your pearls sound beautiful. These pearls you were given on your 16th birthday clearly mean so much to you. If you decide to hand your Pearls down to your granddaughter, I'm sure she will treasure them, as you have over the years.
Majorica pearls are REAL man-made pearls Carol. There is a general confusion with the term "REAL PEARLS".
Fine quality Natural Pearls are very rare and very expensive & usually pass hands privately.
Of all the Imitation pearls, Majorica Pearls are my favorites. Majorica have perfected the art of manufacturing a perfectly round pearl. The production of Majorica Pearls also pose no threat to marine environments, as no pearl farming is involved in making Majorica Pearls.
There are so many factors that influence the value of Pearl Jewelry and in reference to your Majorca pearls. The Condition of the Pearls, whatever type of pearls, is one of the most important.
After worrying about the market value, sometimes for decades, most women find it a relief to finally know what their jewelry is actually worth in financial terms. "own their jewellery."
