TVGC meets at 7:30PM on the 2nd Thursday and 7pm on the 4th Thursday of the month at the Forest Grove Senior Center in Forest Grove, Oregon, west of Portland. See the address and map below, our calendar of activities for the next meeting or club event, and our category of events featuring our club events and meetings as well as area geology events, field trips, shows, and activities for our members and the general public.

Our meetings are open to the public and all are welcome.

If you would like to ask questions about membership, activities or events associated with the Tualatin Valley Gem Club, please use the form below.

If you are inquiring about Authentication or Appraisals of rocks, mineral specimens, or gemstone jewelry we are not equipped or have those resources to do so and do not have the connections for that. As far as identification of these we do have some members who might be familiar with more commonly found items and this easier to do when we are physically present at our meetings during our sharing time. Identification through pictures only can be difficult.

If you are a dealer inquiring about our rock show please do not use the contact below. Please refer to the page on this website labeled “annual rock show“, then look at the JPEG of the flyer where it will provide the email to use to contact the show dealer chair person directly. Please note that at this time we are currently full for the year 2022.
