What is the state gemstone of Alaska?

The state gemstone of Alaska is jade, which reflects the significance of this unique stone in Alaskan culture and its geological presence in the state. Jade is a highly valued gemstone, particularly in indigenous cultures, where it has been used for tools, ornaments, and other artifacts for thousands of years. The presence of jade in Alaska's geology also highlights the natural resources found within the state, which are significant both economically and culturally.

In contrast, the other gemstones listed do not hold the same official designation or cultural significance in Alaska. Amber, for example, while a beautiful stone, is more commonly associated with areas outside of Alaska. Onyx, primarily found in other parts of the world, does not carry the cultural weight in Alaska as jade does. Granite, while important in geology and the formation of many landscapes, is not classified as a gemstone. Therefore, jade stands out as the state gemstone due to its cultural importance and natural occurrence within Alaska.
