Lab-Grown Diamond Engagement Ring

Imagine the moment light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a sleek, modern three-stone setting. This semi-set platinum band awaits your choice of an 8 x 4 mm center stone, designed to showcase the marquise’s distinctive blend of drama and refinement.

Crafted in platinum for enduring strength and a cool, luminous finish, the mounting features a low-profile design that rests comfortably against the finger. Each prong is precisely shaped to secure the stone while maintaining an open structure that maximizes light play and sparkle. The three-stone arrangement balances architectural clarity with confident minimalism, ideal for daily wear without excess bulk.

Our lab-grown diamonds offer the same optical brilliance as mined stones, with a significantly reduced environmental footprint—an ethical choice embedded in every facet.

This ring suits those who appreciate clean lines and a statement that is both bold and refined. Its slender shank and low profile make it glove-friendly and stackable with complementary bands, while the marquise shape visually elongates the finger for an elegant silhouette.
