Heart Lab Grown Diamond Necklace

The Satéur Destinée Diamond Necklace™ leads this collection of heart-shaped lab diamond pendants — a real, IGI-certified lab-grown diamond for a fraction of the mined price. Each necklace ships with free delivery, a lifetime guarantee, and the signature Satéur box, so a gift that looks like a major occasion arrives feeling like one too.

The pendants are set in solid 18K gold, not plating, with the chain crafted to match. The stone is an IGI-certified lab-grown diamond, grown with the same carbon structure as a mined diamond and documented by the same independent laboratory. Solid metal and real certification are what let a diamond heart rest at the throat at a price mined stones cannot approach.

The diamond is a genuine diamond — Mohs 10, the hardest material there is — graded to D–E colour, Excellent cut, and VS clarity. Held in a heart silhouette, that near-colourless brilliance catches the light from across a room with the same flawless sparkle a mined stone returns, with no compromise in the gem itself.

The collection moves across the heart-shaped pendant in white gold and warm yellow gold, in fine and statement carat weights, on delicate and substantial chains, so you can choose a quiet everyday heart or a piece built for an anniversary or bridal moment. The grid below shows every piece.
