| Visiting the Bancroft Area? Some have asked us
where they can view our Custom Gemstones first hand. Stop in Lakeside Gems
on Hwy 28 south of Bancroft. To view Bancroft Rocks Gemstones currently available
at Lakeside Gems click here

 On this page are just some of the rocks, minerals and gems found in the Bancroft area. I'll be trying to collect them all. I'm also learning to cut (grind and or sand) them as I identify, collect and upload. A personal note to rockshounds, I would like to say that using books sold at the Chamber of Commerce, superior deductive reasoning and persistence, I went looking for ruby and purple sapphire, and found them. But the truth is, beginners luck is real. There are a lot of stones in this area. Perhaps if Canada had 12 sweltering months and about 8 times the population who were looking for gems, we would have more to offer than Brazil. It's just a matter of time until emeralds are found. I know for a fact that diamonds, ruby and sapphire found in Canada can be cut into world class stones. There are lots of known beryl deposits. |

If you see a mistake on this page please email me, explain what is incorrect, and what you feel it should it read. To judge scale, use the sodalite page, the rose quartz page or any page with a Canadian dollar coin in it. Note a euro coin and an american silver dollar are all about the same size. All the pics are directly proportional to the coin pages, if the pic is small that is only because the mineral sample is small. Simple right! Good. Well that's it. If you wish to know anything about the places I've been, ask me, I'm happy to help. One last thing, I got most of the pictures on the main pages from the kind folks at the Bancroft Chamber of Commerce Rocks and Minerals Museum, you cannot use them without their written consent. All of my polished stone pictures you can use, borrow or steal. If you notice a difference in the newer pictures, it's due to help received from Adrian Karley, Aberdeen, Scotland and the fine folks from news://sci.geo.geology on Usenet*. Perhaps the most functional group on Usenet. |
