If additional carbon is required, we use compatible high-purity carbon appropriate for diamond growth.

We typically ask for:

• 1/2 cup of ashes; or
• 1 cup of lightly packed hair.

If you have less than that, contact us. A small amount can still go a long way, and we can review what you have before confirming whether it is enough.

Yes. All three sources—ashes, hair, and fur—can contain enough carbon to grow a diamond, but the concentration varies significantly by material type.

Typical carbon content ranges:

Cremated remains (ashes): ~1–4% carbon After cremation, most organic material is burned off, leaving primarily mineral content (calcium, phosphates, etc.) with a small amount of remaining carbon.

• Even with lower carbon content, only a small amount of purified carbon is needed to grow a diamond. This is why a half cup of ashes or a cup of hair is generally more than sufficient.
  

Hair (human): ~40–50% carbon
Hair is primarily composed of keratin, a carbon-rich protein, making it a strong and reliable carbon source.

Fur (animal): ~40–50% carbon
Similar to human hair, animal fur is also keratin-based and contains a high percentage of carbon.

No, not directly. A small amount of ashes or hair can often provide enough carbon for diamond growth. The final diamond size is determined more by the selected carat weight, growth process, and production requirements than by the amount of ashes submitted.

Yes. Hair can be used instead of ashes, or in combination with ashes.

Yes. Ashes do not expire. Hair can also be used even if it has been kept for many years.

Yes, in many cases. Combining ashes can be a meaningful way to honor more than one person in a single diamond. We can discuss this during the order process.

Yes. Because only a small amount of carbon is needed for diamond growth, it may be possible to create multiple diamonds from the same sample. This can be helpful for families who want several pieces made from the same source material.

Yes, some meaningful natural materials may be included if they are dry and appropriate for carbon extraction. Examples may include dried flowers, cotton clothing, or handwritten letters.

No. Dirt and sand do not typically provide the right carbon source for diamond growth. If you want to include something connected to a place, dried flowers, grass, or another organic material from that location may be a better option.

Diamond Cremation diamonds can be grown in a range of carat sizes 0.25 to 5+ carats. Larger diamonds are more complex to grow and may require additional time.

Available colors may include colorless, yellow, blue, black, red, green, and other specialty colors.

Some colors are achieved during the growth process, while others may require additional treatment afterward.

Diamond color depends on trace elements, growth conditions, and post-growth treatment. Blue and yellow tones are commonly associated with specific elements introduced during growth. Other colors may require additional treatment after the fact like irradiation.

Yes, options include round, oval, emerald, cushion, princess, pear, radiant, asscher, and heart. We can help you select a cut that fits your preferred style, jewelry setting, and diamond size.

We will do our best to accommodate changes, but it depends on where your diamond is in the process. Some choices become fixed once carbon preparation, growth, cutting, or color treatment has begun.

Please contact us as soon as possible if you want to make a change.

Diamond creation typically takes 4–6 months. Larger diamonds or specialty colors may take longer. Jewlery setting can take up to another few weeks.

Growing a custom diamond requires multiple technical steps: carbon extraction, preparation, diamond growth, quality checks, cutting, polishing, grading, and final delivery or jewelry setting. Each diamond is custom-grown, so timelines vary based on the specifications selected.

If the process takes longer than expected, we will keep you updated. Larger diamonds, specialty colors, or regrowths may require additional time. Our priority is delivering a diamond that meets the agreed quality standards.

Yes. We can create a diamond using ashes or fur from a beloved pet.

A Living Diamond is a diamond created from hair collected from someone who is still living. It can be used to celebrate a milestone, create a family heirloom, or preserve a meaningful connection during life rather than after loss.

Living Diamonds and memorial diamonds are created through the same general process. The main difference is the source material coming from hair vs ashes.
