Diamond studs never go out of style.  But, if you would like to add a very special sparkle to your diamond stud earrings, you can have a circular "jacket" made to surround each diamond with a circle of either pavé or smaller prong-set diamonds.  This will allow you to add even more impact to your beautiful stones on special occasions.  Another way to customize your diamond studs is to put them into a bezel setting that also has a circle of diamonds or other gemstones like sapphires or rubies.
