Vintage Swarovski stones in a wonderful Aquamarine blue color.  I've set them in open-backed settings to let the light shine through for a more subtle sparkle.

Stone Size: 14x10mm / 1/2 inch / 1.4cm each
Stone Material: Vintage Swarovski Stones, Aquamarine
Settings: Heavy cast Brass with your choice of plating (Antique Silver plate shown), offset loops to prevent the settings from flipping around and showing the back. 
Length: 16" (40.6cm) with a 2" extender chain for flexible sizing

May be ordered with matching dangle earrings.
