How to tell if a diamond necklace is real?

If you're not sure if your diamond necklace is real, there are a few things you can look for. First, check to see if the necklace is made of solid gold or silver. If it's plated with another metal, it's likely not real. Also, examine the diamonds closely. Real diamonds will be well-cut and have sharp edges. Finally, hold the necklace up to the light and look for flaws or inclusions in the stones. If you don't see any, chances are good that your necklace is real.
