Type Locality. Yellowish-green spots in aegirine syenite.
Yellow patches in matrix. Ōmi is noted as the Type Locality but it is not clear exactly where. Probably Ōmi River rather than this locality.
Yellow calcite with bluish-white fluorescence (Convoy) and a green afterglow that takes a few seconds to fade. Colours are not exact in photo (iPhone). Also, compared to the many many calcite specimens from Chenzhou in Mindat, this is atypical. There is a large variety of forms, but not like this...

Gemmy rich emerald-green fluorite octahedrons, to 15mm on edge, cover the matrix plate 75x70x25mm. This colourful two-generation fluorite is from a small 2016 find near Yiwu City, a very obscure locality in Zhejiang Province, China. Scattered secondary overgrowths of clusters of purplish-grey, frosted, stepped-growth cuboctahedrons add contrast. Some of the...
