Hi all! I am getting married at a vineyard in Sonoma in September. My bridesmaids are all choosing their own dress style, but the color is Mahogany by Alfred Angelo. The groomsmen are wearing grey Vera Wang vests/pants, white shirt and mahogany tie. I plan to purchase the jewelry as part of their bridesmaid gift but have been struggling...what color/type of jewelry would be best? Silver? Pearls? Rhinestones? Thanks!
