The two things are almost never in the same room. The urn sits somewhere deliberate, a shelf, a sideboard, a spot chosen carefully. The hair is in an envelope in a drawer, if any was cut at all. Ash and hair for a partner memorial diamond are measured against two separate figures: typically a few tablespoons up to roughly 4 oz of cremated remains, or a small lock of a few grams of hair.
Read the “or” in that sentence carefully, because it is the whole post. Submitting both does not add the two allowances together into something larger. A combined order is not a double order.
Memorial Diamond grows these stones, so treat this page as interested rather than neutral, and every number on it as an industry wide range rather than our published requirement. What follows is mostly about what a second source changes, less than people assume, and about the one genuinely new decision it creates.
Table of Contents
What a Second Source Actually Changes
Start with the shorter list, which is the list of things a second source does not do.
Sending both ash and hair for a partner memorial diamond does not make a bigger diamond. It does not shorten the wait. It does not raise the proportion of the finished stone that came from your partner. It does not halve either requirement, and it does not let a short quantity of one material be topped up by the other. People arrive at ash and hair for a partner memorial diamond expecting an additive answer and there isn’t one.
What it does change is real, though, and worth the trouble:
- Redundancy. If one half of the ash and hair for a partner memorial diamond you hold disappoints on assessment, the order does not necessarily end.
- Access. Authority over ash and hair for a partner memorial diamond rarely rests with one person. Sometimes the ashes are controlled by someone else and the hair is not, or the reverse.
- Meaning. Some people simply want both included, and that is a sufficient reason on its own without technical justification.
- Timing. The ash and hair for a partner memorial diamond can often be committed at different moments rather than together.
That last one is the decision this page exists for. Everything else about ash and hair for a partner memorial diamond is already settled by the two single material figures. Sequencing is the part nobody tells you about in advance.
How Much Ash and Hair for a Partner Memorial Diamond Does a Combined Order Take?
The ash and hair for a partner memorial diamond are assessed against separate bands, independently of one another.
For cremated remains, the industry typical requirement runs from a few tablespoons up to roughly 4 oz (about 100 g). For hair, it is typically a small lock, a few grams. The reason the two halves of ash and hair for a partner memorial diamond carry such different figures is carbon content: hair is roughly 50% carbon by weight, while cremated remains yield only about 0.5% to 4%, because ash is overwhelmingly calcium phosphate rather than carbon.

Any provider you approach will have its own numbers inside those bands, so the specific quantity of ash and hair for a partner memorial diamond you are asked for is a figure to get in writing from them, not something to infer from a page like this one. Ask three things about the ash and hair for a partner memorial diamond when you do:
- Is each figure a received weight or a usable weight? Processing removes whatever is not carbon, and two companies may answer it differently without either of them being wrong.
- Are the ash and hair for a partner memorial diamond assessed separately or as one submission? This determines whether a shortfall in one is fatal to the order.
- Does submitting ash and hair for a partner memorial diamond together change the required quantity of either? The honest expectation is no, but it is a policy question, not a chemical one.
Beyond those figures, the quantity of ash and hair for a partner memorial diamond stops mattering. Carat comes from time in an HPHT growth cell, which runs at 1,400 to 2,500°C under something like 6 to 8 GPa for weeks or months on end, as documented in the general literature on diamond growth methods. Stones run from about 0.10 ct to 5+ ct, and the industry typical timeline is 6 to 10 months, stretching toward 12 for larger or specialty color work. None of those numbers moves because you sent ash and hair for a partner memorial diamond instead of one material. The full sequence for a combined submission covers what happens once both have been accepted.
Does Using Both Make the Stone More of Your Partner?
No, and this deserves a direct answer rather than a tactful one, because it is the reason many people submit both in the first place.
The carbon recovered from ash and hair for a partner memorial diamond is a minority of the finished stone. Industry figures for the ash route put that personal fraction at something like 10 to 15% of the stone’s mass, some providers as low as 3%, and no published figure covers a blended charge of the two materials. Whatever is recovered gets purified to roughly 99.9%+, converted to graphite, and then topped up with lab grown carbon until there is enough feedstock to fill a growth cell. Sending ash and hair for a partner memorial diamond puts two personal inputs into that same recovered fraction. It does not enlarge the fraction.

There is a subtler version of the same hope: the idea that hair from life plus ash from after captures more of a person than either alone. That is a real feeling and nobody should argue anyone out of it. But it is a feeling about meaning, not a claim about material, and the two should not be confused when money is involved. A single source stone and one grown from ash and hair for a partner memorial diamond are, in every measurable respect, the same object.
What is true, and is plenty: a verifiable portion of your partner’s own carbon sits permanently inside the crystal lattice of a real diamond, graded against the same 4Cs as any other stone. Color, incidentally, is not something a second source lets you steer either. Nitrogen present during growth reads yellow, boron reads blue, and colorless requires the absence of both. What color a combined stone is likely to be covers why that remains a probability rather than a choice.
Which Material Gets Committed First?
Here is the decision that ash and hair for a partner memorial diamond forces on you and a single source order never does.
The two halves of ash and hair for a partner memorial diamond carry different risks. Ash is usually the larger, more contested, more irreversible thing to part with, and frequently it is not exclusively yours to send. Hair is small, often already in your possession, and rarely subject to anyone else’s permission. Sending ash and hair for a partner memorial diamond at once means committing the harder material before you know whether the process works for you.
| The decision in front of you | What to settle before anything is posted | Who actually answers it |
|---|---|---|
| Whether to send the ash and hair for a partner memorial diamond together or one at a time | Whether the provider accepts a staged submission, and whether a second material can be added after an order opens | The provider, in writing, before payment |
| Which material is more exposed | Whether the ashes are yours to divide at all, given the law of the state and anything your partner left in writing | A funeral director, and whoever holds legal authority over the remains |
| Whether a sample that may fall short is worth sending | Whether that material gets returned, kept, or quietly absorbed if it fails assessment | The provider’s written policy on unused material |
| Whether to hold hair back deliberately | Whether anyone else may want a stone later, since a second order needs its own material | You, and anyone else in the family who may ask |
| Whether the order is time sensitive | Whether a scattering, interment or family handover is already scheduled for the ashes | Whoever is organizing it |
| What “committed” actually means | At what point material stops being returnable, on receipt, on assessment, or at graphitization | The provider, and this is the single most useful question on this page |

The last row is the one to send as an email today. Once material is graphitized it is not coming back in any recognizable form, and knowing exactly where that line falls is what lets you decide the order in which to cross it. The questions worth asking before anything is arranged is the fuller list to work through.
What If One Source Turns Out to Be Short?
This is where ash and hair for a partner memorial diamond earns its keep, and the answer depends entirely on a policy question you can settle in advance.
If the ash and hair for a partner memorial diamond are assessed separately, a shortfall in one does not automatically end the order. The other can usually proceed on its own. If they are treated as a single pooled submission, a shortfall may stall everything. That difference is not chemistry and it is not standardized, so ask before you post anything.
Three common shortfalls and what typically happens next:
- Not enough ash, plenty of hair. The most survivable case. Hair carries roughly 50% carbon against ash’s 0.5 to 4%, so a few grams does the work of several ounces, and the order usually continues as a hair based one. The hair figure taken on its own sets out what that looks like.
- Plenty of ash, no usable hair. Equally workable, and common where a partner was cremated without anyone thinking to cut a lock. The ash figure on its own covers the requirement and why it is what it is.
- Both short. Rarer, and the one case where ash and hair for a partner memorial diamond is genuinely a stop rather than a detour. Ask whether a partial assessment is possible before committing, and ask what happens to material already sent.
Nothing about a shortfall is a judgment on what you kept. Plenty of people hold a keepsake urn given at a funeral, or a few strands from a brush, and were never told either might matter later. Getting ash and hair for a partner memorial diamond assessed early, before any plan is built on it, is the cheapest way to find out where you stand.
Two Materials, Two Sets of Rules
The final thing ash and hair for a partner memorial diamond introduces is that the two sit under different kinds of authority, and people are frequently surprised by which one causes trouble.
Cremated remains sit inside a chain of control that differs from state to state and can be overridden by anything your partner set down in writing. Where a relationship was legally recognized, that is usually straightforward. Where it was not, no marriage, no civil partnership, a family that never acknowledged the relationship, a spouse from an earlier marriage still named on the paperwork, the urn may be controlled by someone who is not you. That has to be established before money moves, not after.
The rules covering cremated remains are generally aimed at the remains themselves, so hair already sitting in your own home is usually a simpler question in practice. That is practice rather than settled law. A person’s personal effects can fall to their estate, and this varies by state, so three qualifications matter:
- If the hair is in someone else’s keepsake box, it is theirs to share or refuse, regardless of what the law says about remains.
- If a funeral home holds a cut lock, they will release it to whoever is on record as authorized, which may not be you.
- If personal effects were named in a will, a lock kept in a locket may fall under it.
So an order built on ash and hair for a partner memorial diamond can genuinely be easier or harder than a single material one depending on which is contested. Where the ashes are out of reach and the hair is not, the practical answer is often to proceed with hair alone rather than to fight for a portion you may not be entitled to. The complete guide to a partner ashes and hair diamond works through both routes in full.
Frequently Asked Questions
Does sending both materials produce a larger diamond?
No. Carat is set by growth time in the press, not by how much material arrives, so a combined submission and a single source one at the same carat take the same months and cost the same. Two sources buy redundancy and meaning, not size.
If the ashes fall short, does the hair make up the difference?
Only if the provider assesses the two separately rather than as one pooled submission. When they are assessed separately, a hair only order usually proceeds. Ask which model applies before you send anything, and get the answer in writing.
Which should I commit first if I only want to risk one?
Usually hair, because it is smaller, generally already in your possession, and rarely subject to anyone else’s permission. That lets you see how a provider actually handles your material before the ashes, the harder, more contested thing, are committed.
Does a dual source stone contain more of my partner than a single source one?
No. Industry figures for the ash route put the personal carbon near 10 to 15% of the finished stone’s mass, and no published figure covers a blended charge. Either way, a second input shares that fraction rather than enlarging it. Send both for meaning and redundancy, not proportion.
Can the two materials be grown into two separate diamonds instead?
Frequently yes, since each meets its own minimum independently, one stone from ashes, one from hair. That is a genuinely different order with its own cost and its own timeline, so ask for it to be quoted separately rather than assumed.
The hair is mine to give but the ashes are not. What then?
Then proceed with what is actually yours, and treat the ashes as a separate conversation with whoever holds authority. A hair only order is not a compromise version. It is the same process, the same stone, and the same grading.
Final Thoughts on Ash and Hair for a Partner Memorial Diamond
Most of the work here turns out to be subtraction. Two sources do not double the allowance, do not enlarge the personal fraction, do not speed anything up, and do not give you a bigger stone. Once all of that is cleared away, what remains is small enough to act on.
Six things are worth acting on, in this order:
- Get both figures for ash and hair for a partner memorial diamond in writing, stated separately.
- Ask whether each is a received or a usable weight, since the two are not the same number.
- Ask whether the materials are assessed separately or pooled, because that answer decides what a shortfall costs you.
- Find out where the point of no return sits, receipt, assessment, or graphitization.
- Settle who controls the ashes before money moves, and ask who holds any cut lock.
- Commit the easier material first, usually the hair, and the contested one second.
Handled in that order, ash and hair for a partner memorial diamond stops being a question about quantity and becomes what it actually is, a question about which thing you are willing to send while you still have the option of changing your mind.
