Hi, my partner and I came across these, ??, don't know what they are, they weigh around 10kg, we originally bought them off a stack of quartz Crystal rocks, we bought 3, my girl is into crystals and their healing properties. They are quite bizarre, never seen anything like them and was hoping some one here knows, 1.what they are, 2.are they real or just rocks that look like animals, one looks so much like a dog. I'll let you all decide.
