Gembridge Launches Trade 
Promotion with Chinastone in US

(PRESS RELEASE) NEW YORK — Gembridge, a digital coloured gemstone trading platform, is launching a trade promotion for high precision, machine-cut calibrated stones with Bangkok-based manufacturer and AGTA member Chinastone in the U.S. market.

Gembridge will make precision calibrated stones supplied by Chinastone easily available to the U.S. trade, including jewellery manufacturers and designers, with a door-to-door global service.

“Gembridge’s exclusive partnership with Chinastone will create a superb new opportunity to source expertly manufactured calibrated coloured gemstones in the jewellery and watch sectors,” said Gembridge Chairman Tony Brooke.

The promotional campaign, supported by social media, will drive orders for calibrated gemstones manufactured by Chinastone and boost trade registrations on Gembridge.

The promotion will put samples directly into the hands of trade members in the U.S.

The first 500 who successfully register and join Gembridge receive a free pack of 10 sample stones worth up to US$50. The campaign will promote this cost-effectively through email and social channels.


Earlier this year Gembridge signed a groundbreaking agreement with Chinastone to exclusively deliver digital sales of the manufacturer’s gemstones, which is expected to boost e-commerce to the global small and medium enterprise (SME) market.
Chinastone is a leading manufacturer of high-precision cut gemstones. Its clients include the world’s most admired luxury jewellery and watch brands, independent line jewellers and watch manufacturers. They rely on Chinastone’s comprehensive range of melee-sized calibrated natural coloured gemstones and Chinastone’s real time availability of over 20 million stones.

Gembridge is the sole manager of Chinastone’s digital marketing and sales channel, focused on the global SME market, which currently accounts for a significant portion of Chinastone’s annual turnover.

“We are excited to be opening up this new digital sales channel with Gembridge and making our high precision, machine-cut calibrated stones available to thousands of small to medium sized manufacturers and jewellery designers across the U.S.,” said Mr Li Chongjie, the Founder of Chinastone.

Wilkerson Testimonials | MSG Jewelers

Wilkerson Takes the Worry Out of Closing

MSG Jewelers has always treated its customers like family. When owner Mike George decided to retire and close the doors of his St. Louis, Missouri jewelry store, he selected a company to manage his going-out-of-business sale that treats its customers like family, too. That’s why he chose Wilkerson. “Wilkerson was able to do all the things that we needed,” says George. In the end, the bittersweet store closing was so much easier with Wilkerson at the helm. From marketing to pricing to inventory, Wilkerson does it all. “It’s a package deal,” says George.
