Light Blue Trio
The Trio Piercing by Anatometal with its three Swarovski zirconia in an 18-carat yellow gold setting manages to make piercing areas sparkle that don't have much space. With a diameter of 3.5mm you can wear this attachment almost anywhere and still have a fancy piece of jewelry. And if you like it a bit bigger, you can take the 4.5mm diameter variant.
In this version, all three zirconias sparkle in a light blue. Attention: the color is less gray and more light blue than in the photos!
The barely visible setting of this piece of jewelery ensures that the Swarovski rhinestones can sparkle. 

Backside
These ends screw on, and work only with internally threaded ends of the same gauge. Threaded ends and posts are sold as individual pieces. If you’re looking for a complete piece of jewelry, make sure to purchase a corresponding threaded post for your end.
