Vintage Silver Earrings - Large Reticulated Hoops (Pierced)

These are supposed to be from the days when Silpada was a home party business (MLM), but I cannot find a hallmark on the earrings. Marked or not, the earrings are beautiful sterling silver, but unfortunately a little heavy for my taste, so I never wear them. They will be shipped in the existing packaging.... which may or may not be original to this pair. Not counting the post and bar (for pierced ears), the actual hoop itself measures slightly over one inch.
