Not only can convertible jewelry be worn during work of after hours by attaching or removing the colored stone; the fact that a single gemstone can be enjoyed as two different pieces of jewelry, such as a brooch and pendant, is also a strong point. Since the gemstones are repeatedly attached and removed, it is important that the connecting mechanism be both strong and easy to use. Looking at this area from behind, near the top we can see a box and safely that hold the tongue in place. The head slides smoothly into place, and the safety fits securely. The pin is constructed to hold the safety closed, so there is no chance that safety will open while the brooch is being worn, allowing the gemstone to fall. When choosing gemstones, it is also necessary to consider the effects of warm-and cool-colored gemstones and the precious metal in the setting/ for example, platinum looks better with blue gemstones, while yellow gold matches the warm reds and orange colors. However, the point is that this piece allows you to use the gemstones freely and to enjoy switching the heads.

The best thickness of pin for this brooch is one millimeter. A pin of this thickness will have an effect on fabrics, but anything thinner will be unstable and bend easily, making it difficult to deal with. In addition, the pin latch is constructed to hold the pin securely in place when closed. It clicks shut audibly when securing the pin, so there is no chance that the brooch will come off unnoticed.
