Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc that feels both bold and intimate. This semi-set three-stone engagement ring foundation, crafted in 14K white gold, awaits your choice of center stone to complete its story.

Each band is shaped and polished in our Williamsburg studio, where the smooth comfort fit and gently tapered shoulders ensure the ring sits low and secure for everyday wear. The three-stone setting balances architectural precision with artisan detail, designed to showcase the marquise’s dramatic length alongside two complementary side stones.

Our commitment to ethical jewelry is reflected in the option for a lab-grown diamond center, offering clarity and brilliance with a smaller environmental footprint. The 14K white gold finish is carefully inspected for durability and shine, marrying modern craftsmanship with sustainable values.

This ring suits those who appreciate a statement piece that remains refined and wearable—its low-profile setting slips easily beneath gloves or alongside stackable bands. The 9 x 4.5 mm marquise shape visually elongates the finger, ideal for hands seeking a slender, elegant silhouette.

Should you wish to adjust sizing, our in-studio team provides expert resizing to ensure a perfect fit without compromising the ring’s integrity. Typical lead times for custom center stones and final assembly are communicated clearly during consultation.
