Physical properties

Formation & geological history

Formed via hydrothermal precipitation in veins, vugs, or cavities where silica-rich fluids cooled and crystallized over thousands to millions of years, creating elongated parallel crystal structures.

Uses & applications

Used primarily as decorative display specimens, in mineral collections, metaphysical practices, and as raw material for lapidary work. Pure quartz is also widely used in electronics and glass manufacturing.

Geological facts

This particular cluster exhibits a striking parallel growth habit often called 'candle quartz' or 'pineapple quartz' where multiple elongated quartz crystals grow parallel to each other around a central core or axis.

Field identification & locations

Identified by its hexagonal prism terminations, hardness (scratches glass readily), and prismatic parallel crystal alignment. Commonly found in pegmatites, hydrothermal vein deposits, and quartz cavities worldwide.
