Ha ha... I I know what you mean. the mosquitoes get convincing after a while. As far as I went with the amethyst was a jeweler and a forensic gemologist believe it or not. Didn't want to destroy the object to find out what it was. so then I ask my sister who works at a vetinary clinic to take an x-ray. it appears to have been part of a small crucifix. the the gemologist and jeweler working together to come to the conclusion that it is rose cut amethyst from mexico.. foil set in silver and fits and 18th century profile.
