Appearance
Lake Superior Agates are naturally-occurring, colorful, semi-precious gems that are commonly found in the rocky beaches of Lake Superior in Michigan. It is believed that the agates had been there for thousands of years, due to the glacial erosion over time. The agates usually have a gray or brownish hue that can look silvery, which is why they are so highly sought after. However, as agates are composed of quartz, different colors ranging from a pinkish to a bright red, white or yellowish-green can be also found. The surface of the agate generally looks smooth, and it often has a banded pattern, making it even more precious.

Another interesting characteristic of agates is their ability to form layers, with bands of different colors. This can give the agate a striped, ripple-like appearance, making it even more valuable.
