Agate altering to Kaolinite (RARE! - old find)

Item Description

Kaolinite has replaced most of a striking agate geode with stunning, dense, sculptural banding. This surreal, otherworldly and RARE large old pseudomorph is from the well-known agate geode producing Rio Grande do Sul district. You can see the bit of remnant sparkly drusy quartz, only in the core of the piece! The striking, cratered moon-like curved back on this fantastic, rare geode pseudomorph adds even more visual appeal. The Salto do Jacui area is well-known as a major source of agate in the form of geodes from Brazil (MINDAT). UNIQUE old-time material from a limited mid-1960s find. Value of such pseudomorph rarity??? A MUST for the pseudomorph, quartz, agate or locality collector!
