Marble jewelry? Aah well, why not. We marbled everything else, so a little dainty jewelry piece was the only missing thing really.

What to do?
-get a piece of white polymer clay (Premo or Fimo are good brands) and mould until flexible.
-Add little speckles of black clay.
-Mould the clay until you like what you are seeing.
-Make the preferred shape.
-Make a hole with a needle big enough so your necklace or bracelet will fit (try to remove any big items from your jewelry, so it will go through the hole).
-let the necklace and clay cool down in the freezer for half an hour.
-Remove the necklace or bracelet carefully from the clay and bake the clay for 30 minutes (110°C / 230°F).
