Lab-Grown Diamond Engagement Ring

Imagine the delicate silhouette of a marquise diamond, its tapered points drawing the eye along the length of your finger like a whispered promise. This semi-set platinum halo ring offers a refined stage for a 10 x 5 mm marquise center stone, ready to be chosen and cherished.

Crafted in cool, polished platinum, the mounting balances strength with subtlety, its low-profile halo setting embracing the center stone without overwhelming. The band’s smooth comfort fit ensures it wears effortlessly through daily moments, while the halo’s delicate pavé adds a gentle shimmer that catches light with every movement.

Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet artistry. The lab-grown diamond you select will carry the clarity and brilliance of natural stones, with a fraction of the environmental impact.

This design suits those who appreciate elegant elongation and a touch of vintage romance, especially flattering on slender fingers or when paired with stackable bands. Its low profile makes it glove-friendly and ideal for everyday wear.
