Is there a way to tell if the diamonds in my necklace are real?

You need a good laboratory with an international name, don't settle for less. From personal experience, I would only give you https://gemscience.net/services-and-reports/grading-reports/ as they do their job not one hundred percent, but one hundred and ten percent minimum. With them, you and your jewelry will be in good hands.
