Sapphire 1.5ct Silver 925 18k Gold Finish Necklace, Unique Design (Based on Reference Material) I haven't used this in a long time and have been storing it. I received it from my grandmother. I don't know the details. Due to long-term storage, Some parts of the metal have blackening or dullness. Since there is no appraisal certificate, Please refer to the last photo, which is a screen showing information about the stone and metal, by searching for the same product online (as it has a rare design, it is believed to be the same). *Please note that this is not an appraisal of this product. *The product name is also quoted from this source.
