Heart Lab Diamond Engagement Rings - direct from the makers.

Romantic, symbolic, and impossible to overlook - a heart shaped lab grown diamond ring is the ultimate expression of love. With its perfectly balanced curves and a precision-cut cleft, the heart shape radiates both sentiment and sophistication, making it one of the most personal choices you can make for your proposal.

The Meaning Behind the Heart Cut

A heart-shaped diamond is more than just a design - it's a declaration. At Temple and Grace, we create heart engagement rings using ethically grown lab diamonds that match the brilliance and durability of mined stones, yet are far more sustainable. This means your love story can shine just as brightly, without compromise.

Crafted Around Your Style

Our heart-shaped diamond rings are available in:

  • Elegant solitaires for timeless romance
  • Halo designs for a captivating, light-filled sparkle
  • Bespoke creations tailored to your vision, with your choice of metal and setting

Each ring is handcrafted in 9K, 14K, 18K yellow, white, or rose gold, or platinum, ensuring comfort, durability, and heirloom quality.
