What Is a Memorial Diamond?

A memorial diamond is a genuine diamond grown from carbon extracted from ashes or hair, using specialized technology and equipment. Like a natural diamond, it has a Mohs hardness of 10.

Each QuenTin memorial diamond can be customized in color, carat weight, diamond shape, and jewelry setting. It can also be accompanied by a certificate from an authoritative gemological institution.

More than a scientifically genuine diamond, it is a deeply personal tribute made only for you.

FAQ

Frequently Asked Questions

In what situations can a memorial diamond be created?

QuenTin memorial diamonds can be created for many meaningful occasions, including remembrance of a loved one using hair or ashes, pet memorials using fur or ashes, engagement or wedding rings made with hair from both partners, baby hair keepsakes, family legacy jewelry made with hair, and other important life moments. If a relationship or memory is irreplaceable to you, it can be preserved forever in a memorial diamond that will not discolor or deform.

How long does the process take?

The production timeline varies depending on the diamond size, color, and customization details. Since its founding in 2018, QuenTin has developed a mature production process and management experience. In general, a white diamond under 1.5 carats with China’s authoritative NGTC certificate takes about 40 days to create, excluding round-trip shipping time. Public holidays may extend the timeline. If you choose optional paid IGI certification, it usually requires about one additional month.

How much ashes or hair is needed? Can they be mixed if the amount is not enough?

For ashes only, around 30g is usually required. For hair, we recommend at least 2g. If one material alone is not sufficient, ashes and hair can be mixed depending on the actual situation.

How can I confirm that the entire process is authentic?

QuenTin values transparency and traceability throughout the process. We can provide production videos, and in-person viewing can also be arranged by appointment, giving every commission greater peace of mind and trust.

Will my sample be handled privately?

Yes. Every sample is handled with care, respect, and strict privacy. We understand that it is not just a material, but a very important personal trust.

Is the entire process safe and environmentally responsible?

QuenTin uses professional equipment and standardized procedures for diamond growth. The entire process is carried out in a controlled environment. We place the highest importance on safety, standards, and environmental responsibility, and do not cause any environmental pollution.

What about custom jewelry design services?

Yes. QuenTin can turn your memorial diamond into a jewelry piece of your choice, such as a ring, necklace, pendant, earrings, or another personalized design. The final cost depends on the design complexity, material, diamond size, and setting method. We can provide a computer-generated 3D rendering for your confirmation before moving into the next stage of production.

My dog's ashes were cultivated into diamonds, which are its own eternity and another continuation of life. There will be no separation and no parting in the future. It looks really beautiful when it shines. I am very lucky to have met such a good store. I can feel that it is made with great care. Thank you Quentin and I am grateful for the fate. I wish it will get better and better and bring comfort and warmth to more furry parents.

I A novel and meaningful wedding ring customization, the style can be customized. It is indeed a real diamond (with an appraisal certificate), and the cultivation process from hair to diamond can be seen in full, very nice! The store staff is very good and professional, answering all questions patiently and responsibly. If you are not considering buying only natural diamonds, Quentin is more recommended. The grade is good and the cost is much lower! Wedding rings are not financial products, what matters is that they are meaningful. And the fire is amazing, super sparkling! Good reviews
