Frequently asked questions

Cremation diamonds are real diamonds made from the carbon left in cremated remains, or from the carbon in someone’s hair. Cremation diamonds are known by a few names including memorial diamonds and eternal diamonds.

They are grown using a lab grown application process within a high pressure, high temperature (HPHT) machine, first purifying the cremated remains (ashes) to extract the carbon left within. Cremated remains contain 1-4% carbon depending on the age of the person, their diet, and other factors.

The cost for turning ashes into diamonds varies based on the carat size and diamond color you want. Cost begins at $2,999 for a .1 carat blue, yellow or colorless diamond.

Cost goes up based on the amount of time the diamond is in the machine since we can only grow one diamond at a time. Larger carat sizes must be in the machine longer, and colors outside of yellow, blue or colorless must go through an additional coloration process. Larger diamonds are also most difficult grow so the pricing reflects the complexity of hand-crafting a large diamond. These factors are what makes the price increase.

Customers choose Eterneva because of the unique grief journey we provide. We film every step in the process to your loved one transforming into a diamond and send you monthly updates. We also inaugurate each one of our loved ones on social media (with permission) to make sure that our entire team and, eventually, the world knows about this remarkable life.

We do everything we can to fight against the second death (when someone’s name is said for the last time), and help our customers do tribute videos, plan homecoming parties for the diamond, launch legacy projects and so much more. We're a team of people that deeply cares and is personally connected to our work. This is less of a job and more of a calling for all of us.

Our grief journeys are unique, but that doesn’t have to mean they are lonely. We are here to work with you, to learn more about your loved one and what made them so special, and ultimately to celebrate the remarkable lives that make us who we are.

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

The ashes to diamond process includes multiple steps over the course of 7-10 months.

  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. The purification process takes about 6 weeks, and 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 your loved one’s carbon, generic 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 over the course of 2-6 weeks, depending on the carat size required.
  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 and ensure the diamond size we're targeting will fit nicely without any visible imperfections.
  5. The rough diamond will be cut by hand by master diamond cutters (no lasers here!) and colored to the specification of the customer. This can take up to 12 weeks depending on the cut and color of the diamond.
  6. The diamond will be sent to IGI for grading. The International Gemological Institute 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. We will plan a homecoming for your diamond, and have a team member or a courier hand deliver the diamond home to you. Some folks like to throw parties, or small gatherings. Others like to embrace this moment with their loved one. If desired, before the homecoming, we can help set the diamond. Otherwise, you can work with a local jeweler of your choice to have the diamond set in jewelry.

Absolutely. Both pets and people contain carbon, and can be turned into a diamond as a memorialization option. Read more information about memorial diamonds for pets.

Yes, cremation diamonds are real diamonds. Like a regular diamond, we grade and certify our diamonds to prove authenticity.

We guarantee your diamond will meet the minimum carat weight you ordered and be free of visible inclusions. If we don't meet these standards, we'll grow you an additional diamond to ensure we do!

You need much more than pressure alone to turn coal into a diamond. You’ll need pressure and heat! Roughly 870,000 pound-force per square inch (psi) at 2,500 degree Fahrenheit.

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. As an additional step for any customer who wants it, we will send their loved one’s ashes to TDI Brooks’s analytical chemistry lab for testing to determine the carbon contents at no additional cost.

It takes only 2-6 weeks for a cremation diamond, also known as a memorial diamond, to grow. However, the growing stage of the diamond is only one of seven steps to a finished memorial diamond. In total, the entire process takes 7-10 months depending on the carat size, cut and color desired.

Yep, you can use cremated ashes or hair to grow a memorial diamond.

The entire cremation ashes to diamond process takes approximately 7-10 months from start to finish.

Absolutely! We work with jewelers to help you find the perfect setting for your diamond if you’d like our help.

Some folks like to have a brand new piece of jewelry, and others like to put the diamond in a piece of jewelry they already own. Whichever option you prefer, we’re here to help you get the diamond in its setting so you can begin bringing your loved one with you in the next chapter.

We only need a half cup of ashes or hair to grow a diamond. If you have less, don't worry - a small amount goes a long way. Contact us for more information if you're unsure.

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.

We always extract extra carbon from ashes and store it securely onsite with your permission, so if ever you want to have additional diamonds made or lose your diamond, we can grow you another one. We encourage you to add your loved one’s diamond to your homeowner’s insurance policy so that insurance will pay for the full replacement cost.

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!

Yes, there is lots 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.
