Customer Reviews
Nice sapphire rough
Got some sapphire rough from here last week. It looked pretty good, exactly as pictured online. The shipping was quick, got to me in California in about 4 days. Easy to order, no fuss. Definitely a good experience overall.
Good quality as usual
I ordered a lapidary saw from Northern Gem Supply, and it was just what I expected. This isn't my first purchase, and they consistently deliver good stuff. It took about a week to get here, which is standard for them.
Smooth order for agate slices
I recently ordered several agate slices and a rock tumbler kit from Northern Gem Supply. The website was easy to navigate, and the checkout process was straightforward. My order shipped out the next day and arrived in five business days, which felt reasonable for a standard delivery. The agate slices were well-packaged, and each piece looked unique with nice banding, matching their online descriptions pretty closely. The rock tumbler kit included all the listed components, and the instructions were clear enough to get started without any issues. I had a quick question about tracking, so I used their online chat support, and the response was prompt and helpful. Overall, a solid experience; everything arrived as expected and in good condition, making for a reliable purchase.
Fantastic ruby specimens!
I just received my ruby specimens and they are absolutely gorgeous! The color is so vibrant, even better than the photos. Shipping was super fast, got them in like 3 days, I was so surprised. I'm already planning my next order, probably some more fluorite octahedrons. Love this store, seriously can't wait to see what else I can find!

Do those 'new customer' discounts usually apply to everything, even if something's already on sale?
Are the geodes from here actual genuine amethyst or some kind of treated stuff? Seen some fakes online lately.
Anyone ordered from both Northern Gem Supply and say, The Rock Shed? Wondering which one's better for tools like lapidary saws.
How are returns here? Got a sapphire rough that looks a bit different than I expected. Is it a pain?
Hey, thinking of grabbing one of those rock tumbler kits. Anyone know if they ship to like, Kansas City pretty quick?
