I have a large cabinet sized specimen of uraninite from St. Terras Mine in Cornwall. Sat on the quartz matrix are two blue, presumably copper, minerals. Do any of you Cornish experts know what these two minerals are? One is a pale blue whilst the other is a much darker blue. There are no crystals because I broke a huge specimen in two and the blue patches were found in between the tightly packed quartz crystals. The very small amount of these minerals on the specimen has prevented me from being able to do a streak test so unfortunately I can't offer anything scientific that might help people identify the minerals........but if anybody has any ideas I'd be glad to hear them
Best wishes,
Alan
