diamond Engagement Ring

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

Formed around a 2 carat round lab grown center diamond, our 2.75 carat lab grown 3 stone diamond engagement ring is completed with two half moon lab grown diamonds totaling approx. 0.75 carats. The round center produces a steady well-defined brilliance while the half moon sides create a natural taper that keeps the overall shape controlled. With VS clarity and F color, the diamonds show a bright, even surface with minimal visual noise. Platinum adds a noticeable weight and a cooler tone, giving the ring a more grounded feel compared to gold. The 8.26mm top is supported by a 2.2mm shank and 1.7mm thickness, keeping the profile low and balanced on the hand. Made in the USA with attention to structure and finish.

Density and Definition in Platinum

Platinum gives the ring a different presence on the hand. It carries more natural density, which adds a sense of stability without increasing size. Its cool tone blends directly with the diamonds, allowing the round center to appear sharper and the half moon sides to transition more subtly into the band. The overall look feels cohesive and structured without excess detail.

Low Profile Build with Long Term Wear in Mind

The proportions are designed to support the center stone without adding unnecessary height. Its shank provides strength, while the 1.7mm thickness keeps the ring sitting close to the finger. The four prong setting allows light to enter the stones while maintaining a secure hold. Platinum also wears differently over time, developing a soft surface character instead of thinning. Each ring is produced in the USA with consistent finishing and careful alignment. Also available in various metals and styles, shown below.
