A memorial diamond is a lab-grown diamond created with carbon taken from cremation ashes or hair.

Orders usually involve a memorial-diamond company, an HPHT lab-growth process, and a jewelry workflow that looks a lot like buying any other diamond: pick carat target, pick cut and color, then decide whether you want a loose stone or a finished ring or pendant. Names you will see in this niche include Eterneva, Algordanza, LifeGem, and LONITÉ, plus third-party grading labs if you request outside certification.

Families who want to turn ashes into diamonds usually run into three pricing layers: the stone itself, any customization (cut, color, size), and anything that makes it wearable (a ring or pendant setting). Some companies publish price charts, while others move straight to consultation quotes, so the same 0.25-carat target can still land in different totals once you pick color, paperwork, and jewelry work.

One widely shared U.S. pricing page shows memorial-diamond pricing from $3,499 up to $75,000 based on size, shown in the diamond pricing chart as of March 2026.

A second provider lists a starting price of $2,999 for a 0.30-carat diamond and describes three quote levers: weight, whether the stone is cut or left rough, and the carbon source, on its starts at $2,999 page as of March 2026.

For another published ladder, one provider lists pricing from $1,400 for 0.25 ct to $28,500 for 3.0 ct, a spread of $27,100 because $28,500 minus $1,400 equals $27,100, on its U.S. cost table as of March 2026.

Memorial diamonds are priced per stone, and the unit changes with carat size and cut. A rough stone, a polished stone, and a finished ring can share the same origin material, yet land on different totals because the labor and paperwork differ.

What you’re actually buying

A memorial diamond is a lab-grown diamond that uses carbon isolated from cremation ashes or hair. The company collects the material, processes it to isolate carbon, and grows a diamond in a controlled environment before cutting and polishing the stone. Buyers can choose a loose stone or have the diamond set into jewelry, which changes the scope from a gemstone order into a jewelry order.

It is not the same as cremation jewelry that stores ashes inside a compartment. It also is not a standard lab diamond bought off a shelf, because part of the value proposition is chain-of-custody handling and the promise that the stone’s carbon is tied to the person or pet being memorialized.

What people pay in real orders

Case A A family orders a small, stone-only memorial diamond and plans to keep it in a safe or display case. This path avoids jewelry design choices, resizing, and repair work, but it can still include optional paperwork if the buyer wants outside certification or an appraisal for insurance.

Case B A buyer wants a pendant that is ready to wear, so the order includes a stone plus a setting. The diamond is only one line item. Metal choice, design complexity, and whether the setting is made by the memorial-diamond company or a local jeweler changes the timeline and the “who fixes it later” question. For other memorial formats that skip diamond production entirely, costs and logistics look different, which is clear when comparing options like reef memorials and tattoo preservation.

Case C A household orders more than one stone so multiple relatives can have a matching keepsake. That decision often turns into a second round of spending because each stone may need its own setting, its own paperwork, and its own insurance documentation. A third-party comparison notes that some companies also pitch bulk-order discounts and add-ons like laser engraving during the buying process on the company-by-company pricing overview dated October 7, 2022.

Price breakdown by line item

A memorial-diamond quote often looks simple on the surface because it is presented as a diamond of X carats, but the invoice is usually a bundle of steps. The carbon sourcing and purification step is the front end, then the growth phase (which is tied to the target size), followed by cutting and polishing. If you choose a finished ring or pendant, that adds jewelry labor and materials. Paperwork can sit in either bucket, depending on whether it is a lab report, an appraisal, or an internal certificate.

This is the part many buyers miss. Two vendors can both advertise a 0.30-carat memorial diamond, yet one price includes a polished stone and the other starts with a rough stone, or one includes jewelry work and the other assumes you will handle a setting later, which is why matching “what’s included” matters as much as carat size.

Line item	Usually included in the base stone	Often an add-on	Buyer decision
Carbon processing and growth	Yes	No	Choose ashes, hair, or both
Cutting and polishing	Sometimes	Sometimes	Rough vs finished stone
Color and cut style	Basic options	Custom options	Pick the look you want
Setting into jewelry	No	Yes	Stone-only vs ring or pendant
Documentation and valuation	Basic certificate	Appraisal or lab report	Needed for insurance

Hidden costs that show

Paperwork costs money.

Shipping policies can also affect the real total and the risk you are taking on. One FAQ lists a finished-diamond shipping charge of $49 and notes customs handling can vary by destination on its shipping cost answer.

Another common late bill is jewelry work after delivery. A stone-only purchase becomes a second project when you ask a local jeweler to set it, resize it, or repair prongs. If the diamond is already mounted, maintenance still exists, it just shifts into cleaning, inspections, and potential resizing if the ring fit changes.

Worked example for a basic order

This is a math exercise using published figures, not a promise of a final quote. It shows how multi-stone orders can change the total when a company publishes different per-stone pricing for quantity.

• A public list shows a 0.25 ct stone at $3,499 each, and $3,199 each when ordering two or more, on its U.S.-currency price grid.

Two stones at the single-stone price total $6,998 because $3,499 multiplied by 2 equals $6,998. Two stones at the “two or more” price total $6,398 because $3,199 multiplied by 2 equals $6,398. The difference is $600 because $6,998 minus $6,398 equals $600.

This kind of discount can matter in families where siblings want matching keepsakes. It can also be less relevant if each stone ends up needing a separate custom setting, separate paperwork, and separate insurance documentation.

What changes the quote the most

Carat size drives the biggest jumps because growth time and yield are tied to the target stone. Cut choice, color choice, and whether you want a loose stone or finished jewelry follow behind that, and then you get the extras bucket, including documentation and upgrades to settings or metal.

One provider’s own explainer describes premium selections as running from $9,000 to over $25,000 for larger and rarer choices, tied to size and color options, on its premium tier costs page dated March 19, 2026.

Where the money goes after delivery

After delivery, most spending falls into three buckets: setting work, documentation for insurance, and upkeep. A memorial diamond is still a diamond, so prongs can loosen, rings can need resizing, and settings can get scratched or bent. If the order is stone-only, the first post-delivery expense is usually having a jeweler set the stone, then deciding whether to pay for an appraisal and an insurance rider.

If you want a comparison point for how memorial spending can shift from product to service, it helps to look at other end-of-life purchases that are more standardized. Casket pricing, for instance, is a tangible product with different tradeoffs and fewer custom steps than a memorial diamond, as shown in casket cost examples.

None of this makes a memorial diamond a bad choice. It just means the total can include follow-on work even after the stone is delivered, especially if you change your mind about jewelry style later.

Who this cost makes sense for

Makes sense if

• You want a wearable memorial that is more than a container for ashes.
• You are comfortable paying for a custom process tied to carat size and finish level.
• You can wait through production time and want a defined chain-of-custody workflow.
• Your budget has room for a setting, documentation, and future maintenance.

Doesn’t make sense if

• You want the lowest-cost diamond and do not care about carbon source.
• You prefer a keepsake that holds ashes directly.
• You need the memorial quickly and cannot wait through production time.
• You want a purchase that behaves like standard jewelry resale.

A memorial diamond is a premium choice because it is part gemstone, part memorial service. People who want a simple keepsake often land on a different type of memorial product, while buyers who want a long-term wearable memento often accept the higher price ladder.

Answers to Common Questions

How much ashes do you need to make a diamond?

Requirements vary by company, and some accept hair, ashes, or a combination. Providers often describe minimum material needs during intake and consultation.

Is the memorial diamond a real diamond?

Memorial diamonds are lab-grown diamonds. The differentiator is that the carbon source is tied to ashes or hair, not that the material is an imitation.

Can you turn pet ashes into a diamond?

Yes, some companies market memorial diamonds for pets as well as humans, with pricing tied to the same size and finish choices.

Do you have to buy a ring or pendant?

No. Many buyers order a loose stone and decide later whether to set it into jewelry.
