Nipple barbell with opals in flower ends

This nipple barbell is equipped with two identical flowers, one at each end of the 9/16" (14 mm) long bar. The bar is made of surgical steel and the flowers of rose gold-plated brass. In the center of the flower is a synthetic opal that is available in a variety of different colors, which is the only difference from one model to another. Everything else is identical in all the models. 

The flowers measure approximately 1/4" (7 mm) in diameter and the small opal about 5/32" (4 mm).

One of the ends is glued to the bar; otherwise, they won't face the same direction. To open it, grab both ends with each hand and turn counterclockwise. The non-glued end will unscrew. To close it, screw it back into the bar.
