This is a quartz crystal cluster that weighs 8.63 lbs and as you can see is a beautiful gem quality. There are 4 large perfect points in this cluster with one being a rare taby point. There is a small inclusion of what appears to be hematite as from the color and the location it came from would make that likely to be the mineral of the inclusion. The cheapest I found online of a simular quality but was only 6 lbs was going for $325.00. Google large clear quartz and you will soon see this is a great deal. The largest point stands 7.5 inches tall and is quite thick and clear. The one in the picture is the one you will receive.
