I have always thought crystals and stones are beautiful. In the 80s I bought an amethyst cave as a present for my sister-in-law. I would have loved to have it myself. But I think my sister-in-law likes it too.
Amethyst is my month stone and I like purple a lot. I like lighter purple best, but darker amethysts are considered the finest, I've read.
Although crystals are very beautiful, I have not cared for their purported healing powers. It just hasn't been my thing. It's a bit like astrology. It's fun but I don't really believe it.
On the other hand, it doesn't hurt to read about crystals. If you also think it's beautiful jewelry, it doesn't matter if you also hope a little for its healing powers. After all, there is something that actually has a proven effect and that is the placebo effect.
So I wear my amethysts and hope it helps with my migraines. It can't get any worse than that anyway 😊.
