Diamond stud earrings are a favorite for the holiday season, when shopping you should compare apples to apples, so many retail stores and websites say they have the BEST price, however do they really? You should compare color and clarity of the diamonds. You can buy diamond stud earrings for $99 but you are getting what you pay for. Many websites dont even bother to tell you what the color or clarity is - this is one of the first things you should review.
My past experience with Costco has made me more aware of all the specfic's of the diamond anatomy, if your going to spend money on a diamond - Get Educated.
