Depends on the amount of gold used in the earrings and on the diamond’s 4 C's(it’s clarity, color, cut and carat weight). I would consult an experienced jeweler in regards to the value of your earrings.Also, you can ask your jeweler to appraise your earrings. It may cost you a little extra..but you’ll have a certificate of validation detailing the estimated value of your jewelry.
Good luck!
