A Lake Superior agate is a beautiful gemstone that is found in the Great Lakes region, including on the shores of Lake Superior. This gemstone is composed of quartz, and its form is often made up of concentric bands of different colors that swirl around the gemstone. It is an igneous rock, which means it was formed as a result of cooling lava. It usually has a variety of colors including red, white, orange and black. Lake Superior agates are popular among rockhounds and people who enjoy collecting and appreciating rocks for their unique beauty.<\/p>\n

The Agate of Lake Superior is coveted for its interesting geological history and its vibrant colors. It began to form in the Precambrian Era over 1.5 billion years ago and was the result of volcanic activity. The hot magma rose and cooled, forming deposits of quartz or silica dioxide (SiO2). This eventually developed into Lake Superior Agate due to changes in temperature and pressure over millions of years. The swirls of color seen in the agate result from different trace minerals and\/or inclusions in the quartz.<\/p>\n

The Lake Superior agate gemstone is not only prized for its rare beauty, but it is also cherished as a symbol of home. People who grew up in the Great Lakes region and have fond memories of those places often cherish these stones as a reminder of their childhood. Furthermore, it is also associated with good luck. Many people carry small pieces of the agate in their pockets, believing that it will bring them success in whatever they set out to do.<\/p>\n

To authenticate Lake Superior agate, there are two main indicators to look for. The first is its overall texture, which can be quite coarse and even somewhat sharp. Secondly, the gemstone should have an array of color bands that swirl and mix, giving the agate its unique beauty. This is typically seen in fewer than 50% of Lake Superior agates. Agates that do not have this pattern are not considered authentic as they may have been dyed or treated to enhance their color.<\/p>\n
