This gem is from the collection of Dr. Grey Weaver. This gem was cut by Grey. This amethyst is from the famed four peaks mine. Grey and Paul went out there many, many years ago.
This gem may be a little saturated but it has the classic smokey color chevron effect in the gem. It is unusual material and from a well known USA location. Great from the collector; any smear on the table must have come from me wiping it off as under 20x there is nothing but a perfect polish...
