Sunlight catches the elongated silhouette of a marquise diamond, casting a subtle glow that dances along the fingers. This three-stone semi-set engagement ring features an 18K yellow gold band, hand-shaped and polished in our Williamsburg studio to a smooth, comfortable fit.

The marquise center stone, measuring 10 by 5 millimeters, offers a striking balance of drama and elegance with its tapered points and brilliant facets. Flanking side stones cradle the center, enhancing its architectural presence while maintaining a low-profile setting that slips easily beneath gloves or daily wear.

Each ring is crafted with precision, from the secure prong setting to the meticulous finishing that ensures durability and comfort. Our lab-grown diamonds bring clarity and sparkle without the environmental cost, reflecting a commitment to ethical jewelry that aligns with modern values.

Designed for those who appreciate bold geometry paired with artisanal detail, this ring suits hands that welcome statement pieces yet demand everyday practicality. Its semi-set nature invites you to select a center stone that resonates personally, making the design truly your own.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly into your life.
