The two other items are clear quartz crystals. The left has small stones to represent the chakras. This is a very strong crystal, I have cleared it during the last full moon, but have not used it yet. I'm waiting for my next healing session to use it, and I'm very excited about it.
On the right is all "diamond" quartz crystals in a vertical cylinder. It's a strong, but gentle energy I feel from it. I've already worn it several times after cleaning it with a full moon. I really jive well with its energy and I'm very happy I bought it. Overall I love my purchases and they add well to my collections of stones and crystals. I'm very happy with it all.
