Hi every one I trust that this text finds every one well? and hi to Michael. I would sergeant that you should seek an archaeologist at your nearest University as most of them materials look as if they had bin carved at some point. there are three that perplex me! the first is the ones that looks like a tooth it looks like some one went threw a lot of trouble to curve the materials in just the wright places to get that look on a layerd matrix. there are geologists that could help detect if the minerals where hand shaped or if the shapes are naturally formed!, but to me it differently looks more tampered with than natural. The one that looks like and Avocado with a spiral seed centre that is deferentially not natural! on the curved lines of a rock, they are to perfect and the ceurvicure is not that of natural materials there is no signs of natural erosion that could cause lines like that and so perfectly uniform on that mineral, that means that it has bin removed by some methodology of manmade tooling I am sure. also the fact that there was a half carved garnet defernetlly hints at personalisation findings as garnet was well used and prized for many of that period, for both mythological beliefs such as protection in battle warding off bad wishes from others and status symbology. Royalty would never have been seen without garnet as it was a massive power symbol of Roman and early civilisations talismanic uses.
Best of luck and pleas keep us updated on what happens but I am pretty sure that it is a fine of some sought.
Best regards Jarryed.
