Customer testimonials

Voice01

The joy of feeling the bond with your pet.

I was a little worried when I heard that it was made using advanced technology, but they explained it to me in detail and put me at ease.
The completed diamond shines more beautifully than expected and blends into everyday life as a proof of love.

The explanation was thorough and made me feel at ease.

It's amazing how beautiful diamonds can be created from the hair of your beloved dog that you've spent so much time with.
Every time I wear it, I am reminded of the warm memories and kind gestures of that day, and my heart is filled.

Voice03

Love that can be felt in everyday life.

I wear it as a ring every day. Not only is it a special treasure, but it also gives you the peace of mind that your dog will always be by your side.
