"Aye mate, want a rock?" (in the friendly, Kiwi-accented voice of Korg from Marvel Comics)

 (Kiwi-accented voice of Marvel comics' Korg: "Aye mate, ye' want a rock? Yeh may have a rock") 
 Art Room free rocks circle – A popular place in the Art Room is a countertop with a circle
 of “free rocks” refreshed weekly.  The art teacher is a lifetime fan of interesting rocks and
 minerals,  always bringing smooth stones home from the beach or from travels.  Those
 wishing to take away rock/s  --may.  Students have acquired bits of quartz, feldspar, amethyst,
 pyrite, mica, “shipwreck” coal, smoky quartz, sodalite, amygdaloidal basalt, conglomerate,
 agate, coral, Herkimer "diamond," Cape May “diamond,” garnet, onyx, goethite, amazonite,
 fluorite, apatite, jasper, chert, arrowheads, & mystery rocks. Giveaway fossils included those
 of snails, clams, ferns, wood, marine tubeworm clusters, skolithus tubules, trilobites, and
 partial fish.  The gift rocks are fueling an underground school fad among the creatives of
 fabricating wire-wrap/trap jewelry.  Those taking rocks sometimes hear about where they
 came from:  basalt and agate from the shores of Lake Superior in Minnesota, snail fossils
 from the Kansas River out west in Lawrence,  calcite from the Frazier limestone quarry in 
 Harrisonburg, amethyst and smoky quartz from the former Scufflin’ Acres crystal-picking field
 in southern Virginia, smooth stones and Cape May “diamonds” from the Atlantic coast in
 Delaware and Virginia.  Some goethite and petrified wood is from Rockingham County.
