Spessartine on quartz
description: <p style="text-align: justify;">LOCALITY: Lavra Navegadora, Penha do Norte, Minas Gerais, Brazil <br /><br />2 1/2" across <br /><br />Although I have seen much larger specimens of spessartine from this locality, this is more desirable than many of the larger ones for the following reasons: <br /><br />(a) It is gem quality. Most other specimens from this locality are opaque. <br /><br />(b) It is completely free of damage on both sides. Many other pieces from this locality are damaged. <br /><br />(c) It is colorful. Many other pieces from this locality are so dark that they are almost black. <br /><br />(d) The luster is high. Most other specimens from this locality are not as lustrous. <br /><br />(e) The spessartine has grown around a core of quartz crystals (see photo). Aside from the quartz crystals that the spessartine group is "wrapped" around, there is no evidence of contact between the spessartine with host rock or any other crystals. Hence, this piece appears to be a floater. <br /><br />Interestingly, the small quartz crystals in the foreground of the photo are sharp and do not appear to be etched. Maybe there was more than one generation of quartz crystal deposition and more than one generation of spessartine deposition within the pocket that gave rise to this piece.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Photo by Jeff Scovil </p>
