A beautiful partial
fluorite crystal from the recent find at the Xiayang Mine (sometimes referred
to as the "Yongchun Mine.). While the vast majority of specimens from here
are a duller gray green, very few of them have rich blue hues which when
combined with green and yellow zones lead to an incredibly saturated, rich
This is not a complete
crystal and there are a couple blemishes, but it displays well from one side (that is, it looks reasonably complete from that angle) and it has a somewhat darker blue green color. I have not seen this
color from anywhere else-- not even the brightest blues from
Southern Illinois have the same glow that is added by the combination of
green, yellow, and bluish zones that some of these crystals have.
The color of these pieces
varies strongly with lighting-- under incandescent light they look grayish and
undersaturated. To be best appreciated, they need the equivalent of
indirect sunlight. What is depicted in the pictures is what you would see
if the piece were placed next to a window on a cloudy day.
