Many years ago my husband bought me some Tiff pearls and they were beautiful, silverly, and looked like they had ball bearings in them with a mirror finish, but I made him return as I already had my mom's 18" pearls. Now I would like some 16 pearls and we went looking. We looked at M, Tiff and Blue Nile in person at our local luxury mall as I wanted to see the sizes of pearls and necklaces. All inventory was low and we were told about a pearl shortage. The Ms were in a set where the earrings were silver and the necklace was creamy and 18 inch. At Tiff, they only had 2 18 necklaces, one creamy and both had shockingly mismatched sized pearls on the strands. The Blue Nile was too long at 18, pearl was too big at 8, but was clearly the nicest necklace we saw. The color was white parls with a silver look, but no ball bearing look. Am I wrong to want that? Also, Im not sure if what I am looking for is white pearl with a silver cast or what the silver akoya color is on websites. Thanks in advance.
