This gemstone necklace reminds me of Paris. The stones bring back memories of the paintings in the Louvre, Paris Markets full of antiques & curiosities, fresh fruit pastries in the bakery windows, fashion on the streets, and sipping on a Kir Royale (champagne & creme de cassis) and watching people stroll by on the cobblestone streets. 
Beaded section is 15.5” but you can make it as long as 18.5”
