A cremation diamond is a laboratory-grown diamond created with carbon prepared from cremated ashes. It can be kept as a loose stone or set in a ring, pendant or another suitable piece of jewellery.
Keeping a family story close
A cremation diamond can become a family heirloom: a stone worn now and passed to someone else later. It can also remain a private keepsake. What matters is the connection it represents to you, not whether it follows a particular tradition of remembrance.
What makes it a diamond?
Heart In Diamond prepares carbon from the ashes supplied for the order and uses HPHT equipment to grow a diamond crystal. The stone is then cut, polished and checked. It is a real laboratory-grown diamond, with the chemical and physical properties of diamond; it is not ash sealed inside a glass gem or metal setting. The manufacturing guide explains the technical stages in more detail.
Choosing the finished piece
You can first choose the diamond's carat range and colour, then decide whether to keep it loose or select a setting. Rings, pendants and earrings offer different ways to wear it. The colour guide shows possible tint ranges; the jewellery guide helps you compare settings. Individual stones may vary within the selected range.
Materials, timing and price
For a standard ashes order, we ask for 100 g of cremated ashes. Contact the New Zealand team if less is available before sending the material. Diamond creation usually takes around 90 days from receipt of suitable material. An optional jewellery setting, inscription or independent gemmological report may add time.
Diamond prices depend on carat range and colour; some cuts and extras are priced separately. Use the current New Zealand price guide to compare the options, then ask us to confirm the complete quotation for your order.
