AYAKO SAKURAI × sentoujours.
Special Collaboration "Écrin"
Limited edition jewelry box made with MALHIA KENT tweed and rare colored stone rings to be released.
Limited quantity pre-sale at Hanshin Umeda Main Store POP UP from September 16 (Wed) - September 20 (Sun).
Jewelry brand "Houseki-sho Ayako Sakurai," which proposes a new jewelry experience of "selecting directly from the jeweler," will launch its first collaboration item with "sentoujours.," a jewelry box brand that uses glamorous tweed fabrics also adopted by luxury maisons.
This collaboration will feature the limited-edition jewelry box "Éternelle mini | AYAKOSAKURAI Limited Edition 'Écrin'," specially crafted for Ayako Sakurai's ring collection, and two types of limited-edition rings made with rare colored stones.
These items will be pre-sold at the Hanshin Umeda Main Store POP UP from September 16 (Wednesday) to September 20 (Sunday), 2026.
This special collection offers a unique experience that brings together the brand's cherished value of "jewelry chosen not just for its beauty, but also for who you buy it from" and the "joy of beautifully storing cherished jewelry."
May the time you wear your jewelry, and the time you put it away, both be beautiful.
We believe that jewelry should be a source of joy not only when worn, but also from the moment the box is opened to the time it is carefully put away. It was with this in mind that we collaborated with the jewelry box brand "sentoujours."
Sentoujours meticulously crafts each jewelry box using fabrics from "MALHIA KENT," a premium tweed brand also favored by luxury fashion houses.
For Ayako Sakurai's ring collection, we specially created a jewelry box that emphasizes sizes and specifications to showcase the rings more beautifully, expressing a world where the jewelry and the box are harmoniously integrated.
Item introduction
Éternelle mini | AYAKOSAKURAI Limited Edition
Price (tax incl.): ¥49,500
Materials: Tweed, brass
Color: 1 option
This special jewelry box, exclusively for AYAKOSAKURAI's ring collection, is a luxurious creation using tweed fabric from the premier tweed brand "MALHIA KENT."
We focused on the size and specifications to beautifully showcase the rings, designing even the moment of excitement when you open the box. This limited-edition collaboration item allows you to enjoy the very act of storing your jewelry.
Dogwood Light Amethyst Ring
Price (incl. tax): ¥450,000
Materials: Light Amethyst, Diamond, PT950/K18YG/K18PG
Metal Colors: 3 colors
Introducing a limited-edition light amethyst color to our popular "Hanamizuki" series. The light amethyst used this time is paler than typical amethyst, possessing a fresh, translucent quality. Unlike deep purple amethyst, its gentle, cool hue blends easily with the skin and is perfect for everyday wear. The discovery of this beautiful asscher-cut light amethyst sparked the creation of this limited-edition ring. By combining the soft, translucent purple with the delicate petals of the "Hanamizuki" flower, we have created a special ring that embodies both charm and elegance.
This limited-edition "Hanamizuki" offers a cool and sophisticated look, distinct from morganite.
Luliet Yellow Beryl Ring
Price (tax included): ¥150,000
Materials: Yellow Beryl, Diamond, PT950/K18YG/K18PG
Metal Color: 3 colors
This special yellow beryl ring is crafted based on the design of the popular "Relier" collection. The yellow beryl used here is a special loose stone that Ayako Sakurai finally found after diligently searching for her ideal color and form.
It is extremely rare to find slender, square-cut stones that are so consistently beautiful in color, and we were only able to secure seven such stones this time. It will be difficult to offer stones of the same quality and size in the future, and sales will end once the limited quantity is reached.
To enhance the transparency and beautiful form of the stone, the loose stone is set horizontally. The design is light and refined, making your fingers look neat and long. Despite its delicate appearance, the clear brilliance unique to yellow beryl gives it a subtle presence. It can be enjoyed as a pinky ring or worn on the ring finger for a well-balanced look.

A unique world view made possible by this collaboration

This collaboration is a limited collection where both the jewelry and the box enhance each other's appeal.
About "AYAKO SAKURAI"
Drawing on the purchasing routes and discerning eye inherited from her mother, she began sharing information about jewelry on social media in 2019. She was the first to present the new option that "there are various ways to purchase gemstones besides high-end brands" on Instagram, and is now credited with starting the trend of people identifying themselves as "Instagram jewelers." Her theme is "Towards an era where the freedom of choosing gemstones expands."
She continues to provide a personalized selection experience that emphasizes "who you buy from," through a trinity of in-person sales (Sakurai's "consultative selling" style), Instagram sales (started in 2022), and the members-only e-commerce site "A JEWELRY BOX."
The operation is run by a small, elite team including her husband, who is also her business partner, and a close friend since high school. She has over 25,000 followers on Instagram. Through daily posts, she offers tips to enhance one's perspective on choosing stones and the clarity of one's attire. Serving as her own brand ambassador, she published her first book, "You Don't Need to Pay Brand Premiums for Gemstones," in February 2023.
Her limited-time pop-up shops, which create a different world each time, span from high-end to affordable price ranges. At Shibuya Scramble Square, she recorded a historic 170 million yen (over three days), the highest ever for a pop-up shop at Scramble Square. By providing a sales flow that allows customers to experience "concierge-style service," she delivers a high level of satisfaction. By assisting customers with size, color, and compatibility with existing jewelry, she gently empowers them to "choose a piece of jewelry that will be a lifelong companion, in a way that is uniquely you."
