Physical properties

Formation & geological history

Formed through the deposition of silica in igneous rock cavities (geodes). The specific 'Dragon Vein' appearance is usually created by heat-treating natural agate and then rapidly cooling it to create internal crackling, which is then often pressure-dyed.

Uses & applications

Primarily used in jewelry making (beads, pendants), lapidary art, and as a pocket stone for collectors and enthusiasts of metaphysical minerals.

Geological facts

Natural agates are formed over millions of years, but the 'Dragon Vein' pattern is almost always a result of modern enhancement techniques that highlight the natural microcrystalline structure through thermal shock.

Field identification & locations

Identify by its unique crackle or web-like pattern beneath a smooth polished surface. It is commonly found in retail gem shops rather than raw in nature. While the base agate is found globally (Brazil, India, USA), this specific finish is a lab-enhanced product.
