I was going to say that it is flea bites. However, it is actually where the silver meets the glass, and I think it is just not a smooth finish/transition -- just rough area. Satin glass bottle; no stopper; has original sticker on bottom; neck, sides, and bottom of bottle have sterling silver; bottle outlined to look like a belt buckle and stirrup; sterling silver horse on one side of bottle; no chips or cracks (only defect is listed above); there is a small bubble inside the glass (below horse head) which can be seen in photos; from smoke free home; measures approximately 8.5" tall and 4 5/8" wide at base. I have not attempted to polish the silver. Nice collectible piece to add to your collection.I try to describe my items accurately, but sometimes I may miss something. I would be happy to send more photos or look at the piece and try to answer your question.
