Lab-Grown Diamond Engagement Ring

Sunlight catches the broad facets of an 11 x 9 mm emerald-cut diamond, casting a glassy, architectural shimmer that draws the eye along its elongated planes. This platinum semi-set solitaire ring offers a refined foundation, crafted with meticulous artisan precision in our Williamsburg studio, ready to cradle your chosen center stone.

The band’s cool platinum gleams softly, its surface hand-polished to a satin finish that balances subtlety with strength. Designed with a low-profile setting in mind, it ensures daily wearability, slipping comfortably beneath gloves or alongside stackable bands without catching.

Each piece reflects our commitment to ethical jewelry: the emerald diamond you select will be lab-grown, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate architectural elegance paired with modern craftsmanship, especially flattering on longer fingers where the emerald shape elongates the hand.

Resizing is available to ensure a perfect fit, and our studio process includes careful inspection to maintain the integrity of the mounting. Lead times vary depending on stone selection, but we guide you through every step with transparency and care.
