The Opal Virtue
Yellow gold and white opals - a match made in heaven. The 2mm synthetic opal is framed by filigree gold threads made of 18 carat yellow gold and has a diameter of 5mm. This means that this attachment from the company Anatometal not only fits well into your ear piercing, but also looks very nice in a Medusa piercing.

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.
