It looks like more and more girls are no longer BFF with diamonds. Instead, many brides are opting to wear their favorite gemstone on their left hand to symbolize their pending nuptials. Although  the rings may have a few diamond accents for added sparkle, the center stone will be anything from amethyst to ruby to sapphire-even pink topaz and pearls. This colorful break with tradition is sure to stand the test of time. Who says diamonds are forever?
