Ex. Lillie, Ross

One of the oldest pieces in the collection, this one is subtle and historic, but also beautiful. Aesthetically emplaced on a smoky quartz druse are a cluster of lustrous and translucent, rich lavender colored fluorite cubes, to 2.5 cm across. The second largest crystal has minor damage to a corner but this is still a very nice specimen. According to the Ross Lillie label, this was mined in the 1930's and is an "excellent, aesthetic combination from extremely rare location. Note two generations of quartz. Smoky phase is later and fluoresces due to hydrocarbon inclusions. Also, growth irregularities on spar surface are possible interference from hydrocarbons." RCL 132
