within the days two people build together.
What truly matters is not the splendor of the ceremony,
but how you gather up the light hidden
in the life that begins that day.
The most certain happiness, the kind you can feel,
lies quietly in the days close at hand.
Every ring was born
by giving words to the “philosophy of light” that
ANNA DIAMOND holds dear,
and letting those words take form as jewelry.
Through custom order,
we craft a ring that belongs to you alone.
The everyday light that floats like air.
A ring for two that rests so gently on the skin
you forget you are wearing it.
It stays out of the way of hands washing dishes,
hands at work, a touch to a child’s cheek.
Like a light that remains at the center of daily life,
it is a ring that dissolves into the everyday.


Life has its peaks. It has its valleys.
Yet no single event
can be measured from one face alone.
Even when one summit is wrapped in the dark of night,
the other is lit by the morning light.
Into a ring with two faces,
we set the resolve to always seek out
the side where the light falls.



Every day is made of repetition.
Within a sense of life worn smooth by routine,
let us catch the light we might overlook
with the fresh feelers of the heart.
It is this very posture
that weaves two lives richly together.
A ring that holds the resolve
to discover the light of each day, actively.



Starting from the collection, toward a single ring that is truly yours.
With HIKARI, you can choose from four customizations.
Every ring is set with a single diamond. You are free to choose where it sits, on the inside, the outside, and more. After your purchase, you may also add diamonds through an optional service.
You may choose your preferred width from 2mm or 3mm. The 2mm ring has a delicate impression, while the 3mm ring carries the presence of the metal. Choose the one that sits naturally with your everyday attire.
Choose between a mirror finish, clear and composed with its light, and a matte finish with a softer character.
Choose the color of the metal from silver (platinum 950), gold (18K yellow gold), or black (platinum 950).

ANNA DIAMOND stays with you for years after the ring is in your hands.
We offer warranties for peace of mind and options tailored to your preferences.
We feel a small unease with the idea that the moment of marriage is the happiest point in life, and that it is precious to seal that state away forever. Your relationship will keep changing, gently and for the better, in the years ahead. Marriage, too, is one waypoint within a long stretch of time. And so, rather than vowing to stay unchanged, we chose materials that grow with the years, so that you can cherish the changing itself. What truly matters is not the splendor of the ceremony but the daily life that begins that day. How the two of you find and gather up the small light hidden within that life. We have designed every detail of the ring to accompany that spirit.
We have prepared materials whose expression shifts with the years. A matte finish whose metal deepens little by little through daily life, and a ruthenium plating that gradually settles into the skin. This graceful aging is proof of the time you have spent together. Rather than vowing to stay unchanged, you can cherish a deepening relationship alongside the ring’s own change.
Every metal we use comes from urban mining. Because it is melted back into pure metal before being reborn, its strength is no different from newly mined material. A material that keeps circling from past to future, changing shape, mirrors the bond the two of you will build over time.
Every ring is set with a carefully selected lab-grown diamond. However much the surroundings change, a single point continues to give its quiet light at the center. The diamond can be placed wherever you like, on the outside or the inside.
Through custom order,
