I have a pair of earings that I was wondering if they are real diamonds and also what the stamp on them mean. They look like they might be 1/2CT in size and white gold diamonds. They are round in shape and only have 3 prongs not the typical 4 prongs.

How to Test a Diamond | Tell a Real Diamond (http://www.livescience.com/29172-how-to-test-a-diamond.html) The link provides ways to test the diamonds at home. Your best bet though, is to take it to a jeweler to get an appraisal.
