My mother in law gave me these pearls and I'm very curious about them. She inherited them from her mother who was a world traveler. At first glance, I thought they were imitation and just fun costume jewelry. But then I did the tooth test and sure enough, they feel gritty. They are also heavy and no two are the same. I've searched all over the internet but can't get any clear answer on what they are or their potential value.
