Diamonds from Ashes or Hair

A cremation diamond is a real, certified diamond grown using the carbon from the cremation ashes or hair of your loved one or pet. It's a personal and lasting way to keep their memory close. Unlike traditional memorial jewellery that simply holds ashes inside a compartment, a cremation diamond is structurally and chemically a real diamond, created from the person or pet you love.

It's a process that mirrors how diamonds form in nature. We start by extracting and purifying the carbon from the ashes or hair you send us. Then, using advanced High-Pressure/High-Temperature (HPHT) technology, we place that carbon into a specially designed environment that simulates the conditions deep within the Earth's mantle. Over time, carbon crystallizes and grows into a real, one-of-a-kind diamond.

From the very beginning, we made a commitment to never be a company that depends on outsourcing the process or buying machines from third-party suppliers. That's why we developed state-of-the-art technology to design, build, and continuously improve our own diamond-growing machines in-house. This level of control over every stage of the process is what allows us to offer diamonds up to 6.29 carats after polishing, in 7 different colours, and at a lower cost than you might expect. It's a combination of serious science and genuine love for what we do.

Yes. Our cremation diamonds are chemically, physically, and optically identical to natural diamonds. Same crystal structure, same hardness (10 on the Mohs scale), same brilliance. The only difference is the carbon source: your loved one's ashes or hair.

HPHT-created diamonds are recognized as real diamonds by gemological authorities like the International Gemological Institute (IGI).

Yes. Aquamation ashes contain the same carbon and mineral composition as traditional cremation ashes, which means they work just as well for diamond creation. The carbon is extracted, purified, and placed under high pressure and high temperature to replicate the conditions that form diamonds naturally beneath the Earth's surface.

At EverDear, all diamond colours and cut options are available, whether the ashes come from aquamation or flame cremation. There is no difference in the quality, structure, or appearance of the finished diamond.

Yes. We can create a memorial diamond from hair, cremation ashes, or a combination of both. Hair is naturally rich in carbon, which makes it a great source for diamond creation. It's also a popular option for honouring a living loved one, such as a parent, partner, or child, or for preserving the memory of someone whose hair was saved before they passed. Only about 2 grams (a small lock) of hair is needed.

We're a proud U.S. company based in sunny Southern California. Our head office and lab are located at 28516 Constellation Rd, Valencia, CA 91355, United States. We serve families across the United States, Canada, the United Kingdom, Japan, Brazil, and over 50 countries worldwide.

You're always welcome to visit us in person. Come see our lab, meet the team, and even view our diamond-growing machines up close. Just reach out to schedule a visit, and we'll be happy to have you.

We offer one of the most comprehensive selections in the memorial diamond industry:

• Carat Weight: 0.1 to 6.29 carats, with transparent pricing at every tier. Looking for something larger than 6.29 carats? Contact us and our scientists will provide a direct quotation tailored to your request.
• 7 Colours: Colourless, Yellow, Green, Red, Black, Pink, and Blue
• 12 Cuts: round brilliant, emerald, cushion, heart, oval, radiant, pear, princess, asscher, marquise, trillion, hexagon, and cat/dog shaped

This range is a direct result of years of investment in proprietary growth and cutting technology.

Yes. You choose a colour family (blue, yellow, green, etc.) and we grow your diamond within that range. However, since the trace elements in every person's ashes are unique, meaning nitrogen, boron, and other organic compounds vary from person to person, the exact shade will be subtly one-of-a-kind.

This is your loved one's individual chemical signature, naturally expressed inside the stone. No two cremation diamonds are ever exactly alike. You will also get a chemical analysis report on the in-house certificate of your diamond.

Of course. We offer a collection of jewellery settings, including rings, pendants, lockets, earrings, and bracelets. Settings are crafted from 14K or 18K gold (Yellow, White, or Rose) and platinum. If you have a specific design in mind, our team can also work with you to create a custom piece. Jewellery settings are priced separately from the diamond, so you have full flexibility to choose what suits you.

Our prices start at HK$ 6,050 for a colourless cremation diamond in the 0.08-0.14 carat range. The final cost depends on the size, colour, and cut you choose. Because EverDear designs and builds its own HPHT machines and handles every production stage in-house, pricing stays consistently lower than most in the memorial diamond industry without compromising quality.

You can place your order online or contact our team to discuss your options and address any questions you may have. Once you're ready, we'll send you a Welcome Kit with secure containers, step-by-step instructions, and everything you need to send us the ashes or hair safely. We only need about 100 grams (roughly 2/3 cup) of ashes or 2 grams (a small lock) of hair.

On average, the entire process takes about 7 to 12 months from the time we receive the ashes or hair. Diamond growth can't be rushed without affecting quality, so the timeline reflects what's needed to produce a stone with proper clarity and structure. We'll keep you updated at key stages, so you always know where things stand.

If you have a special occasion or timeline in mind, let us know. Our lab team can walk you through different possibilities and offer a customized priority process.

We understand how important this is, and we take it very seriously. From the moment you place your order, you're assigned a unique order ID. This ID follows your loved one's remains through every stage of the journey, starting even before we receive the ashes or hair at our facility.

No two orders ever cross paths. Your carbon is worked on separately throughout the entire process, and all tools, equipment, and surfaces are thoroughly sterilized between orders. Our small team prioritizes these logistics above all else, because we know what this material means to you.

When your diamond is complete, you'll receive our Certificate of Authenticity, which includes a full chemical analysis of the carbon you provided as well as an affidavit confirming the diamond was created using that exact carbon.

Yes. EverDear serves families in over 50 countries worldwide. All shipments are insured and handled through trusted carriers. Our team provides guidance on how to send ashes or hair safely from your location.
