GILALITE in QUARTZ
This beautiful included quartz specimen is polished all around , to reveal the rich gilalite inside. This is an extremely rare mineral. It is not a natural crystal specimen, due to teh polishing, I admit, but it is nevertheless significant as heck. Also, there is enormous investment potential in that one could TRIM the specimen into numerous slices, each a salable example of this rare species included in quartz. It is said to be the finest specimen of only 5 that were found. Gilalite is a copper silicate hydrate. To quote Mineralogy of Arizona, abundant as green to blue-green coatings or thick botryoidal crusts on fracture surfaces in the rock, or replacing diopside. It had not to our knowledge been found in this form before! 7.1 x 4.7 x 2.7 cm
