Welcome to JEX

Jewelry that has been stored away and never used, but there is someone out there who would be happy to use it... JEX is a bridge between the two.

The name "JEX" comes from "Jewelry Exchange".
When you buy new jewelry at JEX with the sale price after the transaction is completed, you are "exchanging jewelry that you no longer use for jewelry that you want to use.

We hope you will enjoy the real pleasure of buying and selling jewelry through the JEX brokerage system.

History of JEX

History of JEX

The founder of JEX, Toshio Fujimoto, had the idea that there was no way to improve the reality that jewelry is expensive when you buy it and surprisingly inexpensive when you sell it. He came up with the idea of creating an "intermediary market for the buying and selling of jewelry"...and this was the solution he found.

After much trial and error, he came up with the idea of charging an intermediary fee from both the seller and the buyer when a transaction is completed.

In this way, JEX's jewelry brokerage system was created to not only provide a place to meet new owners, but also to make the price difference between buying and exchanging as small as possible.

In 1990, JEX opened the Osaka Ekimae Branch as Japan's first full-scale jewelry brokerage market, followed by the Tokyo Ginza Branch in 2000.

Since its establishment, JEX's gem brokerage system has been welcomed by many people, sometimes even from overseas, and we feel that the vortex of joy is steadily expanding.
