Hello~💛 I'm MAI, the poster girl for MPM Musashi!
Today we would like to introduce a new ring that reflects the Japanese aesthetic sense 💍 [Made in Japan SEIDŌ Ring | Silver 925 Combination Color] ✨
The mirror-polished silver creates a sense of stillness. The pink gold placed in the center creates a sense of movement. These two opposing expressions harmonize quietly on your finger.

💍 SEIDŌ Ring 💍
The material is safe and reliable 925 silver made in Japan .
The sharpness of the mirror finish and the contrast of the organic texture are beautiful, and although it's not too flashy, the ring's "difference" can be conveyed with just a simple gesture.

■ About the JewelryDIANA Lumière Japan brand
Lumière Japan was born as a sub-brand of JewelryDIANA .
JewelryDIANA has always valued the quality and background of Japanese-made jewelry and has continued to work in collaboration with domestic factories to create its products.
On the other hand, due to the recent rise in raw material prices and production costs, it is also true that there is a need for "options to continue delivering Japanese-made jewelry to more people."
That's why we launched JewelryDIANA Lumière Japan .
Lumière Japan is a sub-brand that aims to strengthen price competitiveness . While reviewing materials, design and manufacturing processes, it also places importance on being made in Japan and not compromising on quality.
"Made in Japan jewelry that fits into your everyday life at an affordable price" - that is the mission of Lumière Japan.
Please feel the craftsmanship of the artisans, born from their handiwork.
