Indo-US Business Development Conference Set for Chicago

An Indo-US Business Development Conference will be held at Hyatt Regency O’Hare in Chicago from April 30-May 3.

The objective of the conference is to help increase business between the two primary supply chain partners, the U.S. and India, specifically keying in on new customer acquisition through focusing on underdeveloped retail segments.

The conference will seek to introduce Indian jewelry manufacturing entities to mid-sized national and regional retail chains and the larger jewelry-buying organizations representing groups of key independent retailers.

It will primarily assist Indian exporters to get a firsthand experience of the local jewelry preferences and help U.S. retailers build new sourcing relationships in the jewelry segment.

The purpose of the BDC is to reinvigorate, strengthen and expand GJEPC’s business development efforts and build trusted relationships between India’s key jewelry industry companies and individuals and their counterparts in American markets.

The conference will let both groups listen to important and relevant keynote topics presented for thoughtful discussions between the global colleagues as they work to build new and profitable economic bridges and enhance personal relationships.

Participants will hammer out new and better ways to work together in all aspects of the gem and jewelry trade, including manufacturing, design, production, gem and jewelry material acquisition and retail marketing.

The BDC will share information about the Council’s “Buyer/Seller Matching Initiative,” and showcase the beauty, artistry and production values of Indian jewelry.

Lab Grown Diamonds Unveils World’s Largest Lab-Cultivated Diamond

During the 45th annual Earth Week, Pure Grown Diamonds unveiled the world's largest diamond growing greenhouse and the world's largest lab-cultivated diamond – an achievement, it said, that will help decrease dependency on destructive diamond mining, which is responsible for collapsing eco-systems, disintegrating wild habitats, a century of workers' rights violations and bloody armed conflicts sparked by greed.

"Our physicists have perfected the laboratory process of replicating the Earth's natural crystallization of carbon into alluring, scintillating, sizeable diamonds for the luxury jewelry, engineering, high-tech, precision-cutting instrument and semi-conductor industries," said Pure Grown Diamonds President and CEO Lisa Bissell.
"Pure Grown Diamonds are indistinguishable from mined diamonds, even under a microscope, yet they cost 30 to 40 percent less," she noted.

"Diamonds are a girl's best friend but diamond mining is Mother Earth's enemy," Bissell continued. "We have unlocked the code that will help spare the Earth from further damage and solve the dilemma of rapidly depleting diamond mines."
Academy Award winner Patricia Arquette previewed the record-setting lab-cultivated diamond in Hollywood at a pre-Oscar soirée. It is a 3.04 carat, near colorless diamond – priced at $23,000 compared to an identical earth-mined diamond selling for more than $40,000.

"This is a lab-created diamond, which means there is no blood involved in this diamond," exclaimed Arquette. "It is especially beautiful because no children died for this diamond. There were no slave wages paid for this diamond. There was actually a working wage paid to create this diamond. And, that's about love."
Pure Grown's diamond-growing greenhouse is forecast to yield 350,000 carats in 2015. In 2014, 300,000 carats were harvested from the one-of-its-kind, 200,000-square-foot, $150 million facility. It is owned and operated by Pure Grown Diamonds' Singapore sister company, IIa (2a) Technologies, Pte, Ltd.

Singapore's Deputy Prime Minister Tharman Shanmugaratnam publicly opened the diamond greenhouse several weeks ago.
The United States Federal Trade Commission has concluded that these diamonds have the same chemical, optical and physical properties as mined diamonds, according to Bissell.

Pure Grown Diamonds are available at 147 U.S. jewelry stores in 31 states, the District of Columbia and online at

A one-carat Pure Grown Diamond sells for as little as $3,000. A similar mined diamond sells for more than $5,000.
