Textured silver pendant with peridot and opal

This is a unique pendant made from textured silver using a technique called 'reticulation' whereby the silver is heated to a high temperature (3-4 times) and cooled causing the surface to bubble, creating a one-off patterned effect. 

It is quite large, measuring 3.5 x 2.5 cm and is set with a small 3mm peridot gemstone and two 3mm opals to complement the silver. It is presented on a 45cm (18 inch) sterling silver chain.
