Rainbow Quartz

"That was Rainbow Quartz. Pearl thought a fusion might give your video a little... something extra."

"Rainbow Quartz" is the fusion of Rose Quartz and Pearl. She made her first and only appearance so far in the episode "We Need to Talk".

Appearance
Rainbow Quartz has mauve-rose skin and voluminous platinum-blonde hair which appears to be a mix of Pearl and Rose's hair. It is long, large, and wavy like Rose's, while each tuft ends in a distinctive point like Pearl's. It is shaded with pale mint green and pastel pinkish-peach. However, this may be due to the effects of the pink and yellow spotlights. She possesses only a single pair of arms, and is slender and curvaceous with a tall stature, standing a head or two taller than Opal. Rainbow Quartz possesses two pairs of eyes; the top pair of eyes (Pearl) are larger and more rounded and colored a pale indigo, whereas the bottom pair (Rose) are thinner and more shapely with black pupils. Her nose is shapely and pointed like Pearl's nose, but short with discernible nostrils like Rose's. She also has defined lips that are similar to Rose's, although Rainbow Quartz's lips lack the sheen of Rose's.

Rainbow Quartz wears a sleeveless, skin-tight pinkish-peach strapless leotard with violet high-leggings. There is a stylized, four-pointed star, with the left and right sides of the star bent upwards, cut-out on the stomach area of the leotard where Rose's gemstone is. She also wears a loose, sheer, transparent long-sleeved, bright and pastel blue blouse with thin lime-green outlines over her upper body. Her outfit includes no footwear, but instead has long, magenta legwarmers that cover half of her lower legs and feet.

Abilities
Rainbow Quartz is assumed to possess standard Gem abilities and traits. Being a fusion of Pearl and Rose Quartz, it can be assumed that she is a strong warrior, like Rose, and agile, like Pearl.

She is very agile and graceful, as she can stand on the tips of her toes and execute acrobatics. Her weapon is yet to be seen, as she was only formed by Rose and Pearl for Greg Universe's music video. Given as Rose Quartz no longer exists, it is unknown if Rainbow Quartz will ever be seen again.

Trivia

 * Rainbow Quartz is the only fusion Gem in the series who has not said a word since her debut.
 * Rainbow Quartz, along with Sapphire and Stevonnie have yet to summon their weapons.
 * Her appearance bears a striking resemblance to the character Danse from the TV cartoon series, Jem and the Holograms.
 * Her outfit closely resembles an 80s-90s dancing/workout outfit.
 * Her skin, hair, and gemstones' colors are unknown due to the tinted lighting during her only screentime.
 * She was the first fusion on-screen to de-fuse of her own will. Other fusions have been damaged, broken, or have fallen out of sync.
 * Her formation was the first time Greg saw Gems fusing.
 * Rainbow Quartz is the first fusion revealed to involve Rose Quartz.
 * She is also the first fusion involving Pearl that does not have her dominant nose trait but is upturned and slightly pointy.
 * Her eyes seem to be expressing the different emotion of each of her parts towards Greg, a loving look from Rose's eyes and a cocky/boastful look from Pearl's.
 * Assuming that Steven and Pearl can fuse, Rainbow Quartz's design would differ from her debut.

Gemology
Iris Quartz/Metal-coated crystal
 * 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 interior spectral colors under some of the crystal faces from refraction due to brazil-law twinning in the crystalline structure.
 * 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 are 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.
