Formation & geological history

Most specimens in this set are silicate minerals formed in igneous pegmatites or sedimentary environments through hydrothermal deposition or secondary silica replacement.

Uses & applications

Used primarily for educational purposes, hobbyist collecting, metaphysical practices, and decorative tumbling/polishing.

Geological facts

This collection features several varieties of chalcedony and macrocrystalline quartz. Rose quartz gets its color from trace amounts of titanium, iron, or manganese, while red jasper contains iron oxide inclusions.

Field identification & locations

Identify by testing hardness (quartz will scratch glass) and examining fracture patterns (typically conchoidal). Common worldwide in varied geological terrains.
