Collector’s Piece: "Arrow" Calcite with Rainbow Iridescent from Qinglong Mine

Dimension: 8.7cm x 7.6cm x 3.4cm
Weight: 273g

Calcite of this kind started emerging from a one-time-find in the area near Qinglong Mine in early 2019, where most of the specimens excavated were either heavily damaged or not as gemmy as this piece. This example is certainly one of the best I have seen, the color is so vibrant, the Calcite crystals are so gemmy in excellent condition and of a great size – 8.7cm in length.  Exceedingly vitreous, divergent sprays of gem quality Calcite crystals in an eye-catching amber yellow color intergrown to form this fan-shaped cluster. It exhibits miraculous rainbow iridescent and an arrow shaped termination, so stunning! This species of Calcite exhibit green fluorescence under UV lighting (365 nm) and a long phosphorescence emission as shown on my blog page. It is very difficult to capture its beauty on photos, the real piece is way more beautiful! A high quality display stand made of pure copper and acrylic as pictured is included in the price.
 
When these came to the market they were quickly snapped up and disappeared. I would say these are not just Calcite but rather have elevated to unique in mineral collecting and are immediately recognizable!
