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

Platinum 1 1/3 Carat Lab Grown 3 Stone Diamond Engagement Ring

Our 1 1/3 carat lab grown 3 stone diamond engagement ring centers on a 0.75 carat round lab grown diamond paired with two half moon side diamonds. The round center delivers a steady balanced sparkle while the half moon stones add a softer edge that frames the center without widening the profile too much. With VS clarity and F color, the diamonds maintain a bright, even appearance across the surface. Platinum brings a naturally cool tone and added density, giving the ring a more solid feel in hand. The 6.48mm top is supported by a 2.2mm shank and 1.7mm thickness, keeping the ring stable while sitting low and comfortable. Made in the USA with precise finishing and stone alignment.

Platinum Weight and Natural Finish

Platinum gives this ring a different presence compared to gold. It carries more weight, which makes the piece feel steady without increasing size. The metal also develops a soft surface over time rather than wearing down, which adds character with regular use. Its neutral tone blends directly with the diamonds, allowing the round center and curved side stones to appear more defined.

Compact Design with Practical Proportions

The dimensions are kept tight for everyday wear. The shank provides enough support for the three stone layout, while the 1.7mm thickness keeps the ring from feeling bulky. The four prong setting holds each diamond securely while still allowing light to pass through for a consistent look. Each ring is produced in the USA with attention to durability, alignment, and long term wear.
