Rorschach Test Inclusion
What do you see?
Bent over his microscope to peer into a customers amethyst ring, Wink Jones blinked and looked again. It was just the darndest thing, he says. I was looking at a perfectly formed perfume bottle, complete with a fashionable stopper. What Jones, of Winfields, Boise, ID, really saw was natures surprisingly realistic imitation of a human creation. The inclusion comprises a symmetrically arranged cluster of goethite needles, a form of titanium oxide. This inclusion can occur in most forms of quartz, particularly rock crystal and amethyst.
While Jones saw a perfume bottle, other viewers see a shaving brush or a broom. What do you see?
Despite the mounted amethyst being well-worn and the facet edges heavily abraded, the inclusion can still be examined easily using 30X or greater magnification. For the needle groups to show up in stark contrast, a combination of oblique and dark-field lighting was used here. The amethyst was photographed at 45X.
