ID: CC21231
Mount Teneriffe forms part of a mountain chain in western Washington state, east of Seattle, and is a locality known for well crystallised Quartz found amongst a breccia on its north face.  This interesting small miniature has several transparent terminated Quartz crystals covering a sawn granitic matrix.  The saw cut provides a good and stable base and is not apparent once displayed.  The dominant feature is a roughly 90 degree offset pair of gemmy Quartz crystals, measuring 2.7 and 2.4 cm long from the common base.  These are noted on the accompanying old label as a Japan Law twin (typed “Japanese twin”), but I feel this must be treated with caution.  It could be, but the re-entrant angle does not appear close to meeting the criteria of this twinning law.  Whatever, it is a beautiful pair of transparent and gemmy Quartz crystals, of the variety Rock Crystal.  This specimen is from the Josef Clemente Collection of southern Germany.
