Diopside – Merelani Mountains, Manyara, Tanzania
 Sharp-edged and highly lustrous diopside crystal from Tanzania, measuring 1.5 cm x 1.1 cm and weighing 8.5 ct (1.7 grams). The crystallization of the end faces is particularly interesting. The crystal exhibits wonderful transparency/translucency (see video). The color is lime green. A beautiful diopside of very good quality and aesthetic value.
