Appearance and Backlit Presentation
Backlighting is used to reveal the specimen’s colour response and translucent visual character. The changing appearance shown in the photographs provides an important part of its presentation, allowing the internal visual qualities of the piece to be appreciated more clearly than under ordinary front lighting. This makes it an engaging addition to a display cabinet, shelf, desk arrangement or dedicated mineral collection.
The Grade A description identifies the supplied quality category. Colour and translucence are key features of the presentation, while the opalised marcasite identification gives the specimen its specific mineralogical character. Please refer to the photographs for the complete view of the piece and its appearance under the featured lighting.
