30 Day Clothing and Accessories Challenge Day 8

Your most expensive piece of clothing.  Again, I'm cheating, since technically this is jewelry, not clothing.  I usually don't buy expensive clothing, since I know that garments made to last (wool, silk, etc) won't get much use here on the sunny coast, and that lightweight fabrics are more easily harmed.  My mom gave this gold butterfly necklace to me a long time ago, and even I have no idea how much it cost.  It must be pretty expensive though!
