Afghanite is a rare mineral that was first discovered in Afghanistan in the early 1960s. It is known for its stunning deep blue color, which is reminiscent of the sea. The gemstone is also found in shades of blue-green, green, and gray. However, the sea blue variety is the most sought after due to its rich, mesmerizing color.

What sets Afghanite apart from other gemstones is its unique chemical composition. It is made up of sodium, calcium, aluminum, silicon, sulfur, and oxygen. This combination creates a mineral that is both rare and beautiful. Afghanite is found in igneous rocks, which are formed from cooled and solidified lava or magma. This makes it an incredibly valuable gemstone, as it is not only rare but also difficult to mine.
