Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 7 x 7 mm square diamond, its facets unfolding like a quiet promise. This five-stone semi-set engagement ring foundation in 18K yellow gold invites your choice of center stone, framing it with four delicate side gems that catch light from every angle.

Crafted with a low-profile setting, the band’s smooth finish and subtle curvature ensure a comfortable fit for daily wear. Each prong is meticulously shaped and polished in our Williamsburg studio, balancing secure hold with refined elegance.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance born of sustainable innovation, reflecting a modern approach to ethical jewelry.

The warm glow of yellow gold complements a variety of skin tones and lends a classic warmth to the geometric precision of the square shape. Its slender silhouette pairs beautifully with stacking bands or stands confidently alone, designed for hands that appreciate both artistry and ease.

Should you need resizing, our in-house artisans adjust the band with care to maintain its seamless profile. Typical lead times allow for thoughtful customization without rush.
