Diamond Heart Necklace

At Satéur, a diamond heart necklace starts at around $88 — roughly 1% of the price of a mined-diamond equivalent, which typically sells for $1,500–$10,000 depending on carat weight. Each stone is a Satéur Gems® — our trademarked diamond simulant — graded D–E colour with an Excellent cut, delivering the naked-eye appearance of a flawless diamond. The signature Satéur box, free worldwide delivery and a lifetime guarantee are included with every order.

Every diamond heart pendant in the collection is hand-set in nickel-free 925 sterling silver, finished in a lasting 18k gold — available in white gold, yellow gold and rose gold. Unlike a thin gold-plated piece that wears through at the bail or clasp within a season, the 18k gold finish is sealed for enduring daily wear and is safe for sensitive skin. The necklace sterling silver core keeps the piece lightweight while the gold finish maintains the fine-jewellery look.

Satéur Gems® are extremely durable, built for heirloom longevity — not just occasional wear. They deliver the clean, white brilliance of a flawless diamond, a sparkle that catches light at every angle and in every setting. Unlike pink sapphire diamond combinations sold at mid-market retail, or sapphire-accented styles that vary season to season, our diamond heart collection is centred on the one stone that reads as a flawless diamond without the price.

The range covers a spectrum of heart pendant sizes and carat weights, from delicate solitaire drops that sit at the collarbone on a 16" pendant necklace chain, to fuller pavé diamond heart pendant designs in larger carat settings for those who want impact. The chain is adjustable, and every pendant sterling silver piece is available across all three metal finishes. A heart-shaped diamond heart pendant in yellow gold finish reads like a boutique window at a fraction of the price; the white-gold version is particularly sought after for engagements and anniversaries.
