Cubic zirconias are pronged and paved to the jewelry item to secure from loosing. Small stones are paved and held in place by little beads of the setting metal. Larger stones use a claw-shaped type of binding to be welded or soldered to the setting metal.
Brass Metal is much smoother and will protect your skin from rubbing. You will feel comfortable when wearing it. Also, jewelry made by brass metal has light weight.
