Thank you for always using MPM Musashi.

■ Regarding the items subject to price revision

The following products are subject to this price revision. The affected products are listed on their respective pages.

• Japanese-made silver products from the JewelryDIANA brand and the new brand JewelryDIANA Lumière Japan.

■ Background of the price revision

All silver products from JewelryDIANA and Lumière Japan are made to order at factories within Japan.

We have received official notification from the factory regarding price revisions due to rising raw material costs and increased processing costs.

While we have strived to maintain prices as much as possible until now, in order to continue our domestic production system and maintain quality in Japan, we are unfortunately planning to revise the prices of all our Japanese-made silver products .

■ Scheduled date for price revision

Monday, February 16, 2026 → Saturday, February 28, 2026

*Details of the revisions vary depending on the product. We are covering the increase in precious metal prices, so you can purchase these items at a great price for a limited time only! ✨

■ Regarding orders placed at the pre-revision price

Orders will be accepted at the current price until February 27, 2026 (Friday) , before the price revision.

Since all JewelryDIANA products are made to order, there is a time limit for orders placed at the previous price.

If you are considering purchasing any of our products, we recommend placing your order as soon as possible.

*This is your last chance to consider our products before the price revision.

At MPM Musashi, we will continue to work in cooperation with Japanese jewelry factories to ensure honest craftsmanship and consistent quality.

We kindly ask for your understanding.
