Oval dark blue and brown Nerikomi porcelain pendant

This is a handmade porcelain 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 1280 degrees. Diameter of the pendant is 1.5 x 0.7cm. The silver chain is 45 cm long. 

The necklace is waterproof. 

The design and color patterns are unique.
