Opal is a gem fusion between Amethyst and Pearl. Opal has a lean, toned body with two pairs of slender arms. She is very tall, being at least twice as tall as Garnet. Her height is partly due to her constantly standing on the tip of her toes. Opal has periwinkle skin, a thin, rounded face with a pointed nose and plump lips, baby blue eyes with dark blue pupils, and thick, wavy, off-white hair. Her hair extends slightly past her calves, tied back into a rowdy ponytail by a pale salmon band. Extending from off the ponytail's sides are chin-length bangs resembling Pearl's and two small pigtails in the front tied by pale yellow ties. Her two gemstones are located on her fore head and her chest. Opal's outfit consists of fuchsia, knee-length leggings with pale-violet cuffs rolled up, and yellow flat boots. Amethyst's ability to live in the moment and Pearl's obsessive single-mindedness results in a stable fusion. Opal achieves a sense of peace in that balance that Amethyst and Pearl rarely experience on their own. Opal's personality is theorized to be a combination of Amethyst's carefree personality and power, along with Pearl's grace and precision. She is the smallest of the three fusions

Sugilite is a gem fusion between Amethyst and Garnet - Garnet herself is a fusion between Ruby and Sapphire Sugilite is a colossal and menacing fusion with a stocky, bulky build and four arms (each pair seeming to share a shoulder joint), with black markings on them. She features four, medium-lilac eyes located under a strong brow and a fifth one above it. She wears pointy shades covering her bottom four eyes. Her mouth is twisted into a grin and filled with sharp, pointed teeth. She has a giant plume of spiky, dark purple-black hair kept in an untamed style similar to Amethyst's, but messier. Her skin color is lavender, like Amethyst's. In close-ups of her, she appears to have purple fingernails painted to appear as gemstones themselves. Her gemstones are located on her chest, and on the palms of the hands of her arms. Sugilite cares for herself first and foremost. Though she carries out mission objectives effectively, she has problems with impulse control and does not hesitate to use her power for personal gain. She combines Garnet's headstrong, unwavering nature with Amethyst's indulgence, as well as her negative attitude towards authority. The resulting personality is a volatile mix that is highly aggressive and dangerous to everyone she encounters. She also appears to be cold like Sapphire can be, containing Ruby's anger issues and Amethyst's recklessness. All of Sugilite's constituent Gems contribute to her general temperament, though the similarity in the nature of Amethyst and Ruby seemingly overwhelm Sapphire. Though much like Sapphire, Sugilite refuses to change her mind when it's set on something, like not wanting to defuse. Sugilite likes to show off She is the largest of the three fusions
