At Black Jack®, we specialize in transforming the essence of your loved one — whether human or pet — into a certified lab-grown diamond or symbolically infused gemstone. Using advanced carbon science and globally accepted HPHT methods, we preserve memories as precious stones that last forever.
How We Transform Carbon into Diamonds & Gemstones
We extract pure carbon from hair or cremation ashes, purify it, and convert it into graphite. This graphite is then used in a High Pressure High Temperature (HPHT) machine that mimics Earth’s natural diamond-forming conditions. Over weeks, a real, certified diamond is grown — infused with your loved one’s carbon.
Accepted Carbon Sources
-
Human Hair – from scalp, beard, or body (clean and dry)
-
Cremation Ashes – minimum 300 grams required
-
Pets – Dog, Cat, Rabbit, Horse (hair or ashes)
