Sterling Silver pendant magically holding a volcanic cube.
Stone size : approx 15*15 mm.
Chain : 2 mm width Sterling Silver curb chain.
Solid Silver pendant & chain.
The lava comes from deep Earth and can hold fire, so I can solder a Silver pole through the Lava and make this magical pendant.
Natural gem.
