History

Larry Paul Kelley and wife Jo Kelley, owners of the Shelby Gem Factory

Larry Paul Kelley established ICT (International Crystal Technology) in 1970 with Craig Hardy and Tom VanBergen.[1][2] Kelley had worked for Dow Chemical in Ludington and at a factory in Ann Arbor that produced laser crystals.[3] The facility was sited in Shelby because the town had a new industrial park.[4] By 2015, Kelley was ICT's sole owner.[5]

For a time, cubic zirconia was a lucrative product line; Shelby opened factories outside the United States to keep up with demand.[6][7]

A 50-seat theater ran a presentation for visitors[2] and jewelry was sold on site.[4]

The factory closed in 2019 after Kelley was diagnosed in 2017 with Alzheimer's disease. Other issues that contributed to the closing were worldwide competition and online markets.[7] Larry Kelley died on October 24, 2020.[8]

Some of the furnaces burned at 5,040 °F (2,780 °C).[9] Factory tours were discontinued due to liability concerns attendant to the "very high temperatures and extremely bright light" and the unavailability of affordable insurance to cover the risk.[4]

The gems were synthesized in a furnace.[4] The Shelby Gem Factory's diamonds were simulants.[1] The factory also manufactured simulated citrine and topaz, along with other birthstone substitutes.[4]
