この標本について

A compact, roughly rounded black tourmaline piece presents a broad reflective face crossed by closely spaced lines. The broad black face can catch a strong pale reflection across its surface. The surrounding edges are irregular and visibly rougher.

This marked change is a lighting response rather than evidence of a pale mineral coating. Observable features are the dark body, pronounced linear texture and contrast between a broad face and uneven margins. Closely spaced surface lines cross the principal dark face, with the strongest reflections concentrated along the raised areas.

Locality: Brazil. Weight: 15 g (0.53 oz). Dimensions: 2 × 0.5 × 2 cm (20 × 5 × 20 mm; 0.79 × 0.20 × 0.79 in).

Weight and dimensions refer to the specimen alone, excluding the display base. Any display base shown with the specimen is included.

The specimen pictured is the individual piece offered.

Measurements are seller-recorded; the weight-to-size relationship is awaiting reconfirmation.
