I recently visited the fabulous rock, gem jewellery and mineral shop in Zeehan, west coast of Tasmania to possibly source some faceting rough. It can be found at 131A Main Street, Zeehan.
I highly recommend visiting the Zeehan Rock Shop if you are in the area, the knowledgeable proprietor, Richard, will be able to answer any of your questions regarding minerals and rocks in the West Coast area.
I left a couple of samples of my Gladstone smoky quartz faceting work in the glass cabinet at the front counter in the shop if you wish to see some examples close-up.
I travel to Zeehan about every second week for work, and have been doing so, on and off, for about 10 years now. In fact my association with Zeehan goes back to 1994 and earlier. I remember visiting Zeehan when I was a child – must have been back in 1980 or thereabouts, and buying some specimens as well as having a bit of a fossick. In 1994 I worked in Zeehan for a year with a large exploration company, using a room in the Heemskirk Hotel as an exploration geology office. I worked out in the field every day, it was quite an experience.
