Hand carved rainbow onyx goblet. The beautiful polished surface of natural stoneware will stay shiny if used to serve dry items as acid in liquids will dull the surface over time. It is safe to drink wine out of these goblets, but you will see the inside of the goblet dull over time. We recommend cleaning with a damp cloth. No microwave ovens, dishwashers, or chemical detergents please!
Approximate size 8 x 5 cm
Onyx is created from the cold water deposition of calcium carbonate, and varies in banding and colour. Rainbow onyx is a form of agate and forms mostly in cavities of eruptive rock or lava. The banded structure, with successive layers, displays a variety of colours.
