Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the length of the finger. This semi-set solitaire ring invites you to select a center stone measuring approximately 9 by 4.5 millimeters, a shape known for its tapered elegance and ability to visually lengthen the hand.

Crafted from warm 14K rose gold, the band is shaped and polished in our Williamsburg studio to a gentle comfort fit, ensuring it rests lightly for daily wear. The setting’s minimalist prongs cradle the stone securely while maintaining a low profile that slips easily beneath gloves or stacked rings. Each piece is hand-finished and inspected to meet exacting standards of balance and durability.

Our diamonds are lab-grown, offering a clear, sustainable alternative that reflects a commitment to ethical jewelry without compromise on brilliance or clarity.

This ring suits those who appreciate refined geometry paired with artisan craftsmanship—ideal for slender fingers or anyone seeking a statement piece that remains understated in its wearability. The semi-set design allows you to personalize your engagement ring with a stone that speaks to your story.
