[Collection]
“Unique Akoya Pearl Collection”
A collection of Japanese baroque Akoya pearls that would usually never see the light of day.
For pearls, as for people, fitting a given mold is not everything.
Set appearances aside and stay true to your own color and shape.
Beauty does not need to be bound by a single rule.
Everyone is different, and everyone is good.
[Our Philosophy]
The Akoya pearl collection is made possible by our designer Mori, who visits Japanese pearl farming regions each year, building relationships with pearl farmers and selecting each pearl one by one.
Raised like children by skilled farmers over three to five years, the pearls truly differ in color and shape, one by one, just as Misuzu Kaneko wrote in her poem, "everyone is different, and everyone is good." Under conventional, uniform grading standards, these expressions can be judged negatively. In this series, we choose to place them at the center.
For pearls, as for people, we believe fitting a given mold is not everything. This piece is for those who want to set appearances aside and stay true to their own color and shape.
At ANNA DIAMOND Gallery, our store in Daikanyama, you can choose each pearl for your jewelry yourself. Among pearls of many expressions, the one you meet as a destined encounter will surely stay close to you, watching over you for many years.
*For online orders, our brand team carefully selects the pearls used for your piece.
Sizes are Japanese ring sizes. If in doubt, we recommend your exact size or half a size up. Ring sizer rental →
