Square green ceramic Nerikomi pendant on a silver chain

This is a handmade square shaped ceramic pendant made by myself from the scratch at my art studio. I applied Nerikomi technique and used natural oxides and pigments to achieve the effect. The pendant is burned twice under 1100 degrees. Diameter of the pendant is 1.3x1.4cm. The silver chain is 45 cm long. 

The necklace is waterproof. 

The design and color patterns are unique.
