How Much Does a Cremation Diamond Cost? Prices, Process & Timeline

How much does a cremation diamond cost?

Quick answer: turning ashes into a diamond costs from about $995 to $999 for a small stone of roughly 0.10 to 0.19 carats, and most families choosing a stone under 0.5 carats pay $995 to $3,600 before any jewelry setting. Stones over one carat run about $6,000 to $25,000 or more, with some providers pricing their largest stones up to $75,000. The diamond itself is an addition to, not a replacement for, the cremation: our modeled national estimate for direct cremation is $3,030, and for cremation with a service it is $6,920, both modeled estimates in August 2026 dollars from NFDA 2023 medians adjusted for inflation, not quotes.

What a cremation diamond actually is

A cremation diamond, sometimes called a memorial diamond or an ashes-to-diamond, is a real lab-grown diamond made from carbon extracted from a loved one's cremated remains or hair. It is chemically and physically identical to a mined diamond. The difference is only where the carbon comes from. It is not a simulant, and it is not a stone with ashes mixed into it: the carbon itself is crystallized into diamond.

That distinction matters because cremation keepsakes come in two very different kinds. One kind holds ashes: lockets, pendants, and glass pieces that contain a small amount of remains. A cremation diamond is made from the remains, by converting their carbon. This guide covers diamonds only; the holding kind of keepsake is a different purchase, covered in our guide to urns and keepsakes.

What it costs, by size

Published prices from the main providers line up closely at the small end and spread out at the large end. Two factors drive nearly all of the price: carat size and color. Colorless stones cost the most at any size because they are hardest to grow without impurities; yellow stones are typically the least expensive, with blue, green, red, pink, and black in between depending on the provider.

Stone sizeTypical published price (diamond only)Notes
0.10 to 0.19 caratsFrom $995 to $999Smallest stones; yellow is usually the entry price
0.25 to 0.29 carats$1,200 to $2,200Colorless at the higher end of this band
0.50 to 0.69 carats$2,800 to $4,000A common choice for a ring or pendant
1.00 to 1.29 carats$5,700 to $9,000Classic setting often included at this size
Over 2 carats$25,000 to $75,000Provider range varies widely; longest timelines

Three costs sit outside the diamond price and are easy to miss. First, the setting: a pendant setting typically adds from about $520 and a ring setting from about $620 at the small end, though many providers include a classic setting once the stone reaches about 0.75 carats. Second, independent certification: IGI certification is often included for stones of one carat and up and a paid option below that, with GIA grading available on request. Third, shipping and insurance: most providers include insured shipping in the published price, but confirm it, since a lost package containing ashes is a different problem from a lost parcel.

How ashes become a diamond

The process has four stages, and understanding them explains both the price and the wait:

  1. Carbon extraction. The lab isolates carbon from the ashes or hair and purifies it. Cremated remains are mostly calcium phosphate, so only a fraction of the material is usable carbon, which is why providers ask for more ashes than the stone itself contains.
  2. Graphitization. The purified carbon is converted into graphite, the same soft material used in pencil lead.
  3. Growth (HPHT). The graphite goes into a high pressure, high temperature press that recreates the conditions deep in the earth. Over weeks to months, the carbon crystallizes into a rough diamond. This is the longest stage, and bigger, clearer stones take longer.
  4. Cutting, polishing, and grading. The rough stone is cut and polished like any diamond, then graded for carat, color, clarity, and cut, and certified.

Total published timelines run from about two months to about a year: some providers quote four to six months for a typical order, others seven to twelve months, with the largest sizes and select colors taking the most time. Ask for the timeline in writing before you send anything, and ask what happens if growth fails. Reputable providers keep reserve carbon so a failed growth can be retried without asking you for more ashes.

How much ash you need, and what happens to the rest

Most providers ask for about half a cup of ashes, roughly 100 to 200 grams, while some need only about 50 grams (around two tablespoons) for a small stone. Hair orders generally need about a cup of loosely packed hair. Either way, a typical cremation produces far more ashes than one diamond uses, so the remainder stays available for an urn, a columbarium niche, or scattering, covered in our scattering ashes guide.

Questions to ask before you order

One caution applies to every provider: a memorial diamond is a keepsake purchase, not an investment. Custom-grown stones do not hold their purchase price on resale, so choose the size for what it means to you, not for what it might be worth later. If the budget is the constraint, a smaller stone, or a simple keepsake that holds ashes, serves the same purpose for far less.

Frequently asked questions

How much does it cost to turn ashes into a diamond?

Published provider prices start at about $995 to $999 for a small stone of roughly 0.10 to 0.19 carats. Most families choose a stone under 0.5 carats, which typically runs $995 to $3,600 before any setting. A stone of 0.25 to 0.5 carats commonly costs $2,000 to $6,000, and stones over one carat range from about $6,000 to $25,000 or more, with some providers pricing their largest stones up to $75,000. Size and color drive almost all of the price difference.

Are cremation diamonds real diamonds?

Yes. A cremation diamond is a real, lab-grown diamond, chemically and physically identical to a mined diamond. The only difference is the source of the carbon: ashes or hair from your loved one instead of carbon mined from the earth. It is not cubic zirconia, moissanite, or any other simulant. Larger stones are usually graded by an independent lab such as IGI or GIA; smaller stones typically ship with the provider certificate only, so ask what certification is included at your size.

How long does it take to turn ashes into a diamond?

It depends on the provider and the size, and published timelines range from about two months to about a year. Some providers quote four to six months for a typical order, others seven to twelve months, with larger and colorless stones taking longest because growth is the slowest stage. If you need the stone by a specific date, such as an anniversary, confirm the timeline in writing before you send the ashes.

How much ash do you need to make a cremation diamond?

Most providers ask for about half a cup of ashes, roughly 100 to 200 grams, though some need only about 50 grams (around two tablespoons) for a small stone. A typical cremation produces far more ashes than that, so most of the ashes remain for an urn, a niche, or scattering. Hair can also work: providers generally ask for about a cup of loosely packed hair, and some will combine a small amount of hair with ashes if you are short on either.

Can you make a cremation diamond from hair instead of ashes?

Yes. Labs extract carbon from hair the same way they do from ashes, and providers generally charge the same price for a hair diamond as for an ash diamond. This matters when ashes were already scattered or buried, or when a family member wants a diamond made while the person is still living, from a lock of hair kept for that purpose.

Is a cremation diamond worth the cost?

That depends on what you are buying it for. As a keepsake, a diamond is permanent, wearable, and passable to the next generation, which is the point for most buyers. As an investment, it is not: memorial diamonds are custom-grown from a specific person carbon source, and resale value is far below the purchase price. If the budget is tight, a simple keepsake that holds a small amount of ashes costs far less and serves the same emotional purpose for many families.
