That piece of green coloured rock that you picked, looked like Malachite which can be fashioned into semi precious jewellery or carved display items and are believed to have Chakra balancing properties. Being a geology enthusiast, I am enthralled by your rock finding adventure in Xinjiang’s Gobi desert which is rich in many minerals like Yellow Jade, Malachite, Chalcedony, Carnelian and others, regardless of whether they are of gem quality or not. If only I could be there, I would be spending whole days searching and studying the rocks for their different stages of formation. My rock collection, whether found personally or bought, is taking up all the space in my display cabinet as well as my jewellery boxes. Really enjoyed this fascinating video of delicious food, rock search and smart answers. Thank you from my heart. ❤️
