Amethyst (?) ring had changed color
I had an amethyst ring for years (which I wear from time to time). Now I've been wearing it for several months in a row, and today I suddenly noticed that the color had changed: the stone isn't lilac anymore but darker, and the violet tends toward grey. I bought it at a market, so it's possible that the stone isn't a real amethyst (even if I bought it directly from the artisan who made the ring), but the point is that it changed color without being exposed to any particular conditions.
I'm wondering if there's a meaning to it. Consider that today I felt an urge to clean my altar and restart my magic practice (I'm very inconsistent). Any ideas? Thank you in advance and sorry for any grammar error.
