How cremation diamonds

Are made

At Heart In Diamond, technologies are mixed with a generous portion of love and dedication. The production process evolves around carbon: once we extract carbon from hair or ashes, we create the growing foundation of the future diamond.

The next step of manufacturing the diamond is placing it into the heart of a HPHT (High Pressure High Temperature) Machine. This machine shapes the future size and color of your diamond. Once the growing process is complete, the diamond gets cut, polished, and certified in accordance with the highest industry standards.

The package with the pendant arrived right on time. It's beautiful! From now on I'll wear him close to my heart.
I don't know how to thank you for everything. Whenever I know somebody with the idea of getting a diamond I'll make sure to mention your name.

Just wanted to touch base & let you know I received the ring this morning. It's absolutely gorgeous! It's more beautiful than I could have imagined. My coworkers & I were all in tears. I just think what you guys do is so amazing! What a beautiful tribute to our loved ones, and it's so special to be able to keep them with us at all times.
Thank you so much for your help through this whole process.

Lucille, UK

I can’t thank Heart In Diamond enough for the stunning ring setting and my best friend Bugsy. (My old school friend).
Thirty one years we shared tears, laughter, love and the odd falling out. Now thank you to all your team for the experience of dealing with a professional company and creating an amazing white diamond now nicknamed Bugsy.


Ruth, UK

I contacted Heart in Diamond as I wanted a diamond made from my late husband's ashes. I have to say I was apprehensive as I had not heard of the company, nor of the process really.
However, my fears were totally unfounded as from the very first contact, Heart in Diamond has shown that there is a company with integrity, and who care at a time when you need it most. I would have no hesitation in recommending Heart in Diamond.
