Ruby, The Little Acerola.

Ruby lives at Mask Island with the other gems, and she considers Jade and Moonstone her parents, although the real mother figure is Tiffany Stone, the fusion of both gems.

When she emerged, was quickly discounted for being one eye blind, poofed a few hours after emerge. One day, she was assigned to a mission due the lack of soldiers avaible, to retrieve a gem artifact in a small planet. Her ship was stolen by Jade, Moonstone and Carrollite, and they became friends.

She has a weapon, but she never really wanted to learn how to summon it and how to fight. Her only power is a protective bubble.

Flowers in her hair are just like Garnet's glasses, she can summon at any time, and that will reflect on her fusions.

Ruby never fused, she is to shy to share her own light with someone.

~Guess who finally got a watermark?~

This is Carrollite. She used to menage Bismuths back at Homeworld, but now all she manages is a little Ruby at Earth.

She helped Moonstone to build the temple and the new warp pad at the Mask Island. Carrollite had an affair with the other gem, but they stopped in respect to Jade.

Her personality is, in a comic way, a fusion of Peridot, Eyeball Ruby, Aquamarine and Dolores Umbridge (Harry Potter).

Her powers consist of a very developed ferrokinesis, and her visor can show all the imperfections on a building.

the cobalt series, part one: the geology

cobalt in the zambian copperbelt occurs primarily in three mineral forms.

carrollite — copper cobalt sulphide, CuCo₂S₄ — the most economically significant cobalt mineral in the zambian ore system. named after american mineralogist james carroll booth who first described it in the 1850s. it forms in the same reducing chemical environment as the copper sulphides — chalcopyrite, bornite, chalcocite — and is intimately intergrown with them in the katangan basin sedimentary sequences. where copper concentrates, carrollite concentrates alongside it. they are, in a geological sense, inseparable companions.

cobaltiferous pyrite — pyrite, the iron sulphide mineral known as fool's gold, that incorporates cobalt into its crystal structure in quantities that make it economically significant as a cobalt ore. abundant in copperbelt ore bodies, particularly in the transitional zone between primary sulphide ore and oxidised surface material. the chambishi metals plant processes cobaltiferous pyrite residues from multiple copperbelt smelting operations, recovering cobalt from material that would otherwise represent waste.

heterogenite — cobalt oxyhydroxide, CoO(OH) — the primary cobalt mineral in the oxidised zone of the ore bodies, where centuries of weathering have transformed primary cobalt sulphides into oxide and hydroxide minerals. the mineral that artisanal cobalt miners in the DRC's katanga province have been recovering from shallow pits for years. its vivid black colour against the red oxide soil of the weathered ore zone makes it visually distinctive and recoverable without sophisticated mineralogical knowledge.

why so much cobalt in the katangan basin?

cobalt behaves geochemically like nickel and iron — comparable ionic radius, substitutes for them in mineral structures easily. in the reducing chemical environment of the katangan basin sediments — the same environment that concentrated copper sulphides — cobalt was preferentially scavenged from circulating hydrothermal fluids and incorporated into the sulphide minerals precipitating at the redox front. copper and cobalt co-deposited in proportions that vary across the ore body but consistently make cobalt a significant and recoverable by-product of copper mining.

the average cobalt content of zambian copper ore is modest — typically a fraction of a percent. but the ore bodies are so large that even modest cobalt grades represent enormous absolute quantities of recoverable cobalt. nkana. nchanga. mufulira. chambishi. each produces cobalt alongside copper in quantities that aggregate to make zambia the world's second largest cobalt producer after the DRC.

the geology is not separate from the copper geology. it is the same geology, expressing itself in two metals simultaneously.

the copperbelt has always been a cobalt belt. it has simply not been described that way. 🔵
