This small and sweet nose stud is made of 14-karat gold. The bar has a length of 1/4" (6 mm) and has a stone on top. The stone has the shape of a drop, or a teardrop, held by a four-prong setting. On the opposite end of the bar, there's a small ball that keeps the stud in place. It's small enough to push it into the piercing but big enough to prevent it from slipping out. 

The stud is available in two different models. As you can see in the picture, you can choose between yellow gold or white gold. Both are 14-karat gold, which means that gold is mixed with other metals within the optimum measurement. For example, a bar at a gauge of 20g (0.8 mm) made of 24-karat gold wouldn't be an appropriate alloy.
