Rhodium is a noble metal with a whitish gray appearance, and it is typically applied to metal through electroplating. A plating of rhodium is applied over either sterling silver or alloys to give a piece of jewelry a bright, glossy and long-lasting finish.
Brushed is a process of using quartz sand to polish a chosen metal (gold, stainless steel, etc.) under high pressure. This finish is an effective method for removing surface imperfections. In addition, it gives a pattern of fine lines parallel to the brushing direction that creates a distinctive look for jewelry.
