The feelings deep within your heart are invisible
like diamonds and pearls.
Yet they undeniably exist inside you.
That is why ANNA DIAMOND continually listens to those inner voices,
and transforms them into jewelry
—a tangible expression of what lies within.
From words to jewelry.
A gentle reminder of what truly matters, every day.
01. Introduction
ANNA DIAMOND is a jewelry brand founded in Japan by Haruna Mori. Today, the brand is run by Haruna and her husband, working between Tokyo and Paris.
Before founding ANNA DIAMOND, Haruna worked as a copywriter—someone who crafts with words. In an age overflowing with information, she began to wonder if the messages we truly need to hear come not from outside, but from within. Guided by this belief, she set out to capture those quiet “inner voices” often drowned out by the noise of daily life, and transform them into something we can wear every day—words turned into form, expressed through jewelry.
The name ANNA comes from Haruna’s younger sister, who is ten years her junior. It carries a wish that by the time her sister reaches Haruna’s age, the world will be a more hopeful and forward-looking place.
02. Founder
Haruna Mori was born in 1997 in Yokohama, Japan, and is currently based in Paris, France.
After graduating from Keio University with a degree in Aesthetics and Art History, she began her career as a copywriter, creating concepts and copy for both Japanese and international brands. Seeking to expand her form of expression beyond words, she founded the jewelry brand ANNA DIAMOND, where she crafts pieces that translate language and emotion into form.
03. Commitment to Quality
Because jewelry is something to be worn for years to come, ANNA DIAMOND values integrity—even in the parts that cannot be seen.
Each piece is carefully handcrafted in Japan by skilled artisans. Pearl cultivators nurture their pearls with the same devotion one might give to a child. Master jewelers bring them to life with breathtaking precision, transforming each piece into something timeless.
Through countless meticulous steps, a single piece of jewelry is finally completed. We will continue to honor Japan’s craftsmanship and pursue quality that only deepens in beauty and precision with time.
04. Aftercare
From the moment you receive it, your jewelry becomes a companion that walks through life with you. To ensure that you can cherish it with peace of mind, ANNA DIAMOND provides aftercare for every piece.
[Lifetime Complimentary Cleaning Service]
At our Daikanyama ANNA DIAMOND Gallery, you can bring your jewelry in for professional cleaning at any time, free of charge.
We would be delighted to help you nurture its brilliance for years to come.
Please note: additional costs may apply for deep scratches or structural repairs requiring specialized work.
05. Commitment to Materials
ANNA DIAMOND aspires to be a brand that people choose to live their lives with—one that values not only visible beauty, but also the stories, processes, and social impact behind each creation.
To realize this vision, we work hand in hand with trusted Japanese artisans, using materials that reflect care for both people and the planet: reclaimed metals sourced from urban mines, lab-grown diamonds, and uniquely shaped Akoya pearls that have long been overlooked for their individuality.
We also see it as our responsibility to share, with honesty and transparency, the background and journey of how each piece of jewelry comes to life.
06. Giving Back & Educational Initiatives
The name ANNA DIAMOND comes from Haruna Mori’s younger sister, Anna, who is ten years her junior. It carries a wish that by the time Anna reaches Haruna’s age, society will be more hopeful, vibrant, and forward-looking. Inspired by this vision, we engage in a variety of charitable and educational initiatives—believing that even small efforts, one by one, can accumulate into meaningful change.
[Diamond for Peace]
While we primarily use lab-grown diamonds, we remain open to natural diamonds if their supply chains can be fully transparent. A portion of the proceeds from diamond-set jewelry is donated to Diamond for Peace, supporting a future in which all diamonds exist with respect for both people and the environment.
[More Trees]
For jewelry without diamonds, we contribute through the nonprofit organization more trees, donating the equivalent of one tree planted per product. We hope our jewelry enriches not only hearts, but also forests.
[Educational Initiatives]
ANNA DIAMOND values dialogue with the children who will shape the next decade. We have hosted special classes titled “Turning Feelings into Form” at Tankyu Gakusha (Mitaka and Shibuya campuses). For inquiries about lectures or programs, please contact us at info@breval.jp
May the “feelings” that truly exist within you
find their outline — their form — at last.
Take a deep breath.
