this Mikimoto Necklace of Graduated Pearls (you've managed to upload for Antique Jewelry Investors to see - thank you) in signature box, looks beautiful! MIKIMOTO Cultured AKOYA pearls are considered by many to be the Rolls Royce of pearls. Can you see the Mikimoto signature stamped on the clasp? It should be on the reverse of the clasp - M in a clamshell?
If you don't have a pearl gauge in your tool box :-) the diameter of pearls can be measured with a micrometer. Knowing the SIZE of the pearls will help the appraiser determine the value of the pearls. Because the pearls are graduated in size, you don't have to measure every single pearl. Simply measure the diameter of the largest pearl at the centre front and the smallest pearl on the strand near the clasp. Pearl sizes are expressed to the nearest 0.1 millimeter. Example: 7.5 to 7.5mm
If you can gauge the size/diameter of the pearls (see above paragraph) we will help sell by advertising your MIKIMOTO NECKLACE on Jewel of the Month on Antique Jewelry Investor (10% commission of the purchase price [when sold] - we will also do the appraisal at our own cost & it will be included with sale).
