My adopted 17 year old grandson uses my scrap ivory and makes letter openers and jewelery with it. This week end he set up at a crafts show and made $600. Last night he gave me the checks to deposit and one of them for $30 was made out to Vivian Knight. I asked him what the deal was and he said that it must of been from the old lady that bought the hair barrette . It seems when she was writing out the check he was explaining that the ivory was made blue by the mineral vivianite.
