Pursuing precision down to 0.01mm
A unique and unparalleled craftsmanship that uses no rubber molds whatsoever
In the typical mass production process of jewelry, casting using rubber molds is performed; while it excels in production efficiency, an error margin of ±0.2 to 0.4 mm is unavoidable, limiting the expression of delicate details.
Therefore, we thoroughly maintain an accuracy of "±0.01 mm" and adhere to a unique manufacturing method that does not use rubber molds at all. This is our commitment to perfectly reproduce delicate details such as the cat's outline, expression, and limbs.
The jewelry of Atelier Milanese Japan is not merely an ornament but a "work that conveys the warmth of life."
A deep affection for cats and a spirit that allows no compromise on beauty dwell in each and every form.

About this page
The world’s first online boutique combining cats and engagement rings
[ATELIER MILANESE JAPAN]
For all who love cats, and for the two who will walk through life together.
We at ATELIER MILANESE JAPAN have launched the world’s first and only online boutique that blends “cats” with “engagement rings.”
We have captured the cat’s grace, charm, and loveliness directly into the design, elevating it into an engagement ring that symbolizes the future you will share.
All the rings introduced here are engagement rings inspired by cats.
Unlike ordinary engagement rings, the very essence of the cat lives within each ring.
Since ancient times, cats have fascinated people as mysterious, affectionate, and sometimes free-spirited and whimsical beings.
We hope your future together will be one of mutual support, closeness, freedom, and flexibility.
With that wish in mind, the cat engagement ring was born.
The sight of two cats joining forces to hold a diamond,
a cat wrapping its whole body around a diamond,
a small cat gently nestled beside a diamond—
each design carries a story where the cat and your future intertwine.
Our cat engagement rings are not merely “rings with a cat motif.”
To fully express the cat’s elegant movements and expressions, we have painstakingly refined every detail, including the eyes, nose, and mouth.
The life shining in the eyes.
The supple form of the paws.
The beautiful curve from the back to the tail.
Bringing these to life as jewelry requires the advanced skills of master craftsmen.
Using precious metals such as 750 gold and Pt950 platinum, delicate carving and polishing realistically convey the warmth of the cat.
Because this unique theme combines cats and engagement rings, we pursue a level of precision that could be called a work of art.
