lk salon 0.3 carat Necklace Pink Gold Lab Grown Diamond Air Lab I am selling this because I received a similar design as a gift. Regarding minor scratches that occur with normal use, please understand that this is a used item before purchasing. It is a slide chain, so the length can be adjusted. lk salon does not provide a certificate of authenticity for 0.3 carat diamonds, so there is no certificate. To prevent replacement, returns are not accepted. If you were looking for this, how about this affordable price? Thank you very much. Accessories...Box
