Customer testimonials

Voice01

I felt like our two thoughts became one.

When I was registering my marriage, I decided to ask for a diamond made by the two of us, which I would choose together with my partner.
The moment we received the completed diamond, we both looked at each other and burst into laughter with such joy.
Every time I look at it, my feeling that we are going to walk together from now on becomes stronger.

Voice02

A special wedding anniversary that we were able to choose because we were convinced by seeing the real thing.

It's been 20 years since we got married.
To commemorate the milestone, they decided to make a diamond by combining their hair.
By being able to see the real shine in the showroom, I felt that I could trust this place.

The fact that they were carefully raised in a domestic laboratory gave me great peace of mind.
Now, it shines in my hand as a commemorative ring, gently reminding me of the years I've come so far.

Voice03

It is a treasure that allows you to feel the bond between two people at any time in your daily life.

I was truly moved to see a part of the two's feelings crystallize and shine like this.
Every time I look at this diamond, I feel like the time we will spend together and the small memories we will have together are gently engraved inside this treasure, and every time I pick it up, I feel warm.

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.

Can I see the actual product at the store?

Will I receive an appraisal or certificate?
