General questions

Once you place an order, we’ll send you a cell isolation kit with easy-to-follow instructions. You collect 30 or more hairs with roots and send them back to us in the pre-labeled envelope. Our team then isolates and preserves the cells and places them within crystal-clear, skin-safe resin to create your Cellstone. Once completed, your Cellstones will arrive carefully packaged and ready for your jeweler to set in the jewelry piece of your choice.

We provide multiple Cellstones as back-ups in case resizing or adjustments are needed. If resizing affects the original setting, your jeweler can use one of these additional Cellstones.

The additional Cellstones included in your order serve as replacements in case of damage, ensuring you can continue wearing your jewelry without worry.

For the Ultimate Cellstone package you can choose between Crystal, Yellow, Orange, Pink, Red, Blue, Aqua, Turquoise, Light Turquoise, Lime, Violet, Lilac, Caramel, Brown, Gray, and Black.

For the Premium Cellstone package you can choose between Crystal, Blue, Yellow, Purple, Red, Lime, and Pink. Ultimate package color can also be chosen as an add-on.

For the Standard Cellstone package there is only crystal.

Cellstones can be set into most types of jewelry, such as rings, pendants, bracelets, earrings, and more. In general, any jewelry piece with at least space for a 1 to 2-mm deep, 1 to 2-mm diameter indentation or hole can be fitted with a cylinder-shaped Cellstone.

Currently, we offer our services only to Germany. We plan to expand to the rest of Europe and the United States in the near future.

We are still evaluating average shipping and processing times, as these depend on various factors such as location, the quality and quantity of sampled hair, and the donor’s age and lifestyle, which can influence the time required to obtain cells for the Cellstones.

Processing and shipping include multiple steps: 1) delivering the isolation kit to the customer, 2) receiving the samples back, 3) processing the samples in our laboratory, and 4) shipping the final Cellstones to the customer. Hence, shipping takes the most time.

Using conservative estimates, standard processing may take 4–6 weeks for Germany.

Expedited options are available at an additional cost to shorten these times to 2-3 weeks for all locations and can be selected during checkout.

We offer expedited processing options such as express shipping and priority handling for an additional cost. This usually reduces delivery from 4–6 weeks to 2–3 weeks.

Another way to speed up the process is to provide more hairs (up to 80 per tube).

We offer numbing cream that can be added during ordering. This cream is usually used for waxing and tattooing to avoid pain.

Please note that even without the cream, the discomfort is very minimal and often exaggerated in Hollywood depictions.

When very painful without numbing cream, we suggest taking a warm shower first to help loosen the hair follicles. Most customers find the process tolerable with this preparation.

While the cells are embedded in the Cellstone, they remain invisible to the naked eye due to their microscopic size. With a professional optical microscope (≥ 100× magnification), you can view the cells within the material. However, the cylinder’s curvature prevents a clear image.

If any pre-cured, cell-containing material is left after making the Cellstones, we include it as a small, flattened drop, which could be viewed under a microscope. Otherwise, we always provide high-resolution microscopic images taken just before the cells are embedded in the stones. Either way, you can appreciate your Cellstone as a whole and know it contains a complete representation of your being with the eternalized cells.

Our process is carefully controlled, personalized, and monitored through the following steps:

(1) A unique identifier code follows your samples from the isolation kit to our laboratory and through the production of the Cellstones, ensuring your Cellstones contain your cells.

(2) We use new materials at every step, from handling your samples to producing your Cellstones. This prevents contamination and ensures you receive the highest quality.

(3) Photos of your cells are taken and included digitally with your delivery.

Cellstones are personalized gemstones created from your own cells, making each piece deeply personal and truly one-of-a-kind. Unlike traditional gemstones, Cellstones carry a part of your essence, creating a meaningful and lasting connection.

While a Cellstone resembles a gemstone and is crafted with similar care, it is different because it contains your cells and is made with a skin-safe epoxy resin, making it an artificial gemstone. This adds a personal and emotional significance that traditional gemstones don’t offer.

Yes, we offer flexibility in choosing shapes, and you can order a mix if you’d like different styles for different jewelry pieces by choosing our ultimate Cellstone package. We also recommend discussing your options with your goldsmith or jeweler for guidance.

You can find more information on our Cellstone Specification page.

Yes, you can order a Cellstone using your own cells or those of a loved one (please ensure you have their permission), making it a deeply meaningful and unique gift for special occasions.

You can choose any professional goldsmith or jeweler with experience in setting stones or modifying jewelry pieces in your preferred area. We include instructions for the goldsmith/jeweler to ensure a straightforward and secure process. If there are unique aspects of your ring, the goldsmith/jeweler can adjust to that.

Since each Cellstone is custom-made, please refer to our cancellation and refund policy for details. In a nutshell, once we receive your samples and have begun the process, we cannot offer a refund anymore and will deliver the final product. If you cancel before that point, we will deduct any incurred costs from your refund.

We highly recommend completing your order, as the Cellstones can be used for another piece of jewelry or at a later date.

Treat your Cellstone jewelry as you would any fine jewelry. Avoid harsh chemicals and clean it gently with a soft cloth or a jewelry cleaner safe for resin-based stones. Use a soft cloth instead of rough brushes to prevent scratches.

Our cell isolation and preservation process is highly reliable, but with certain cases, it may not be successful. This can occur if the quality of pulled hairs is not sufficient, if there is an issue during shipment, or if contamination occurs due to insufficient disinfection of the collection area. If this happens, we will contact you to discuss options.

Order & pricing questions

Currently, we offer our services only to Germany. We plan to expand to the rest of Europe and the United States in the near future.

Using conservative estimates, standard processing may take 4–6 weeks for Germany from ordering to receiving the final product.

Expedited options are available at an additional cost to shorten these times to 2-3 weeks and can be selected during checkout.

Each tier—Ultimate, Premium, and Standard—offers a unique combination of Cellstones, colors, sizes, and features. For details, pleae check our comparison table.

We include multiple identical Cellstones to serve as backups, ensuring your ring or other jewelry piece remains special for as long as possible. If your Cellstone is damaged or lost, your jeweler or goldsmith can quickly replace it with one of the backups.

Proposal rings also often require resizing after the proposal, a process that can damage the Cellstone. With the included backups, you can propose with the fully completed ring—including the Cellstone containing your cells—and then have it resized effortlessly, using a backup Cellstone when needed.

This approach reflects our commitment to customer satisfaction and ensures your personalized jewelry can last a lifetime.

Mixing colors and sizes is available only with the Ultimate tier. You can choose up to 20 stones and divide them into as many as 4 sets, each with its own quantity, size, and color. You can also decide for each set whether to include only your cells, only your partner’s, or a blend of both.

For example, you might order:

•10 cylindrical Cellstones at 1 mm in diameter, pink, using your partner’s cells

•5 cylindrical Cellstones at 2 mm in diameter, turquoise, using only your cells

•5 cylindrical Cellstones at 3 mm in diameter, with a 50/50 cell blend

Or simply select 20 identical Cellstones—same size, color, and cell source—to use as extra backups or in other jewelry pieces. Once you choose the Ultimate tier, you’re free to configure your perfect combination.

The Premium and Standard tiers are great when you only need one size and one color per order. The difference between the two are the Cellstone quantity, color, and mixing options.

• The Standard Tier is limited to Crystal.

• The Premium Tier includes 6 vibrant color options: Crystal, Blue, Yellow, Purple, Red, Lime, Pink. For an additional cost, you can also select Ultimate Tier colors.

• The Ultimate Tier offers the full range of 16 vibrant colors: Crystal, Pink, Aqua, Brown, Yellow, Violet, Turquoise, Caramel, Orange, Purple, Pale Teal, Gray, Red, Blue, Lime, Black.

Yes, you can upgrade your tier if the Cellstones have not yet been created. Note that if you decide to upgrade to Ultimate tier, we do require sending another isolation kit as two collection tubes are necessary for that tier, which will increase the processing time.

Downgrading is only possible before we receive your samples, as additional steps are involved at higher tiers.

Please contact us as soon as possible to make any changes. For more information, refer to our cancellation and refund policy.

Yes, for the entire Cellstone set (considered as the product), there is a 2-year warranty included against defects in material or workmanship. This means that if all your backup Cellstones are used within 2 years due to failures of the previous ones, you can claim a warranty.

We aim for our customers to enjoy their personalized rings for a lifetime. For this reason, we include for all product tiers multiple back-ups.

Since we do not install the Cellstone into the ring or jewelry item, the jeweler or goldsmith assumes responsibility for the proper incorporation of the Cellstone.

For more details, please refer to our warranty policy.

The digital certificate is included with all tiers and provides details about the creation process along with general information. This includes the origin of the cells, microscopy images of the cell types encountered, and the number of cells contained in each Cellstone.

Process & Instruction questions

The kit includes detailed instructions, a collection tube with preservation liquid, tweezers, disinfectant (non-alcohol based), four gloves in two sizes (XL and M, suitable for S, M, L, and XXL hand sizes), a pre-paid return envelope for the tube, and optional numbing cream when purchased.

You need to collect at least 30 hairs with visible roots (white material on the ends). Discard any hairs without roots, as they cannot be used. Please watch our instruction video that shows facial hair epilation as example.

For men, facial hair and pubic hair are recommended, as these typically have strong roots (make sure the hairs are short: max. 1.5 cm/0.5 inch). Scalp hair is another option but usually requires trimming after pulling and carries a higher risk of contamination.

For women, leg hair and pubic hair are recommended, as these typically have strong roots, make sure the hairs are short (max. 1.5 cm/0.5 inch). Scalp hair is another option when others fail but usually requires trimming after pulling and carries a higher risk of contamination.

Try pulling hairs from different areas as suggested in the guide. Most people can collect hairs from their face, scalp, legs, or crotch area.

If you still cannot reach the minimum required 30 good hairs after trying other locations, you can send the tube with whatever number you were able to collect. However, please note that fewer hairs reduce the likelihood of a successful outcome.

If you cannot obtain any hair with root anywhere – including chest, belly, arms, or back – we regret that we cannot provide our service for you.

The time required for hair collection depends on how many of your pulled hairs contain roots compared to those without.

For example, if 1 out of every 2 pulled hairs has a root, the process will go quickly. However, sometimes it’s also possible that after pulling 10 or even 20 hairs, none have a root. If this happens frequently, we recommend trying a different location for hair pulling.

On average, the entire process, including all steps, should take approximately 30 to 45 minutes. We recommend selecting a time when you can complete the process in peace and quiet for the best results.

Collecting more than 30 good hairs (maximally 80 in one tube) improves the chances of success, as more hairs with roots increase the likelihood of obtaining enough cells.
Additionally, carefully following all steps and thoroughly disinfecting ensures the best results while minimizing the chance of failure.

Yes, hair length matters. Collected hairs should be no longer than 1.5 cm or 0.5 inch, as shorter hairs are easier to handle during processing. There is no minimum length—if you can grab the hair with tweezers and pull it from your skin then that is fine.

Use disinfected scissors to trim longer hairs after you pulled them out, but always ensure you cut the end without the root.

First, put on the included gloves. Spray the hair-pulling area (for the face, we recommend spraying the gloves and rubbing those on the facial area) generously with the provided disinfectant spray and rub it thoroughly.

Als Nächstes besprühst du die Pinzette und reibst sie am Metall ab.
Zum Schluss besprühst du deine behandschuhten Hände und reibst sie aneinander, um vollständige Sauberkeit zu gewährleisten.

Wait a few minutes until everything has air-dried completely before proceeding. Proper disinfection is crucial for maintaining sample quality and preventing contamination.

The kit is generally safe to use if you have sensitive skin or allergies. If you tolerate normal hair epilation (pulling out hairs), you should be able to use it without problem.

If you are unsure about the included disinfectant – which is non-alcohol and water-based, containing didecyldimethylammonium chloride (<1.0%) and alkyl (C12-16) dimethylbenzylammonium chloride (<1.0%) as active ingredients – test a small amount on your skin. Wait for at least one hour to check for any reaction. If preferred, you may also use your own disinfectant. When in doubt, consult your doctor.

For individuals with skin or immune disorders, it is essential to consult your doctor first to ensure that hair epilation is safe for you.

The kit includes an optional, purchasable numbing cream for added comfort. Do not use this cream if you are allergic to lidocaine, prilocaine, or epinephrine. Always consult your doctor if you have concerns about skin sensitivities, allergies, or other health conditions before using the kit.

We recommend using the kit in a bathroom equipped with a toilet and sink. For example, you can place the tube on the sink and sit on the toilet (with the lid closed) while pulling and collecting hairs. For facial hair, you can use the mirror and sink. This setup provides a clean, comfortable, and organized space for the process.

Once you receive the kit, it is best to use it within 1–3 days, as longer delays increase the risk of being unable to obtain viable cells.

Similarly, after collecting the hairs, send the tube back as soon as possible – ideally within 1–2 days – using the pre-paid envelope provided. Avoid storing the tube under extreme temperatures (below 10°C/50°F or above 30°C/86°F) to ensure the sample remains usable.
