About Us

B Tree Gemstones is headquartered in Bantawai, Chiang Mai, Thailand. The operation consists of a central office, a lapidary & faceting factory ( 12 years ) and a retail store that is open 7 days a week ( 6 years ).  The primary business is the procurement, faceting and selling of gemstones.  Our secondary business is the design and manufacturing of jewelry.  Although B. Tree Gemstones has customers throughout the world, our business is heavily focused in the United States, where we service more than 200 commercial accounts that include gem dealers, designers and jewelry stores.

The hallmark of our company has been customer service and long term business relationships.  American Charles Riedel (Chap) uses his 35 years of business experience and 20+ years of experience in the gem and jewelry business to guide the team that procures gemstones and rough, and operates the cutting facility.  Subapriya Koonmas (Mam) handles customer service, jewelry design and order fulfillment.  This past year, Bruce Kososki, an American investor and Chad Elmer, who will soon complete his certified gemologist courses at AIGS in Bangkok joined the B Tree Gemstone team. Our company places special emphasis on adding value for our customers.  This begins by buying adeptly from our long time contacts in Sri Lanka, Myanmar, Bangkok, Africa etc., and it continues through gem identification, certification and faceting to produce high quality gemstones that are honestly represented and fairly priced.
