We love rubies in particular, there is something special about them. Gemologist Richard Hughes puts it beautifully: A Fine gem is a sexual being. It lives, pulses, throbs.
For us, that being is a fine Unheated Ruby.

A first hand source for top-quality Rubies & Sapphires,KOUROSH was founded more than 25 years ago in Bangkok,Thailand.

Looking forward to serving you at GemGenève 2023!
