At ANNA DIAMOND, every piece of jewelry comes with aftercare.
We want you to enjoy your jewelry with peace of mind for many years to come.

● Lifetime Complimentary Cleaning
At ANNA DIAMOND Gallery in Daikanyama, you can bring your jewelry in for free cleaning at any time.
We hope to help you maintain and nurture its sparkle for years to come.
Please note: For deep scratches or significant damage requiring specialized restoration, additional fees may apply.

These are the commitments ANNA DIAMOND upholds to create jewelry that is not only beautiful, but ethically made.

● Diamonds
Beauty alone is not enough.
We select only high-quality, lab-grown diamonds that are also ethically beautiful.

● Japanese Akoya Pearls
Often called the king of pearls for their exceptional beauty, Akoya pearls are celebrated for their timeless elegance.
Each pearl has its own character — each one beautiful in its own way.
From Akoya pearls with distinctive shapes and hues, we select only those with the finest natural luster.

●Metal
For selected pieces, we use refined metal sourced from urban mines
— recycled materials extracted from end-of-life electronics such as mobile phones and computers.

● Craftsmanship
Every piece is meticulously handcrafted by skilled artisans in our workshops in Yamanashi and Tokyo, Japan.
We take pride in creating with honesty and care, in an environment built on trust and respect.

● Cleaning
To ensure your ANNA DIAMOND jewelry lasts a lifetime, we offer complimentary lifetime cleaning.

● Donations
A portion of our proceeds is donated to the following organizations:

-Diamond for Peace
While we currently use primarily lab-grown diamonds, we aim to one day work with natural diamonds whose supply chains are fully transparent.
To support this vision, we donate a portion of the proceeds from our diamond jewelry to Diamond for Peace, helping to create a world where all diamonds exist in harmony with both people and the planet.

-more trees
For jewelry that does not feature diamonds, we donate the equivalent of one tree planted per piece through the organization more trees.
We hope our commitment will help nurture lush forests and connect to a sustainable future.
