Rio Pearl is a producer of the finest White and Gold South Sea Pearls in the Mergui Archipelagos of Myanmar. Our mission is to cultivate the most beautiful gems in the world, while protecting the environment that the oysters inhabit.


Our founder, Mr. Johnny Cheng started his jewelry business as a retailer at the Hyatt Hotel in Tsim Sha Tsui. He moved into the wholesale pearl business in 1983 selling Freshwater Pearls and Akoya Pearls.


As business expanded, our headquarters moved to Railway Plaza in Tsim Sha Tsui. Rio Pearl attended trade fairs across the world including the United States (Las Vegas, Miami, New York, Tuscon), Baselworld, Germany, Japan, Taiwan, Malaysia, Vietnam, Thailand, Cambodia, Dubai, Indonesia, Singapore. Rio Pearl specialised in creating everyday casual jewelry as well as one-of-a-kind masterpieces.


The Rio Pearl Factory opened in 2005 in Shenzhen, leading to new innovations and extravagant pieces for the next decade.
