What Is a Memorial Diamond?

A memorial diamond — also known as a cremation diamond, or “ashes to diamonds” — is a genuine lab-grown diamond created using carbon extracted from cremated ashes or a lock of hair. Turning ashes into a diamond takes a few months, and every stone is grown individually from your loved one’s own carbon, so no two are ever alike.

It is chemically, physically, and optically identical to a mined diamond. The difference is its origin — created from memory, not the earth.

Why Families Choose Memorial Diamonds

There isn’t one “right” reason families choose memorial diamonds. Here are a few gentle truths families often share.

Intimacy

To feel close again

— in quiet moments, when words don’t help.
Presence

To keep their love with you

in a form you can carry every day.
Show more Show less
Remembrance

To hold a memory

in something real, not only a memory.
Heritage

To create a legacy

a memorial diamond that can stay in the family.
Reflection

Is a Memorial Diamond
right for You?

This choice is personal. And it’s okay if the answer is “not right now” — or “not for me.”

Not for everyone

Some families prefer a different kind of memorial — and that is completely valid.

How Memorial Diamonds Differ
from Keepsake Jewelry

Keepsake Jewelry
Memorial Diamond

Container-Style

Holds ashes or hair inside a small chamber.

Transformation

Created from purified carbon extracted from ashes or hair.

Symbolic

The memory is carried in the jewelry, but remains separate from the material.

Real Diamond

A genuine wearable diamond, just like any other diamond.

Both are meaningful — families choose based on what feels right.

How memorial diamonds are made

A memorial diamond is grown, not assembled. The full walkthrough lives on our ashes-to-diamonds process page; in short, it happens in six stages.

Carbon extraction. The ashes, hair or fur arrive and the carbon is separated from the other elements present. Cremated remains are mostly not carbon — calcium and phosphorus dominate — so this stage is about isolating the small fraction that can become a diamond.

Purification. The extracted carbon is refined until what remains is graphite of the purity a diamond needs. Impurities left at this stage show up later as flaws in the crystal, so it is not rushed.

Growth. The graphite goes into an HPHT press — High Pressure, High Temperature — together with a small diamond seed. Over the following months, carbon atoms attach to that seed one layer at a time and a single crystal forms. This is the stage people find hardest to wait through, and it cannot be shortened: the crystal grows at the speed the physics allows, and a diamond hurried is a diamond with flaws in it.

Cutting and polishing. The rough crystal is cut by hand. Round brilliant, princess, emerald, cushion, radiant, asscher, pear — the cut is your choice, and it changes how the stone carries light more than any other decision you will make.

Engraving. Initials, a date or a short phrase, laser-inscribed on the girdle where it is invisible to the eye and readable under magnification. Optional.

Certification. Every diamond leaves with a Saint Diamonds certificate recording its authenticity and origin.

What we need from you

Ashes: about half a cup, roughly 100g. That is a small fraction of what a cremation produces — most families are surprised by how little we ask for, and it means you are not choosing between a diamond and keeping remains to scatter or inter.

Hair: a lock is enough, and hair works just as well as ashes. That matters more than it might sound. It means a memorial diamond is possible when there were no cremated remains — a burial, a scattering that has already happened, or remains held by another family member. It also means a diamond can be grown from someone who is still alive, which people ask about more often than you would think.

Fur: accepted, and the process is identical. If you are here for a dog, cat or horse, our pet memorial diamonds page covers what is different about the arrangements.

How much does a memorial diamond cost?

Price is driven by three things: carat weight, colour, and the cut you choose. Larger stones take longer to grow and cost disproportionately more, which is why the difference between a half-carat and a three-carat is much greater than six times.

Our full pricing table sets out every carat weight and colour we offer, with no enquiry required to see it: see memorial diamond prices.

How long does it take?

Four to six months, from the day your sample reaches us to the day the finished diamond is delivered.

Most of that is growth. Extraction and purification take a matter of weeks; cutting, polishing and any engraving take a few more. The rest is the crystal forming, atom by atom, and there is no way to speed it up without compromising it — a shorter timeline would mean a worse stone, not a faster one.

We would rather tell you four to six months and be accurate than promise eight weeks and disappoint you at a time when you can least absorb it. If a particular date matters to you — an anniversary, a birthday, a scattering — tell us when you order and we will say honestly whether it is achievable.

Colours, cuts and carat weights

Memorial diamonds can be grown colourless, or in blue, yellow, green, red, pink or black. The colour comes from trace elements present during growth. It is a genuine property of the crystal rather than a coating or a treatment applied afterwards, so it will not fade or wear off.

Cut is a separate choice. Round brilliant returns the most light and is the most common. Princess and emerald read as more modern and more architectural. Cushion is softer. Pear and marquise are the most distinctive, and the ones people most often choose when the stone is going into a pendant rather than a ring.

See colours, cuts and carat weights.

Memorial diamonds for pets

The process is the same for a pet as for a person: ashes or fur, the same carbon extraction, the same growth, the same certificate. What differs is the practical side — how much is available, and what your crematorium can return to you. Pet memorial diamonds.

Setting your diamond into jewellery

A memorial diamond can be worn or kept loose. Loose stones are more common than people expect — some families want the diamond itself, in a box, and decide about settings years later. If you do want it set, the choice is a ring, a pendant or earrings, and it can be done at the time of order or at any point afterwards.

Certification: what comes with your diamond

Every memorial diamond is issued with a Saint Diamonds certificate confirming its authenticity and its origin — that this specific stone was grown from the sample you sent.

Independent grading by IGI or GIA is available as an optional addition. That gives you a third-party laboratory report on colour, clarity, cut and carat, issued by a body with no relationship to us. We would rather be plain about that split than let you discover it at checkout: if independent grading matters to you, ask for it up front and we will quote it.

Frequently asked questions

Are memorial diamonds real diamonds?

Yes. Same carbon crystal structure, same hardness, same optical properties as a mined diamond. The difference is the source of the carbon, not the nature of the stone.

How much ash is needed to make a diamond?

About half a cup — roughly 100g. That is a small fraction of what a cremation produces.

Can you make a diamond from hair instead of ashes?

Yes. A lock of hair is enough, and the finished diamond is identical. It is also how a diamond can be made when there are no cremated remains at all.

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

Four to six months, from receipt of the sample to delivery of the finished diamond.

Are cremation diamonds valuable?

Their value is personal rather than financial. Like almost all jewellery, a memorial diamond will not resell for what it cost, and it is not an investment. What it is, is a way of keeping someone with you that does not degrade, fade or need replacing.

What colours can a memorial diamond be?

Colourless, blue, yellow, green, red, pink or black. The colour is intrinsic to the crystal, not applied to it, so it will not fade.

Can I make a diamond from my pet’s ashes?

Yes — from ashes or from fur. See pet memorial diamonds.

Is the diamond certified?

Every diamond comes with a Saint Diamonds certificate of authenticity and origin. Independent IGI or GIA grading is available as an optional add-on.
