Some of the gold from Olinghouse has a high silver content, and these are sometimes a bit tarnished, as can be seen in this piece.   It was dissolved out of calcite, and still has a bit of calcite under the gold.  Quartz is present as tiny, hair like needles coating the matrix.

JC11840.  Gold.  Mount Gaines Mine (Frenchman Mine) Quartzburg, Hornitos Mining District, West Belt, Mariposa Co., California.  1 cm tall crystalline gold on quartz.  Part of the gold is embedded in the quartz, so it is not glued on.    $325.00   
JC13017.  Grape agate.  Mamuju Regency, West Sulawesi Province, Indonesia.  12 x 9 x 5 cm 472g  $165.00   Nice purple color, and it sparkles throughout the central area.  90% of the material on the market does not sparkle, and the ones with sparkly botryoids are much more in demand.    Much prettier than the photo indicates.   I looked through what seems like tons of this material, and this is one of the few with the sparkly look at a somewhat reasonable price.    An interesting article on the area these are found in by a geologist, is this link:          https://www.indoagate.com/manakarra.html  RESERVED
JC12454.  Grossular.  Jeffrey mine, Val-de-des-Sources, Les Sources RCM, Estrie, Quebec, Canada.   3.2 x 6 cm 21g   $385.00.  Something you don't usually see from the Jeffrey mine, and is in fact quite rare, is a complete floater specimen with no points of attachment.
