In 1932, the story of Diamond Gallery began with a family of overseas Chinese immigrants who settled in Chiang Mai. Bringing with them exceptional craftsmanship in goldsmithing and fine jewelry from China, Mr. Peng Lim and his wife founded Ngoun Lee Seng on Chang Moi Road—one of Chiang Mai’s most important business streets. This establishment became the first gold and gemstone jewelry store in Chiang Mai and Northern Thailand.

The Beginning of Timeless Elegance
With a dedication to crafting gold jewelry, diamonds, and gemstones of exquisite beauty and flawless detail, the store quickly earned the trust of noble families, government officials, and provincial governors across Northern Thailand. It became a hallmark of luxury and fine craftsmanship.
