Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a slender finger crowned with an 8 x 4 mm marquise diamond, its tapered points catching light like whispered promises. This semi-set halo ring in polished sterling silver frames the center stone with a delicate circle of smaller gems, enhancing its elongated silhouette with a subtle glow.

Crafted in Williamsburg, the band’s smooth finish and modest profile ensure comfort for everyday wear, while the halo setting adds a refined sparkle without overwhelming the hand. Each piece is meticulously inspected to balance durability with elegance, designed to sit low enough for glove-friendly ease yet high enough to catch the eye.

Our lab-grown diamonds offer a clarity and brilliance born from sustainable practices, reflecting a commitment to ethical jewelry without compromise. The marquise shape lends a graceful drama, elongating the finger and evoking a quiet confidence suited to those who appreciate both tradition and modernity.

Whether worn solo or stacked with complementary bands, this ring adapts seamlessly to a variety of personal styles. Resizing is available to ensure a precise fit, with care instructions provided to maintain its luminous finish.
