How can you tell if diamond earrings are real?

To tell if diamond earrings are real, you can conduct some tests yourself. Try breathing on the gemstones to produce a fog and watch how quickly it disappears. Fake gemstones will hold onto the condensation for longer than authentic diamonds. You can also try dropping the earrings into water. Generally, authentic diamonds will sink due to their weight, but glass imitations are lighter and will float. If you remain uncertain as to whether your diamond jewelry is real, a certified appraiser can assist you. Shop a collection of diamond earrings on 1stDibs.
