My favorite mineral is rose quartz. I have a piece of rose quartz (I don't even know how I got this one, maybe someone gifted it to my parents and I just found it at home, I don't remember) and I just feel so good holding it. I know it's not traditionally a stone that is used for grounding, but I always feel very grounded and "cocooned" when holding it. It also helps me concentrate and calms me down. I always feel more capable to deel with life when I meditate on that piece of rose quatz. It's just a really good fit for me.
