Our process

A Heart In Diamond personal diamond passes through a documented sequence from order registration and material analysis to HPHT growth, cutting, certification and delivery.

1. Order placement

The process starts with discussing your options and placing the order. Once the details are confirmed, we issue an individual Heart In Diamond order ID.

2. Sample receipt and registration

The supplied ashes, hair or fur are received and registered against the order so the source material remains linked to the customer reference.

3. Sample analysis and carbon preparation

The laboratory analyses the sample, prepares its carbon and combines it with the diamond-growing foundation from which the crystalline structure will grow.

4. HPHT diamond growth

The prepared carbon source is placed in HPHT equipment, where controlled high pressure and high temperature create the conditions required for diamond crystal growth. Creating the diamond usually takes around 90 days from receipt of suitable material.

5. Cutting and polishing

After growth, specialists cut and polish the diamond in accordance with the agreed option and the usable crystal produced.

6. Quality control and grading

The cut and polished diamond passes the applicable quality-control and grading checks.

7. Certification

Every personal diamond receives a Heart In Diamond Certificate of Authenticity, including a breakdown of its chemical composition. Optional AnchorCert certification can be arranged if selected.

8. Optional jewellery setting

If jewellery has been selected, the personal diamond is fitted to the compatible ring, pendant or other setting after the loose stone has completed its checks.

9. Delivery and tracking

The completed loose diamond or jewellery order is prepared for authorised delivery. Jewellery, certification, engraving and other selected options can add to the overall schedule, and the UK team will keep you updated.

Required materials

For a standard order, we request either of the following amounts regardless of the diamond size. If you have less, contact the UK team before sending anything so the sample can be assessed.
