Rainbow Quartz has an appearance similar to that of other Rainbow Quartzes, as they have a slim but curvy body with two arms and legs. They have peach-pink skin, short and messy brown (formerly blond) hair with pink highlights, and three eyes; two black eyes with brown bushy eyebrows, and a light blue eye underneath their right one. Their gemstones are on their forehead and navel, now colored pink and other pastel colors.
They wear an off-shoulder version of Steven’s shirt on top of Pearl’s top, leaving their midriff and navel gemstone bare. Pearl's sash pokes out from Steven's pants, now shorts, and they also wear Pearl’s socks and flats.
The term "rainbow quartz" can refer to two different types of gemstones:
Iris quartz, sometimes also marketed under the name "rainbow Quartz" or "anandalite", is a quartz crystal displaying internal spectral colors under some of the crystal faces.
Metal-coated quartz, which is artificial, has a metallic rainbow coloration on the surface, and is created by applying a microscopic layer of metal (typically titanium) to a heated quartz crystal via vapor deposition.
Rainbow quartz is associated with hope and optimism.
Quartz gemstones are very durable and hard.
Rainbow quartz is not a traditional birthstone.
Angel aura quartz is actually the technical name for rainbow quartz.
