Fabulous Vintage 925 Sterling Silver Blue Moonstone Filigree Poison Ring

This is an awesome vintage .925 sterling silver poison ring. It has a hinged lid topped with a bezel set moonstone cabochon - it has a milky white color with a vibrant blue glow inside. The hinge and clasp are very strong and unworn. On each side of the stone is scrolling filigree wire work. Finger size 10, marked 925 and also acid tested as silver. Really cool piece of history!
