Kitchener-Waterloo Gem and Mineral Club
50 Years of Geological Fun and Education

KWGMC club logo The Kitchener-Waterloo Gem and Mineral Club was formed in 1965. For fifty years, our club has brought together people who have an interest in the lapidary arts and in collecting rocks, minerals, and fossils. Members are residents of Kitchener, Waterloo, Guelph, and other communities in Waterloo and Wellington Counties, Ontario.

The club meets on a monthly basis, usually at the Lions Arena, 20 Rittenhouse Road, Kitchener, Ontario. Meetings include speakers, workshops and the ever-popular monthly raffle for gems and minerals. Special events include picnics, pot-luck suppers and field trips.

The club also provides a forum for an exchange of information and ideas about the hobby. We also promote safe and responsible collecting, and we work with other federation clubs to secure more collecting areas.

Our club is a member of the Central Canadian Federation of Mineralogical Societies (CCFMS).

Kids Club

The Pebble Pups is a kids club created by the KW Gem & Mineral Club aimed at younger kids, aged 7 to 12 years old. We meet the first Saturday of every month between September and June, usually at The Rock Spa (396 Victoria Street North, Kitchener, Ontario) from 10:15 AM to 11:15 AM.

The Pebble Pups program is packed with games, hands-on activities, and speaker presentations that get the young kids thinking and inspired about the earth sciences. Over the years that the Pebble Pups program has been operating we have averaged approximately six to nine kids per month. On several occasions the Pebble Pups had a high of sixteen kids at one time! We try to entertain and educate the Pebble Pups through numerous activities, and thus far I think my favourite activity to do with the kids (and one that they get most excited about) is playing ROCKO! The other activity that we get a high turnout for is when the kids make their own mineral box to store personal collections.

The Pebble Pups is always looking for in-kind donations in the form of rocks, minerals, fossils, games, and/or books related to the earth science field. The kids are captivated by actually holding a physical specimen in their hands and especially one that they could take home to keep. The more colorful and unique looking the better! The Pebble Pups is always open for KW members to solicit new members. It is very exciting when we get an e-mail or phone inquiry regarding the Pebble Pups because we know that the 'word' is out on the street and more kids are curious to find out about it. It is definitely worthwhile getting e-mails from parents, whose children have moved on from the Pebble Pups due to age limits, that say that their child(ren) had a blast and will cherish their time with the Pebble Pups!

For more information about the kids' club, contact Robert Maric.
