Stage one success! Your loved one’s ashes have been successfully purified into beautiful, sparkly carbon. Check out the process ahead. 🎥


1.5-2 months
A remarkable transformation

We isolate the carbon from ashes, which is the starting material for their diamond!

I have amazing news…your loved one is officially a raw diamond! Here’s a video from the growth – they did wonderfully. 🙌


2-3 months
A diamond emerges

Through a custom, individualized process of heat and pressure, your loved one’s raw diamond will grow.

Hey there. They just finished at the cutters. Gosh, they turned out stunning. 😍

Pet ashes to diamond, also known as cremation diamonds or memorial diamonds, are lab grown diamond created from the cremated remains of fur of your pet.

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 pet, their diet, and other factors.

All pet ashes can be turned into a diamond. We’ve had tons of cats and dogs, but also horses and even pet cockatoos! Anything that is alive is made of carbon because carbon is a basic building block element of life –– including your pets.

Absolutely! Eterneva diamonds are real 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 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!

It costs at least $2,999 to turn your pet’s ashes into a diamond. The final cost will depend on the carat size and color that you want.
You can find Eterneva reviews just about anywhere! Eterneva reviews are on Facebook and Google, TrustPilot, The Cremation Institute, or a collection here on our own site. You can even look at Instagram comments, stories, and pictures we’ve been tagged in to see customers who are sharing the legacy of their pet for everyone!

Eterneva’s goal is to memorialize the remarkable, and so many of our pets fit the bill. Their loss is no different than the loss of a human loved one. Our pets are our family, and they are right beside us through so many major life moments, like graduation, marriage, and even grief itself.

Our pets change who we are, and Eterneva works to tell the world about these amazing family members. We send monthly updates of every single step in the process. You can even come down to our Austin, TX lab and put your pet’s purified carbon in the diamond growth machine yourself.

Yes, at the end of the process you get a memorial diamond, but the grief journey throughout the 7-10 months it takes to transform your pet’s ashes into a diamond is often just as helpful. This is about who you become in the next chapter of your life, and how you bring your pet’s memories and how they made you a better person with you.

class=”paragraph-5″>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 an
  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.

Yes, you can use fur instead of cremated ashes to grow a diamond. Some customers have had memorial diamonds made for their pets while they are still here with us.

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 1-4% carbon in cremated remains. Only about 1 gram of carbon is needed to grow a diamond, with a 1/2 cup of ashes that will give us more than enough carbon to grow a cremation 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 not 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.
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 pet 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 pet’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!
