Background Information
Lake Superior Agates are smooth, colorful stones found along the shores of Lake Superior and are known for their unique shape, size and pattern. They are formed over thousands of years as water erosion takes away the softer sedimentary rock and leaves the harder, darker Agates behind. These stones are one of the Midwest’s most treasured gems and are highly sought after by collectors.
Identifying Agates
Identifying Lake Superior Agates is all about looking for certain characteristics and characteristics, such as shape and size. Most Agates are round or oval, with some having flat or convex faces. The size of an Agate usually ranges from 1 to 3 inches. They usually have a reddish-brown to black colour, with some having grey tones. Agates also feature striped or swirled bands and rings of colour, including shades of red, brown and yellow.
Testing Agates
To test to see if the stone is an authentic Agate, try the simple Moh’s scale. On the Moh’s scale, a 6–7 rating indicates a genuine Agate. Simply scratch the test surface of the Agate with a sharp-pointed object and if it leaves a powder on the stone, it may not be real. If it leaves an indentation, it is an Agate. To further test it, try using a set of diamond-tipped probes or a microscope.
Where To Find Agates
Agates can most often be found along the shorelines of Lake Superior, especially the northern shoreline near Michigan and Minnesota. The best place to look is in the shallow water near the shoreline. If you are looking for the more traditional Agates, try finding them among the cobblestones on the beach. Agates can also be found in gravel pits and along rivers and creeks near the lake.
Equipment Needed
When it comes to finding the precious Agates, you’ll need the right equipment. For starters, prepare by wearing a pair of waterproof boots to protect your feet and provide some stability while walking along the shoreline. Additionally, bring a small rake or trowel, bucket and flashlight to help spot the stones during low lights or in the evening.
Safety Tips
When looking for Agates in and around Lake Superior, please follow basic safety tips. Do not search for Agates in deep water; enclosed lakes and strong currents can be dangerous. Always pay attention to the water level and the shoreline, making sure that you always keep an eye on the waves and be prepared if the water level rises. It’s best to bring some sort of flotation device in case of an emergency. Make sure you check the weather before heading out and stick to fishing, swimming or any other activity while near the lake.
Cleaning Agates
Once you’ve found some beautiful Agates, it’s important to clean them properly. If your Agates are covered in mud, gently clean them in a bucket of warm water with a soft brush. For tougher dirt and grime, use a combination of mild dish soap and white vinegar. Afterwards, let them air dry or wipe them with a clean and soft cloth.
Cutting and Polishing Agates
After finding and cleaning Agates, you can decide to cut and polish the stones to make them shine. To do this, you will need a tumbling machine. The tumbling process can take up to a month to complete, depending on the desired result. Start by adding the Agates, water and abrasive materials (such as rocks and sand) to the machine and then turn it on. Carefully follow the manufacturer’s instructions and allow the stones to tumble until they reach the desired shine.
Valuing Agates
Valuing Lake Superior Agates can be difficult, as it depends on the stone’s size, shape, colour and pattern. Generally, the larger and more colourful the Agate is, the more valuable it will be. Some Agates can be extremely valuable if they have unique patterns or colours, so it’s worth having your Agates appraised by a specialist.
Gifting Agates
Agates are a popular gift and are often given to commemorate special occasions or to mark milestones. Agates are now available in a variety of shapes and sizes, and many come with a certificate of authenticity. If you’re looking to gift someone an Agate, consider a custom-made necklace or bracelet, made with genuine Lake Superior Agates.
Buying Agates
If you’d rather not go through the process of searching and finding the Agates, you can also buy them online or in stores. Be sure to do your research and investigate the seller before making a purchase. When buying online, make sure to read customer reviews and ask any questions you may have before making a purchase.
