Quartz, Greely, Ontario
The occurrence at Greely was very active years ago but I have not heard of any new specimens being produced for many years now. It is a "Herkimer-Diamond-like" occurrence where quartz crystals occur in limestone. The quartz crystals are very interesting in that they are often hoppered with clay inclusions and have many interesting vicinal growth features on the crystal faces. These quartz crystals can be colourless but more often have a smokey colouration. Sometimes they show prominent phantoms. Here are some very nice examples!
