新作ダイヤモンドジュエリー

Thank you for always choosing 440showroom.

Today, we've added new jewelry to our online store.
We are introducing items that were well-received at our 2025 Spring/Summer exhibition and showroom, as well as jewelry perfect for the upcoming season.

Our popular "Water Lip" series now includes new opal and turquoise pieces, in addition to the previously sold-out onyx and malachite.
We have a wide selection of jewelry that is sure to excite you.

Some items are one-of-a-kind or limited in quantity, so be sure to browse early.
