Euclas – Ecuador, Rio Grande do Norte, Brazil
 A wonderful euclase thumbnail in very good quality with extremely rare and sought-after blue inclusions. The fully crystallized and recrystallized euclase has a decent size of 1.9 cm x 1.1 cm x 0.7 cm. The crystal is double-terminated and features an intergrown double-hedral quartz crystal.
 Highly sought-after and aesthetic collector's piece from Brazil.
