We don't ask for feedback as does eBay, since that's an imposition on our customers, but occasionally we get comments anyway. We don't use a customer's name without permission.

I just finished checking the rocks in.  I could not have asked for anything more! Truly, you have been the best vendor I have ever worked with!! Thank you so very much for packing the rocks the way that you do so that it was easy for me to differentiate each type of rock and for including the description of each so that all of our students and instructors have access to information on each of the rocks you collected. I am very impressed; all the way around! You have thought of everything! We can't wait to order from you again when it is time.  Brandy White, Clovis Community College

I feel compelled to make a few comments on your operation, in short, it is one of the best I have seen in my 84 years.  Your descriptive labels are excellent and certainly up-to-date with current thinking.  Your packaging is first class.  Your specimens are excellent, large, clean and about as close to textbook examples as one can get.  Lastly, your prices are ultra-reasonable!

It’s been a real pleasure to shop with you! Thank you for your excellent service.
Your specimens are beautiful! I really appreciate your inclusion of the geological history of the rocks and minerals you’ve collected. Knowing where each specimen was found is very important to me and your inclusion of that information is very much appreciated!
On top of that you are clearly taking great care to send the rocks and minerals safely and quickly.
As a future Earth science teacher, I’d say you definitely get an A, and set the curve for the rest of the class!

“Geological Specimen Supply were a pleasure to work with. Very fast and clear communication. I ordered a variety of samples to a university in Canada for teaching labs, and they were very helpful in providing the most affordable and secure delivery available. Everything was packaged very carefully and I could not be happier with the quality of specimens provided. Definitely doing business with GSS again in the future!”

From a teacher April 6, 2024: " I want to say thank you so much for always offering such great samples at such great prices. I ordered some for one of our classes during the pandemic and all of the extra information and thoughtful study sets were so appreciated! I still tell every class something I learned on one of the cards: sulfur is the only mineral you can hear :) Thanks again!"

October 2, 2024 - we like the sentiments here and agree with the kids!

I wanted to let you know that all 3 boxes of my order arrived, thank you! My post office was somehow confused, I think it was just because the boxes were heavy, ha! So stoked with the specimen quality and your packaging was impeccable. I was asked appropriately 1,000 questions by my 7 and 8 year old daughters while unpacking and I finally said, "Hey, can you stop asking me questions!?" and my 7 year old said, "But Mom, you said scientists should *always* ask questions." 😊
