JCK Show Adds Dedicated Section for Man-Made Diamonds
A first for the show, it’s called “Lab-Grown” and there are 13 companies signed up to exhibit so far.

Wilton, Conn.--JCK Las Vegas will have a dedicated section for man-made diamonds this year, a first for the trade show.
Called “Lab-Grown,” the section will be located on Bayside, Level 1, near the section for bridge jewelry, the Design Center, the new-last-year JSA Security Pavilion and the new estate jewelry and watch section.
Exhibitors in “Lab-Grown” mainly will be selling loose stones.
JCK Industry Vice President Katie Dominesey said show organizers opted to create a dedicated section for man-made diamonds because of feedback from last year’s show.
Lab-grown diamonds was the No. 1 inquiry at JCK 2017, both at the information hubs on the show floor and on the app.
“We’ve seen the number of lab-grown diamond vendors grow over the past few years and recognize that it is important to have a dedicated space on the show floor while also distinguishing Lab-Grown separately from Diamond Plaza,” she said. “We want to ensure we give these vendors their own destination on the show floor.”
So far, 13 companies are signed up to exhibit in the section including New Diamond Technology, the Russian company known for growing big colored diamonds; Pure Grown Diamonds (formerly Gemesis); and WD Lab Grown Diamonds, the Washington, D.C. company that just grew a 6-carat white diamond.
A full list of the companies exhibiting in Lab-Grown is available on the JCK show website. The section is expected to total 30, Dominesey said.
She said the current plan is to keep the lab-grown section for the 2019 show, which will be back at the Sands.
“If this is an area that customers are looking for, then we will continue it,” she said.
After moving last year to accommodate the Jewish holiday of Shavuot, JCK Las Vegas is returning to its usual date pattern this year.
The show will take place Friday, June 1 to Monday, June 4 at the Mandalay Bay Resort & Casino.
