Rough rutilated Quartz isn't really available on the market, given it's value as cutting rough. (the Chinese are buying it at the mine and shipping right to China). I found this chunk in an old collection from the 1960's - 1970's. The rough weighs 1,070 grams. The sphere, which basically matches it's overall color is from the Hawthorneden stock. It is far more impressive in person. The sphere weighs 265 grams. In direct sunlight these two are spectacular, the rutile inclusions cast rainbows, and demonstrate how dynamic good quality rutilated quartz can be.
