Baryte

Baryte from Oraparinna Baryte Mine, Oraparinna, South Australia, Australia, measuring 70 × 58 × 36 mm and weighing 271 grams. The named mine gives this specimen a direct locality connection with the mineral it represents. It is a useful South Australian example for a collector who enjoys following familiar species through their individual Australian occurrences.

Baryte is barium sulphate, a mineral notable for its relatively high density. The heavy barium in its composition contributes to that density, giving it an interesting physical contrast with similar-looking minerals from other chemical families. Baryte's many occurrences also give collectors opportunities to compare locality material without losing sight of the shared mineral identity.

Pale, partly translucent tabular crystals overlap across the face, with warm honey-toned areas between them. The broad reflective surfaces give the group depth as the viewing angle changes. A close look is worthwhile: the stepped edges and intersecting plates offer a more detailed study than the specimen's quiet overall palette might initially suggest. This specimen comes from the David Vince Collection. Its appeal is a straightforward but worthwhile combination of a defined South Australian source and a well-documented individual piece. Within a Baryte collection, it supplies an Australian locality reference; within a regional collection, it represents a mineral closely connected with the named mine and its place in the collecting landscape.
