Memorial Diamonds from Pet Ashes: Cost and What to Ask

A pet memorial diamond is a lab-grown diamond made with carbon taken from your pet's ashes or fur. Published prices from three providers in September 2026 started at about $1,400 to $3,499 and went up with size, and one provider says production takes 9 to 12 months. What you must send, what it costs and what you receive differ by company, so compare a few before you commit.

How is a diamond made from pet ashes?

Providers describe similar steps. They take carbon from your pet's ashes or fur, purify it, and grow a diamond under heat and pressure. The rough stone is then cut, polished and certified. Heart In Diamond says it uses HPHT, which means high pressure, high temperature.

Cremated remains are mostly calcium phosphates, according to the Cremation Association of North America, so only a small fraction is carbon. Eterneva says remains contain 1 to 4 percent carbon. That is why providers ask for a specific amount, or accept fur or hair. Ask any provider how it shows the carbon came from your pet, and what it does if there is not enough. LONITE says it will work with you, for example by adding hair, and it says it traces origin with analysis and gives an origin certificate that independent institutes can validate.

Is it a real diamond?

It is a lab-grown diamond. The FTC's Jewelry Guides say lab-created diamonds can have essentially the same optical, physical and chemical properties as mined diamonds, and call for clear disclosure, such as "laboratory-grown" or "laboratory-created". Look for that wording in any listing. Ask for an independent report. Eterneva says its diamonds get GIA grading reports, and LONITE says independent institutes can validate its origin analysis.

How much does a pet memorial diamond cost?

Prices depend on size, color and cut. These are the starting points the providers published in September 2026. They do not include everything, such as a ring or pendant.

Color changes the price. LONITE says amber takes the least processing and colorless the most. Heart In Diamond charges extra for some cuts, such as 10 percent more for emerald and 20 percent for oval. Ask what the quote covers: certification, shipping both ways, return of unused ashes and the setting.

How much ash or fur do you need?

Providers ask for different amounts:

• Eterneva: about half a cup of ashes, or about one cup of fur or hair.
• LONITE: at least 150 grams of ashes, or 5 grams of fur, feathers or hair, with the same amounts for pets as for people.

Eterneva says the amount you send does not change the size of the diamond, because the size is chosen. LONITE says size and color affect timing and price. A small pet may leave less than a provider asks for, and in that case fur or hair may be used. Ask what happens to unused ashes. LONITE says leftover ashes are incinerated separately, and that you can ask for remaining carbon to be returned.

How long does it take?

Plan on many months. LONITE says 9 to 12 months, depending on size and color, and Eterneva says growing time depends on the size and color you choose. Ask for a dated estimate in writing. There is no deadline to begin: Eterneva says ashes and fur do not expire, so you can wait months or years before deciding.

How do you send the ashes?

Most providers send a kit or shipping instructions. If you mail ashes yourself in the US, the Postal Service allows cremated remains only by Priority Mail Express, in a sealed, sift-proof container packed in its cremated remains box. International mailing has more rules. Follow the provider's instructions and use tracking. Keep back some ashes if you want to keep them elsewhere.

What should you ask before you pay?

• What is the total price, and what does it include?
• How much ash or fur do you need, and what happens to the rest?
• How do you track my pet's remains, and do you add carbon from another source?
• What report will I receive, and from which laboratory?
• How long will it take, and what is your refund policy if I change my mind?
• Can I pay in installments, and what are the terms? Eterneva lists financing through Affirm.

What are the alternatives?

If the cost or process does not suit you, a pinch of ashes can go into cremation jewelry, which typically costs less. You can also keep the ashes in an urn, plant a tree, or choose a garden stone.

What to do next

1. Ask the crematory how much ash you will receive, and keep it safe.
2. Request quotes and instructions from two or three providers.
3. Choose fur or ashes, and decide whether to keep some back.
4. Take your time. A diamond can be made months or years later.
