I bought two quartz pendants from Mystic Wolf. One is fairly large that I use for workings, and I wanted another for wearing out on the street. I told MW what I wanted and in a few days I received the perfect pendant, exactly what I had asked for. MW cleanses their crystals prior to shipping. I had the distinct feeling that each crystal had been intuitively chosen for me. Mystic Wolf is a cut above the rest. I will absolutely buy many more gems from them.
If you are in the United States be aware that they ship via Royal Mail which is handed off to the USPS which is currently under attack. Mystic Wolf got my crystal to Chicago in two days. It sat in Chicago for a week before being finally delivered to me. If your shipping is a bit slow, don't blame MW. They ship promptly.
