Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set solitaire invites you to select a center stone that will become the singular focus of a refined two-tone band, where warm 18k yellow and 18k yellow and platinum meets cool 18k yellow and platinum in a subtle contrast.

Crafted in Williamsburg, the band’s low-profile setting ensures the ring sits close to the finger, offering both comfort and a sleek line that complements the marquise’s dramatic shape. The fixed two-tone design balances the vintage romance of 18k yellow and 18k yellow and platinum with the modern clarity of 18k yellow and platinum, finished with meticulous hand polishing and inspection to meet daily wear demands.

Each lab-grown diamond option reflects a commitment to ethical sourcing and environmental mindfulness, aligning with a sustainable approach to fine jewelry.

This solitaire suits those who appreciate a statement piece that remains understated in its wearability—ideal for slender fingers or as a striking complement to stackable bands. Its low profile and smooth edges make it glove-friendly and easy to wear every day.

Should you wish to adjust the band size, resizing is available with care to preserve the integrity of the two-tone finish.
