Anne Elliott's photos with the keyword: trigonal crystal system

The largest of these tiny crystals is maybe half an inch tall - can't for the life of me remember if they are Quartz crystals or something else. I think they came from one of the mines in India, many years ago. Feels a little strange to be posting this kind of crystal at this time of the year - normally, I would be posting ice crystals from an overnight frost! Not as sharp as I wanted, but it was a heavily overcast day yesterday (with a weather advisory in effect), and there was absolutely no light in my place.

Well, not exactly, but that is what this image makes me think of : ) Should have saved this photo of tiny (maybe half inch tall) Quartz crystals to post on a day with heavy snow and bitterly cold temperatures. Not too organized at the moment! If you are living in a world of white with frigid temps at the moment, hope this colour warms you up.
