Amethyst Shipping & Storage existed as a fictitious business on New Cov. Garm Bel Iblis founded it during the time of the Galactic Civil War. It operated a storage facility in Ilic; this is the location where Han Solo initially encountered Bel Iblis' top subordinates, Sena and Irenez. Solo was separated from Council-Aide Tav Breil'lya when he entered this building just prior to the attack on New Cov.
Amethyst is a type of quartz that can be found in the real world.
