Looking for a beautiful gift to give..... Any suggestions

My MOH has been the best! She has been by my side and is basically doing all of the planning. She is also doing my hair and all of my bridesmaids and flower girls hair for the wedding for free. I have 6 other bridesmaids and two flowergirls. I want to show my appreciation by buying her something special. Funds are low right now because the wedding is next week. And I need to buy it before the rehersal dinner next Fri. What can I get for her that will show my token of appreciation without going broke? What are you brides getting for your maid of honor? Thanks so much in advance Diva11236
