Heidi & Hart Fine Jewellery

Ready To Wear

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.
