1 cup of ashes, hair or other material is needed to grow four or more diamonds

Where will my Eterneva Diamond be grown?

SCI Eterneva Memorial Diamonds will be grown in our facility in Kerrville, Texas.  We welcome our customers and funeral directors to come and tour our facility to see our process in person.

The entire process takes 12 months (for diamond orders of 1 carat or less)

For 1.5 to 2 carat diamonds or diamonds requiring coloration (red, green, black, pink) 12-16 months.

Is there enough carbon in ashes to create a Diamond?

Yes, there is more than enough carbon in ashes to grow a Diamond. We work closely with TDI Brooks International, a world-renowned carbon testing and forensic organization, to test the carbon contents in cremated remains, hair, and aquamation ashes. 

The cremated remains sample contained 3.28% carbon, the hair sample to contained 36.66% carbon, and the aquamation sample to contained 16.91% carbon.

Where can I read Eterneva reviews or testimonials?

You can find Eterneva reviews just about anywhere! Eterneva reviews are on Facebook and Google, TrustPilot, The Cremation Institute, and even on our Instagram. You can read a full collection of Eterneva reviews here, or watch a collection of Eterneva video reviews here.

In fact, here is one from a recent customer:

“This whole process is about so much more than the Diamond. I’m learning how to grieve better with you. When my friend lost her dog months after I lost my beloved Fritz, I knew how to sit with her in the pain, how to help her collect the things she’d want to keep, and how to be a better friend in her grieving moments. I can’t wait for my Fritz’s Diamond to come home, and I am already so much more able to lean in to loss and embrace legacy projects, memorials and all the emotions that come with it. Thank you!” –– Grace Halverson, Fritz’s Mom

Is there carbon in hair?

Yes, there is a lot of carbon in hair! B&B Labs, a leading analytical chemistry lab in College Station, found that hair contains upwards of 30% carbon. We only need a healthy handful of hair to extract enough personal carbon to grow a Diamond.

Is there carbon left in ashes after cremation?

Yes, there is absolutely carbon left in ashes. B&B Labs, a leading analytical chemistry lab in College Station, found that cremated remains contain 1-4% carbon depending on the age of the person, their diet, and other factors. 

Eterneva is the only memorial Diamond company to offer third-party ashes analysis for customers curious about their loved one's carbon makeup.

Instead of cremated ashes, can I use other sources to create a Diamond?

You are able to include other sources of carbon to supplement with anything that has significance to you, which could include (but is not limited to) clippings of hair, cotton clothing, dried flowers, written letters. We ask that you make sure anything you send is completely dry.

How is a Diamond made from ashes?

The ashes to Diamond process includes multiple steps.

  1. The ashes will be purified to extract the remaining 1-4% of carbon within them. This carbon will be used to grow your memorial Diamond.  You’ll receive videos of us transferring your loved one’s ashes, as well as us opening up the purification crucible for the first time to see the carbon within.
  2. We combine your loved one’s carbon, a microscopic Diamond seed, and generic carbon into a growth cell. This Diamond seed gives a site for the carbon to bond to, similar to how a piece of sand helps a pearl form around it.
  3. The Diamond growth cell will be placed in a High Pressure High Temperature (HPHT) machine and grown in isolation.
  4. We harvest the raw Diamond out of the growth cell to see the resulting raw Diamond and do a quality assessment. We'll scan the Diamond (like an x-ray!) to identify the placement of imperfections an
  5. The rough Diamond will be cut by hand by master Diamond cutters and colored to the specification of the customer. The timing will vary depending on the cut and color of the Diamond.
  6. The Diamond will be graded by our own in-house GIA certified Diamond Grader. The Gemological Institute of America is one of the top Diamond grading organizations in the world. The report card on your Diamond’s carat size, cut, color, and clarity will be sent home with the Diamond.
  7. A Homecoming will be scheduled by your Funeral Director. 
How does Eterneva keep track of my Customer's Loved One's ashes

Chain of custody is of the utmost importance, and we prioritize our logistics above everything else when it comes to your loved one. We maintain a safe reserve of ashes through the process, use QR codes for tracking at every stage, and work on every customer in isolation.

Does the amount of ashes determine the size of a Diamond?

Surprisingly, no. We can extract multiple grams of carbon from only 1/2 a cup of ashes or a healthy handful of hair, and we only need one gram of carbon to grow a Diamond.

Can I use ashes that have been sitting at home?

Absolutely! Ashes never expire. We have customers who send us ashes they have had for more than 20 years. The same is true with hair. If you have a lock of their hair at home, that also does not expire –– and we can use it to create a memorial Diamond.

Are Eterneva Diamonds genuine?

Absolutely! Eterneva Diamonds are genuine Diamonds. Diamonds are composed of carbon, and there is carbon in cremated remains. Like mined Diamonds, we also grade and certify Eterneva Diamonds to prove authenticity.

We guarantee that your Diamond will meet the minimum carat weight you ordered and be free of visible inclusions. A regrowth may sometimes be required if we don’t meet these standards, at which point we will grow you an additional Diamond to ensure we do.
