Collection: 2025 GTJ Sapphire Festival

✴︎2025 GTJ Sapphire Festival ✴︎

【Part 3】


This month, we have held two major campaigns as "Sapphire Month," and now we are proud to announce the third installment.


We will be holding a special festival celebrating sapphire, the symbol of GTJ and the birthstone of September.


Including newly completed sapphires, and embodying GTJ's philosophy of "bringing high-quality gemstones as close to free as possible," all sapphires will be offered at a special price during the festival period—


"Sapphire Fest Price"


We invite you to discover them.
