AI-assisted summary
Description from the seller
Natural black obsidian – Possible origin Sardinia, Monte Arci – Large specimen weighing 4.586 kg
Impressive sample of black obsidian, weighing as much as 4.586 kg, characterized by an intense black color and notable vitreous luster.
The specimen presents an irregular, sculptural shape, with broad glossy surfaces, suggestive conchoidal fractures and numerous facets that create fascinating plays of light.
The surface alternates between highly reflective areas and more opaque ones, highlighting the typical features of obsidian, a natural volcanic glass formed by the rapid cooling of silica-rich lava.
Possible origin from Sardinia, Monte Arci area, renowned for its important obsidian deposits, known and exploited since prehistoric times.
The possible Sardinian origin has been suggested by an expert, but it is not accompanied by certification or scientific analysis. The geographical provenance remains to be confirmed.
