Since turquoise is hard to come by every effort is taken to use every bit of it. This is one of the ways.
 
This is a man-made cabochon via taking turquoise chips and Bronze metal and compressing them under tremendous force to bond them together. This is followed by cutting out a shape and grounding it into a cabachon. Finishing it by polishing it with different grits of stone powder.
