The diamond and gems pavilion at 3rd CIIE doubled its exhibition area to 20,000 square meters this year, accommodating more than 200 exhibitors from 33 countries and regions. Some rare items include a bathtub made from a half-ton of the gem stone malachite, a scepter with 3,003 diamonds and an 88-karat black diamond, making the pavilion the shiniest at the show.
