Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set solitaire invites you to choose a 10 x 5 mm marquise stone, its tapered silhouette evoking a quiet drama that complements the natural lines of the finger.

Crafted in warm 14K yellow gold, the mounting balances classic warmth with a refined profile. The slender prongs cradle the stone securely while allowing light to flood its facets, enhancing brilliance without excess height—ideal for everyday wear. The band’s smooth finish and gentle taper ensure comfort and ease, whether worn alone or paired with a wedding band.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every detail to meet exacting standards. The choice of a lab-grown diamond aligns with a commitment to ethical jewelry, offering clarity and beauty with a smaller environmental footprint.

This solitaire suits those who appreciate subtle elegance and a ring that feels as natural as it looks. Its low-profile setting slips easily beneath gloves and stacks gracefully with complementary bands, making it a versatile companion for daily life.
