I’m trying to have SOME concern about this ...but honestly who cares about jewels from Napoleans era. Jewelry has never made any sense to me and I see no realistic value in it except to persons who obtain it for reasons beyond my comprehension. Shelter/food/clothing/plumbing/transportation/cleaning supplies/electricity/law/ and the most important is a relationship to God. Beyond these things jewelry is a burden of adornment and vanity.
Some people appreciate these things as works of art.
