1/3 Carat Round Diamond Engagement Ring in Platinum

Platinum 0.33 Carat Round Diamond Ring

Crafted in solid polished platinum, our 1/3 Carat Diamond Engagement Ring is centered on a 4.4mm natural round diamond selected for its balanced proportions and brilliance. The 0.33 carat center stone is encircled by 16 round accent diamonds that form a clean under halo while 22 additional round diamonds continue along the band, bringing the total diamond weight to approx. 3/4 CTW. With SI2–3 clarity and a G–H color range, the diamonds display a bright natural tone that stands in clear contrast against the cool dense surface of polished platinum.

Platinum Setting and Diamond Definition

The round center diamond is secured in a 4-prong setting that allows light to enter from multiple angles while maintaining a low stable profile. The under halo follows an even circular pattern to add definition without competing with the center stone. Along the shank, the round diamonds are evenly spaced to create a smooth line of light that complements the weight and structure of the platinum band.

Weight, Comfort, and Everyday Wear

The natural density of platinum gives this ring a noticeable sense of substance while remaining comfortable for daily wear. A slim band keeps the fit balanced and secure, supporting the center stone and halo without feeling heavy on the hand. Built with natural diamonds and a solid metal foundation, this ring is designed to hold both its form and meaning through years of regular use.
