My mother knows an artist who does these prisms. When my great grandmother passed away in December, my mother had these made. We gave the artist a few trinkets that reminded us of her and she made these prisms. I think they're great! We gave one to my granddad for his birthday and he really liked them as well!
Mine had a card (we liked to play cards), an amber earning (we went to the Museum of Natural History in NYC one year when they had an amber exhibit), a purple bracelet (her favorite color), a dolphin (we went to Sea World one summer), and a few other little pieces. The artist is local to Georgia, but the prisms are awesome!!! She has different sizes. This one is about 3" on each side.
