I am in love with this black tourmaline pendant! It's not too tiny, it's nice & thick, but not that long. I wear it with a silver chain; it looks so elegant. So far, it hasn't tarnished, but I try to be extra careful with this kind of jewelry & store it carefully because it's susceptible to tarnishing. I avoid wearing it when it's very humid or if my hair is wet etc. This also seems more reasonable than some other crystal/stone pendants I've seen on Amazon. Overall, I'm very satisfied!
