This is an absolutely beautiful Sherman brooch - signed with the oval plaque, which makes it an earlier creation.  It measures 2 1/2" x 1 1/2" and is extremely glitzy.  There are two oval cabochons that have an incredible color-changing aurora borealis coating.  There are a combination of faceted navettes and non-faceted (smooth) navettes surrounded by beautiful fire-filled rhinestones.  The smooth stones may be replacement stones, I'm not sure - they certainly do seem to share the same coating.  There is minor wear to the AB coating on the cabochon.  My price reflects the condition of this piece; however, it is still an awesome Sherman creation.
