Psilomelane (WIP)
Bio
A laid-back and cool-headed guy. Psilomelane was the oldest gem of their generation and an overall pleasant person to be around. They're assumed to be on the moon but actually ended up stranded in the ocean. These days, they're too tired to do much of anything on account of being stuck in the darkness of the seafloor, but they have made friends with the sea life down there. They frequently wonder about the going-ons at the surface, they've been gone for a long time.
Appearance
Psilomelane is a gem of average build, thin and about 5 feet tall. They used to wear powder and a normal uniform with short white socks that have scalloped edges. Since getting lost in the ocean, all of their white powder has washed off and most of their clothes have either rotted off or gotten lost, save for some scraps of fabric here and there. They like to grow corals on their body.
Composition
Psilomelane is made mostly of a handful of types of manganese oxide. They have a large depression on their torso which was at one point filled with copper sulfate, but is now loosely packed with obsidian. One of their eyes was gouged out and has been replaced with a pink pearl. They're missing an arm, half of a foot and a finger on their remaining hand. One of their knees is broken and cannot bend.
Abilities
Because of their reckless experimentation in their youth with harmful chemicals, they're somewhat resistant to poisonous effects from copper compounds. Because of this, their body also doesn't accept replacement parts. Any prosthetics they receive remain sterile.

Background
Psilomelane was born a long long time ago, missing a good chunk of their chest. They spent much of their early years trying to find ways to fill it. They were also fascinated by toxic substances, so one thing led to another and they filled their chest-hole with copper sulfate that they grew themself. They thought it was really cool but after depleting the resin supply many times over the years, they were told to remove it and fill it with something less sensitive to water. Life went on rather normally for a long, long time.
Psilomelane was working patrol with their partner at the time who noticed a plume of smoke far on the horizon in the sea. The two knew that their island was the only landmass on the planet, but this sight contradicted that. Their partner snuck off into the sea and brought Psilomelane with them, and shortly into their expedition they were attacked by an enormous slug that ate Psilomelane and drove their partner running further into the sea. Before they could be digested they were spat out, because they tasted of the copper salts they used a long time ago, but they were left stranded at the bottom of the ocean.
thoughts on the others
Notes: Psilomelane was originally a disembodied head that their partner carried around all the time. The concept for their character has at one point been a pyrite, wavellite, paraiba tourmaline, hypersthene and gem silica before I settled on psilomelane for them.
