I really don't know anything about stones and crystals, but I'm open to the idea that they have different energetic properties. I mean, they use crystal quartz in wristwatches and other mechanisms, right? Piezoelectricity.
I've always liked making jewelry with semi-precious stones, and I'm drawn to some more than others. For example, I love carnelian. My favorite precious stone by far is sapphire. Maybe it has psychological associations I'm not conscious of. Maybe there's something energetic going on.
I'm glad you feel drawn to studying stones, and I hope you'll share anything you learn that you think might be useful for us.
