Emerald on calcite
description: <p style="text-align: justify;">LOCALITY:  Cozcuez Mine, Columbia </p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">2" across </p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Ex Cal Graeber collection. <br /><br />I bought it from Stuart Wilensky in mid 2009. I first saw the piece in Cal's collection in early 1998 when I visited him at his home in Fallbrook, California. <br /><br />It is an elite emerald miniature since: <br /><br />(a) The emerald crystals are intensely colored</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(b) The edges and vertices of the emerald crystals are pristine and this is event even under magnification.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(c) The luster of the emerald crystals is as high as polished glass.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(d) The crystal to matrix ratio of the specimen is pleasing since the emerald crystals are not "overpowered" by the calcite crystals that they are perched on.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(e) The piece has a symmetrical and organized appearance about it rather than a "busy" appearance.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(f) Emerald crystals are only found on "flattened", grey calcite crystals at Cozcuez. At all other worldwide emerald localities, the crystals (when not loose) are on a comparatively ugly rock matrix. Hence, this piece displays a rare mineral combination.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(g) The emerald contrast against its matrix.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">(h) The piece has been prized by others who are important identities in the international mineral specimen trade. Stuart Wilensky is America's top dealer in elite mineral specimens and I have traded with him since 1992. Cal Graeber is also one of America's top dealers and his appraisals of collections have been accepted for court purposes in the United States. He is also a geologist and holds a Masters Degree which is relevant to his profession. I have traded with Cal Graeber since 1989. <br /><br />Emerald specimens of this caliber will always be rare since crystals are often destroyed for their facet rough. The small quantity of matrix emerald specimens that have come to market have only been exported from Columbia mainly post 1980.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Now in the collection of Professor Stephen Smale  </p>
