Diamond's may be a girl's best friend, but they're also the sparkling birthstone for those April babies out there. Found in beauty items for their shimmering qualities and/or exfoliating properties, diamonds don't have to be expensive to look good. Check out my widget below for some beauty products that include this precious gemstone as an ingredient. Some are decadent — we're talking diamonds, after all — and some are easier on the budget, so you can drip in ice without the guilt. Also, be sure to check out my beauty posts for Aries and Taurus, the astrological signs for those of you born in the month of April.
