The lock you kept is probably not the color it was when you were small. That is usually where this question starts. The answer is that the color diamond his hair becomes is decided in the growth cell, not by the hair: a diamond made from your father’s hair will most often be yellow, champagne or blue, colorless is possible at a higher cost, and gray, white, black or thinning hair changes none of that.
Which means color is the one thing the lock cannot decide for you. You decide which color diamond to grow, on the order form, before anything is grown.

Does Your Father’s Hair Color Change the Color Diamond You Get?
No. White hair does not make a white diamond, black hair does not make a dark one, and a beard sample behaves exactly like a sample from his head.
Hair color is melanin, a pigment. Before any growth begins, the hair is heated in an oxygen free process that strips away everything that is not carbon, and the purified carbon is then converted to graphite at roughly 2,500 to 2,700°C. No pigment molecule survives that, which is why hair color never reaches the color diamond. What reaches the press is elemental carbon, and elemental carbon from white hair is indistinguishable from elemental carbon from anyone else’s.
Hair is roughly 50% carbon by weight, which is why a small lock is enough and why no cremation is involved. How a memorial diamond is made from your father’s hair walks through each stage.
What Actually Sets the Color of a Hair Diamond?
Trace elements present while the crystal grows. Boron in the growth cell produces blue. Nitrogen produces yellow. A colorless stone requires the near total absence of both, which is easy for a manufactured feedstock and harder for a personal, organic one.
His purified carbon is blended with supplemental lab sourced carbon to reach a workable volume, so the finished stone is not entirely one person, but the trace elements riding along with the personal carbon still steer the color of the whole crystal. That is why a color diamond in the yellow to blue range is the natural outcome of a hair source, and why colorless takes additional processing and additional cost.
The growth itself uses either an HPHT press or CVD deposition. Both lab growth methods are described here. The process takes weeks to months depending on the carat you order.
Which Color Diamond Can a Father’s Hair Become?
Industry typical outcomes, not a promise about any one stone. The five rows below are the honest color diamond menu for a hair source.
| Color | Where it comes from | What it means for you | Cost position (industry typical) |
|---|---|---|---|
| Yellow | Nitrogen present during growth | The most common natural outcome of a hair source | Bottom of the band at a given carat |
| Champagne / brown | Several trace elements acting together | Reads as a warm neutral; not caused by brown hair | Level with yellow at matching carat |
| Blue | Boron present during growth | A target the lab steers toward, not something the lock supplies | Banded with yellow and champagne, under colorless |
| Colorless / white | Near total absence of boron and nitrogen | Achievable; requires extra processing | The clear step up at the same carat |
| Red, pink, green, black | Post growth irradiation, after the crystal exists | Unrelated to the hair; availability varies by provider | Quoted as an add on; black or 2 ct+ can push toward 12 months |
Once the stone is finished, a color diamond is graded on the same scale as any other diamond. How gemologists grade a diamond’s color, cut and clarity applies to a memorial stone too. The broader memorial diamond colors for a father post covers how each tone reads in different metals.
Does a Small or Old Hair Sample Limit the Color Diamond You Can Order?
No. A few grams, a palm sized lock, or what a barber swept up, is the industry typical amount, and the amount has no bearing on color. Neither does age: a lock his own mother kept from his first haircut and a sample cut last month yield the same carbon and the same color diamond options. How much hair you need for a father memorial diamond covers the quantity side.
Three things do matter, so write them down before you send anything:
- The color you want. Name it explicitly on the order: yellow, champagne, blue or colorless, rather than leaving it to a default.
- The carat. Growth time, not hair quantity, sets size, and size moves cost far more than color does.
- Whether you want a grading report. Independent grading is the only way to confirm the finished color against what you ordered.
If you are choosing between sending hair, ashes, or both, a color diamond from your father’s ashes lands in the same range, and sending both does not widen it.
If Several of You Want a Stone, Will They Match?
Not automatically. Because so little hair is needed, one lock can often supply more than one diamond, but each is grown in its own run, and no two runs are identical.
If matching matters to you and your siblings, order the same color diamond explicitly on every stone, expect small shade differences within that color, and ask for independent grading so each stone’s color is documented. A slight difference is normal; it is not a sign that one stone got more of him. Whether more than one family member can have a diamond from the same father covers the sharing question in full.
Frequently Asked Questions
Will a Diamond From My Father’s Gray Hair Be Gray?
No. Gray and white hair have lost their pigment, and pigment is destroyed long before growth anyway. A color diamond made from gray hair comes out in the same yellow, champagne, blue or colorless range as one made from any other hair.
Can I Get a Colorless Diamond From His Hair?
Yes. Colorless requires excluding the boron and nitrogen that give hair diamonds their natural tint, which means extra processing and a higher price at the same carat. It is a choice you specify when ordering, not something the hair decides.
Does Dyed or Treated Hair Affect the Color?
Not the diamond’s color. Dye is pigment, and pigment does not survive purification. Whether a provider accepts chemically treated hair is a separate policy question, so ask before sending a sample.
Is Beard Hair Different From Head Hair for a Color Diamond?
No. Both are keratin at roughly 50% carbon, both are purified to elemental carbon, and both produce the same range of colors. If beard hair is what you have, it works.
Which Color Diamond Is the Most Common From Hair?
Yellow and champagne tones, because nitrogen and combined trace elements are the usual companions of organic carbon. Blue is steered toward deliberately, and colorless is the exception that costs more.
Can the Color Be Changed After the Diamond Is Grown?
Only by post growth irradiation, which some providers offer to turn a color diamond red, pink, green or black. It is quoted as an add on and cannot turn a tinted stone colorless. Colorless has to be grown that way.
Does the Color Say Anything About Who My Father Was?
No. Nothing molecular survives graphitization, so the color carries no information about him. Choose it as a color you want to look at, not as a message from the stone.
Final Thoughts on the Color of a Father’s Hair Diamond
The lock you kept will not tell you what color diamond it becomes, and that turns out to be a kindness. It hands the decision back to you. Whether his hair was dark or white, thick or almost gone, the carbon is the same, the color diamond menu is the same, and the choice is yours to make deliberately rather than something to wait for.
