Rare Kidwellite Spheres w/ Rockbridgeite & Beraunite (Thumbnail) - York Mine, AR For Sale

An exceptional, old-stock American rare phosphate specimen featuring smooth, pale mint-green botryoidal Kidwellite spherules nestled cleanly inside a protective, fibrous terracotta-orange Beraunite pocket from the famous York Mine, Polk County, Arkansas.

Polk County, Arkansas is world-renowned among rare species collectors as the co-type locality region for Kidwellite (named after Dr. Albert L. Kidwell). While Kidwellite often occurs as thin coatings or flat cross-sections, three-dimensional specimens showcasing intact mint-green spheres cradled inside a contrasting Beraunite vug are extraordinarily scarce.

This piece displays a stark, high-contrast visual arrangement: smooth, porcelain-like sage/mint green Kidwellite lobes framed by a thick, fuzzy hood of bright rust-orange fibrous Beraunite micro-crystals, separated by a thin dark band of Rockbridgeite.

A standout centerpiece acquisition for rare phosphate specialists, Arkansas locality collectors, or systematic thumbnail cabinets seeking exceptional three-dimensional vug presentation. You will receive the exact specimen pictured.
