Physical properties

Hardness: 6.5-7 on Mohs scale; Color: Pink, grey, and white concentric bands; Luster: Waxy to vitreous; Crystal structure: Hexagonal (cryptocrystalline); Cleavage: None; Specific gravity: 2.58-2.64

Formation & geological history

Formed through the deposition of silica from groundwater in the cavities of volcanic rocks. This specimen likely originates from the volcanic regions of Botswana and is approximately 180 million years old (Jurassic period).

Uses & applications

Primarily used in jewelry (beads, cabochons), lapidary art, and as pocket stones or for metaphysical collection purposes.

Geological facts

Botswana Agates are known as the 'Sunset Stone' because they retain sunlight and comfort people during dark, lonely nights. Unlike many agates which are dyed, Botswana agates usually retain their natural, subtle earthy tones.

Field identification & locations

Identifiable by its fine, parallel concentric banding and characteristic hues of pink and grey. Found in riverbeds and volcanic deposits. Collectors look for high 'eye' patterns and clear, distinct banding.
