Beschreibung

Locality: West-central Bongolava region, Madagascar

Description: Kambaba Jasper, also called crocodile jasper, is a dark green and black stone patterned with round, orb-like markings. These pieces are tumbled and polished smooth.

About the Stone: Kambaba Jasper is a volcanic rock, not a fossil. Thin-section and XRD analysis by the German gem lab EPI identified it as rhyolite made of quartz, aegirine pyroxene and feldspars; the dark orbs are clusters of radiating amphibole needles.

Chemical Composition: Rhyolite: quartz, feldspars and aegirine pyroxene, with amphibole orbs (mixed rock, no single formula)

Approximate Size for 1 piece: 25mm x 25mm x 20mm
Approximate Weight for 1 piece: 16g

Quantity: 1pc
