Always Confirm Access and Collection Rules!

Before heading out to any of the locations on our list you need to confirm access requirements and collection rules for both public and private locations directly with the location.

The tools every gem hunter will need

When you're out looking for gems it's very important that you bring the right tools with you. You don't need a lot for most trips but there are a handful that are critical and will make your life a lot easier.

We get asked a lot about the equipment we use. Over the years we've found a handful of tools that we recommend to both new and experienced gem miners which we outline in great detail in our complete rockhounding equipment guide. These are quality options that also happen to be relatively inexpensive.

Below are the basic tools that make your life so much easier and save you a ton of time. Check out the full guide to see everything we recommend bringing. One quick note, as an Amazon Associate I earn from qualifying purchases but we try very hard to only recommend gear we would use ourselves and often recommend brands you can't find on Amazon.

At a minimum you should have:

1 - Sturdy rock hammer: The Estwing Rock Pick is our standard

2 - Rugged chisels: Try Kendo' 3-piece Chisel Set

3 - Compact shovel: The Koleiya 28-inch shovel works well

4 - Rock screen pan: The Wazakura Soil Sieve Set fits the bill

5 - Eye protection: DeWalt Safety Glasses are cheap and comfortable

6 - Head protection: Malta's Safety Helmet has been our go-to

7 - Jewelers lens with at least 20x magnification: Jarlink's Jewelers Loop is perfect

There are also a few books that have been extremely helpful in the search for gems. These books have great recommendations and tips:
