Item Description

Sculptural and exotic large 2-sided, lustrous, polished agate slab from Rio Grande do Sul, Brazil.

The variably-colored matrix on the bottom adds even more pizzazz. 398 grams mass. Backlighting really accentuates the colors and details of this outstanding large agate slab. VERY unexpected included Hyalite Opal in the agate with neon-green SW UV fluorescence! A REAL bonus. Ex Jack Halpern Collection No. 3423 of San Francisco.
