Customer testimonials

My mother's warmth still shines at my fingertips.
When I held the diamond made from my mother's hair, I felt a strange sense of security, as if someone was by my side. Every time I look at it, my mother's smile and voice come back to my mind.

I wanted to leave something that would be as burden-free as possible for my daughter.
I thought it would be a burden to have children manage graves, so I was looking for a better solution when I came across this service. Even if I'm gone someday, I hope that looking at the diamond will give my daughter some strength in life.

The deciding factor was the sense of security that the project would be completed within Japan.
I was really relieved that I didn't have to send my father's ashes overseas to turn them into diamonds.
It was also great to be able to see actual lab-grown diamonds in the showroom and check the quality.
The staff listened carefully to my thoughts, and I felt from the bottom of my heart that I could leave it to them.

Frequently asked questions
What is the mechanism behind growing diamonds?
The process is very similar to making lab-grown diamonds. We use special equipment to extract the carbon source that forms the basis of diamonds from your precious items, and synthesize the carbon into the core diamond to grow the diamond.
Can diamonds really be made from hair and human remains?
Yes, you can receive our service if the product can extract carbon sources.
Is there any difference from natural diamonds?
The big difference is where they grew up. With the latest technology, it is now possible to recreate the environment in which natural diamonds are produced in a laboratory. The quality, brilliance, and chemical properties are the same as natural diamonds.
How long will it take to complete?
The diamond will be carefully grown in Japan for approximately two months.
How much can I start making one?
Prices vary depending on the item you want and in-store campaigns, but you can start from around 500,000 yen.
Can I order only online?
You can also order online. Please note that if you order online, you will not be able to leave the item at the store or receive the finished product; all items will be shipped by mail.
