About Us

Virendra Kothari established Diagem in 1984 as a loose diamond dealer. With a relentless entrepreneurial spirit, he turned Diagem into a reputable and trusted jewelry manufacturing powerhouse. While working hard to source the finest gems around the world, he utilized his artistic imagination to design exceptional fine jewelry pieces, creating collections that are both timeless and on trend.
