A friend of Tammy's has a chunk of amethyst crystals and was curious as to what the rusty orange highlights on the crystals might be caused by. I'm assuming it's some sort of iron oxide deposit leftover from when the amethyst crystals were created within the geode. I know that impurities of iron are responsible for turning the colorless quartz into a lovely purple amethyst. Has anybody else seen these rusty highlights in their amethyst specimens? Cheers. -Ken '

Hello, I am completely new to fossil hunting. I recently found this in my back yard while filling in a hole that had been dug a few months back. I don't know if it's fossil, natural formation or garbage. I'm hoping the Fossil Forum members can help ID it for me. It was found in the far west part of the panhandle of Florida. I know the ground here has been disturbed in the recent past and it's possible fill dirt has been brought from somewhere else locally. At it's widest it is about 2.5", the thin cross section is about 1/4" and the tuber looking part is oval in shape , 3/4"x5/8". Thanks in advance for all your help.
