My wife found these and said "You have got to add them to the store!"  Perfect for wearing alone or adding to a dog tag.  

These Millefiori glass hearts are hand made and no two are alike.  Long, slender rods of colored glass are bundled together to make the design.  They are then heated in a kiln and fused together.  Each heart is then cut from the fused "log" while it is still warm and about the consistency of taffy and hand finished.

The red and white colors are opaque while the blue color is translucent.  Gorgeous is the only word that describes these hearts!
