Genuine Pearl Necklace Measurements by an amateur: Diameter of each pearl: approximately 6.5-7mm Length: approximately 46cm (from end to end of the pearls) Weight of the necklace including the clasp: 37.1g Number of pearls: 64 ☆ I looked, but there are no markings on the clasp. I don't have an appraisal certificate either, so I'm offering it at a low price. Although there is no case, I will carefully wrap it, and package it with cushioning material, then ship it in simple packaging. It's been a while, but it's a beautiful genuine pearl necklace. The necklace string is not loose, but it might be a good idea to have the string replaced at a jewelry shop before using it. It has been stored in a drawer for a long time. I'm selling it to organize my collection, as I have other pearls of different sizes. It feels heavy. Perfect for formal occasions, graduations, and entrance ceremonies. The size of the pearls is not too large or flashy, making it easy to wear. I have already lowered the price. I cannot offer any further discounts. Please refrain from negotiating. ☆ To prevent switching, returns and exchanges are not accepted.
