Good Morning! They most likely are Akoya Pearls. Definitely the Murata Pearls. I believe they only worked with Akoyas. Do you have anything in writing? A box with the name Murata inside might help to give confidence to any would-be buyer. Selling pearls is not a black and white colour issue - how about the length? Most women know what length they have in mind when shopping for pearls. The PRINCESS Length is the most ppular. May Jewel of the Month we hosted a Persian Gulf pearl necklace and the common length sizes are written on this page.
