Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a slender, graceful sparkle that seems to dance along the finger. This semi-set solitaire ring invites you to choose a 9 x 4.5 mm marquise center, its pointed ends lending a quiet drama and elongating the hand with refined elegance.

Crafted in 14K white gold, the mounting balances a delicate presence with sturdy comfort. The slender prongs cradle the stone securely while allowing maximum light to enter, enhancing the diamond’s signature brilliance. The band’s smooth finish and moderate width ensure a comfortable fit for daily wear, while its low-profile setting slips easily beneath gloves or alongside stackable bands.

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

This solitaire suits those who appreciate subtle sophistication and a touch of vintage-inspired romance, especially on slender fingers or those seeking an elongated effect. The semi-set design allows you to select a marquise diamond that speaks personally, making the ring uniquely yours.

Resizing is available to ensure the perfect fit, and our team is happy to guide you through care and customization options. Lead times vary slightly depending on stone selection but are communicated clearly at consultation.
