Engagement Collection

At Heidi and Hart, we’re all about celebrating love your way, with diamonds you can wear every day.

Founded by Heidi and Ben, Heidi & Hart embodies a shared vision of crafting heirloom-quality jewellery that transcends mere adornment.

GIA Certified

At Heidi & Hart, we source diamonds that meet the highest standards and value transparency at every step. Many of our pieces feature GIA-certified diamonds, assessed by the Gemological Institute of America, the world’s leading authority in diamond grading.

A GIA certificate confirms your diamond’s quality and authenticity, covering the 4Cs: cut, clarity, colour and carat weight.

Whether you're selecting a certified stone for a bespoke design or remodelling a piece you already love, we’ll guide you toward a diamond that feels right for you, with confidence and clarity.
