Credit goes to whomever first named this design, but the Cha Cha is just a fun, light-hearted style that each jewelry maker interprets in his/her own way. My Cha Cha usually consists of tiny beads - 4mm or 5mm (6mm feels a little big for my design taste). They typically drop from a stainless steel ear wire to about 2". I price these at $25/pair. If you have a favorite gemstone bead, just specify; or tell me the color you would like and I'll recommend.
