This is a French art glass perfume lay down perfume bottle with a metal stopper (brass or bronze). The date is circa 1860 during the Grand Tour.
The bottle is a chatelaine with a chain that young ladies used to hang the bottle around their neck, or from a purse, or perhaps a belt.
The entire scent bottle, from the top to the end of the metal stopper is 6 ¼" long and the bottle is about 1 ¼" wide.
The glass has at least two layers as you can see the tip is clear glass and the bottom layer is cranberry red or pale ruby.
The metal top is hinged to the mount fitting. There is a tiny clear glass insert to keep the perfume or cologne from spilling out.
The top of the bottle has hand enameled flowers in blue with green leaves, and gold paint accents.
There are no chips, nicks or cracks. There are quite a few air bubbles in the glass due to how the glass was created back then. There is a little bit of perfume residue inside the glass at the tip.
