Diamond and Gemstone Heart Pendants and Necklaces

Our heart pendants and necklaces celebrate the universal symbol of love, offering a timeless way to express affection. From understated designs for everyday wear to more opulent statement pieces, heart pendants and necklaces in this collection are crafted to suit a range of styles and occasions.

Each heart pendant and necklace is consciously crafted from recycled precious metals, including white gold, yellow gold, silver, and gold vermeil. Designs are primarily set with brilliant white diamonds that are either natural or lab-grown. Our natural diamonds are conflict-free and responsibly sourced in line with the UN-backed Kimberley Process, while our lab-grown diamonds are chemically and optically identical, delivering the same beauty, brilliance, and lasting quality.

Beyond diamonds, the collection of heart pendants and necklaces also features vivid gemstones such as emerald, sapphire, and ruby. Many designs use pavé or classic claw settings to enhance light return and highlight the heart motif.

Explore the collection and discover heart pendants and necklaces designed to symbolise meaningful connections and celebrate your personal story.
