Found!

I rushed through Cub Foods buying ingredients for an impromptu dinner party. When I returned to my car I found a white carton lying in the passengers seat, next to a pair of my reading glasses I had (purposefully) left behind. The package was a Clearwater Creek white shipping carton with this generic description:

84543
SKU#018085453 999
Abalone Organic Inlay BR
Color: Mul
Size:
Pictured above, the contents.

I had left the passenger side window open. I have had things removed from my car, but never placed in it. A gift by an admirer? Doubfull. - An abandoned 5 finger discount? Probably.

I rarely wear jewelry, but it might function as a good luck charm.
