Sajen Signed 925 Sterling Silver Stone Pin Brooch Pendant

Sajen signed 925 sterling silver stone pin brooch. I do not have a gem tester or rock identifier so I'm not sure what the stone is but it is stunning! Possibly a type of jasper??? The stone is bezel set and surrounded by a scroll design in sterling silver. This is a brooch but also has a loop for hanging as a pendant. I have not cleaned this. Pre-owned in very good condition. Clasp works fine.
