The mounting of this brooch is unmarked but tested 14 karat gold--the pin stem and hinge are base metal. The micromosaic is in very fine condition--no scratches, chips, cracks, or fleabites :) The bright yellow roses provide an uncommon palette. The clasp is a simple C, also gold. The setting is a little loosey-goosey in its flip mechanism. It snugs up, but for the weight of the brooch, needs to be snuggled up to a garment to stay flat. It's in excellent condition ~ the hair compartment hasn't ever been used so is ready for anything.
