Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set platinum mounting awaits a 9 x 4.5 mm marquise center, designed with delicate accent stones that frame the shape’s distinctive brilliance.

Handcrafted in our Williamsburg studio, the ring’s low-profile setting balances presence with everyday wearability. The platinum band is polished to a satiny finish, offering a cool, substantial feel that complements the diamond’s sharp geometry. Each accent is carefully set to enhance sparkle without overwhelming the marquise’s architectural elegance.

Our commitment to lab-grown diamonds ensures clarity and color with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

Ideal for those who appreciate refined artistry and a ring that sits comfortably beneath gloves or alongside stackable bands. The mounting’s proportions suit a slender hand, elongating the finger while maintaining a graceful silhouette.

Resizing is available to ensure a precise fit, crafted with the same attention to detail as the original design.
