clear quartz crystal, especially clusters
I keep them around my bedroom. I sometimes place them on top of decks. If you have a quartz CLUSTER, they don't need to be re energized like just individual pieces of quartz.
I am currently looking for a jet necklace or ring. If anyone knows of a good place to find one, please share. Obsidian and onyx seem easier to find at a decent price. Most of the jet I've seen is quite expensive.

here is a jet ring on Etsy.com. If you do a search under "all items" or under jewelry for "jet ring" or "jet necklace' you will come up with hundreds of items - some are real jet, some are just the word jet used to describe stone color - but there are authentic jet pieces in there.
