especially in fine quality specimens
This is ostensibly one of the finest crystallized Rutile specimens ever seen from any Brazilian locality for the simple fact that it is GEM GRADE Rutile in addition to being superbly crystallized
but the crystals from around Mogok are the largest and finest known specimens of the species ever found
The luster is superior to most from Siglo XX
The crystal shows an interesting and eye-catching fluorescence under UV light with shades of pink
Polybasite
(pseudomorph after Acanthite) New Jersey especially in fine quality specimensHere we have a wonderful cabinet sized display specimen featuring fine quality, sharp, dark grey colored, pseudo hexagonal crystals of Polybasite on all sides. At first glance, the underlying matrix appears to be crystals of Acanthite, but upon close inspection, you can see hundreds of tiny Polybasite crystals on the surface, which combined with the somewhat skeletal nature of the Acanthites makes be believe that these could actually be pseudomorphs
