Amphibole Cluster with Tabby Formation Brazil

Description

Visual & Aesthetic Appeal
This striking cluster showcases translucent quartz with delicate amphibole inclusions, shaped into unique Tabby crystal formations. The combination of clear quartz, feathery mineral inclusions, and flat, tabular crystal faces makes it a captivating display piece for collectors or creative projects.

Geological Formation & Rarity
Amphibole quartz forms when quartz crystals grow alongside amphibole minerals such as actinolite or tremolite. These inclusions are trapped during crystal growth, producing feathery, needle-like patterns inside the quartz.

The Tabby formation occurs when crystals develop two large, flat faces and parallel sides due to environmental growth constraints, resulting in the characteristic tabular shape.

The combination of amphibole inclusions and Tabby crystal habit is exceptionally rare, requiring precise geological conditions where both minerals crystallize concurrently. This makes each specimen unique and highly valued for collectors.

Origin & Sources
While exact sourcing may vary, such formations are typically found in pegmatitic or metamorphic environments where both quartz and amphibole minerals are present.
