I love my local jewelry store called Dan’s L&L Fine Jewlery http://danslandljewelry.com/.  They have new and used jewelry.  The selection is outstanding and bargains galore.  I just picked up this dragonfly brooch today.  It’s from the 1920’s and is sterling silver with garnets.  When I held it up to the light, I noticed the garnets are different colors. It has marcasite as well.  And it was a whopping $21!  The saleslady said it came from an estate sale.  I love vintage jewelry especially at these prices!
