Our History

In the 1970s, Ban Mo was Bangkok’s ultimate hub for the jewelry and gemstone trade.

Driven by a deep passion, our grandfather established a thriving gemstone business here.

Operating via Letter of Credit, he expanded to serve American G.I. soldiers in U-Tapao.

Among his collection, the Black Star Sapphire quickly became the absolute crowd favorite.

Soldiers believed the Star brought good fortune, protection, and a lifetime of pure peace.

Its most captivating feature is its extraordinary six-rayed asterism appearing under light.

Now, the next generation has brought this meticulously preserved collection back to life.

Under the name Starlight Gemma, we invite you to own a piece of this enduring legacy.

We proudly offer authentic, unheated sapphires that bring hope and prosperity to your life.
