Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that hints at quiet drama. This semi-set engagement ring invites you to select a 10 x 5 mm marquise stone, whose pointed ends and curved sides create a striking balance of boldness and elegance.

Crafted from 14K white gold, the mounting is shaped with artisan precision in our Williamsburg studio. The slender prongs cradle the stone securely while maintaining a low profile that sits comfortably against the finger. The band’s smooth finish and subtle taper ensure it layers effortlessly with other rings or stands alone with refined simplicity.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and brilliance without compromise. This choice supports sustainability while honoring the timeless allure of fine craftsmanship.

Designed for those who appreciate a blend of modern geometry and everyday wearability, this solitaire setting suits hands that favor sleek, elongated forms. Its low profile and comfort fit make it ideal for daily life, whether paired with a wedding band or worn solo.

Should you need resizing or wish to explore stone options, our Brooklyn studio offers personalized guidance with attentive care and reasonable lead times.
