Physical properties

Hardness: 7-7.5 (Mohs scale); Color: Deep fiery red to dark brownish-red; Luster: Vitreous; Crystal structure: Isometric (dodecahedral); Cleavage: Indistinct; Specific Gravity: 3.58-3.75

Formation & geological history

Formed in high-pressure, high-temperature metamorphic environments such as eclogites or peridotites in the Earth's upper mantle. These particular dark red specimens are famously associated with the Bohemian Massif in the Czech Republic.

Uses & applications

Primarily used in jewelry, especially as 'Bohemian Garnet' clustered in vintage settings. Also used as an industrial abrasive and in sandblasting due to its hardness and lack of cleavage.

Geological facts

The name 'pyrope' comes from the Greek word 'pyropos', meaning fire-eyed. These stones were highly fashionable during the Victorian era and are often found in 'pave' style settings where many small stones cover a metal surface.

Field identification & locations

Identify by its characteristic deep red 'blood' color and lack of inclusions compared to other garnets. In the field, it is often found as rounded grains in riverbeds or within dark volcanic rocks. Collectors should look for vintage European settings when evaluating jewelry pieces.
