Item Description

A superb example of the Purple Sage Chalcedony (sometimes called Amethyst Sage Agate) from the Bilk Creek Mountains in Nevada. This material ranges in color from a soft silvery-lavender to a rich purple hue. The vast majority of these stones (approximately 90%) are found with dendritic inclusions. The remaining 10% have the highly coveted rich "Purple Sage" hue, and only 10% of THOSE stones are free of inclusions, so these stones literally represent about 1% of all the material mined. This particular gem is a gorgeous "Oval" Cabochon cut stone with a very attractive purple hue and excellent internal translucency. As you can see, it's free of dendritic inclusions and looks great both in transmitted light and reflected light. If you've been looking for a top Purple Sage Chalcedony, do not let this one get away, as they are difficult to find this size and quality.
