Antique Miniature Venetian Adventurine Chatelaine Style Perfume Scent Bottle.  This is a very nice antique 19th C. Venetian glass scent bottle.  It has swirls of aventurine on a black body and applied blue top.  It is in excellent condition with no chips or cracks.  It measures 1 3/8" x 7/8" and about 3/8" thick.  This is from my personal collection, I have had it for about 25 years.
