About this specimen
Dimensions: 5.5 × 3.2 × 4.5 cm (2.17 × 1.26 × 1.77 in); longest edge 55 mm (2.17 in).
Inner Mongolia helvine at 5.5 cm; a small cabinet piece. The weight was not recorded.
Helvine forms yellow to brown tetrahedra; it is uncommon, and the Chinese skarn material is among the best available.
Inner Mongolia's Huanggang and Chifeng districts produce fluorite, calcite, garnet and rhodochrosite in a lustre and clarity that set the modern standard for Chinese carbonates.
By size it is small cabinet. Condition is otherwise as photographed.
