~Fire Obsidian~

Fire Obsidian is the fusion of Rhodonite (Pearl and Ruby), Emerald, Peridot and Carol. Fire Obsidian is a massive fusion with eight arms, glowing rainbow eyes, gray skin, and slightly pointed charcoal-black hair that reaches their feet. The skin and hair have bright rainbow markings. Carol's clothes can be seen on one of Fire Obsidian's hands, a reference to where Carol's laundry is hanged in the Crystal Palace.

~By the way, thanks for the 40 followers, it's still hard to believe how fast this number grows, not even a month ago this tumblr was created, and thanks to you guys, thanks for everything <3

🔥Rhodonite and Fire Obsidian🔥

Rhodonite- Rhodonite is a gem from homeworld who made statues out of lava and igneous rock. She would make them for the diamonds and elite gems, like emeralds. She is against era 3's new ways and rebels with Steven at times.

Fire Obsidian- Fire obsidian is a gem who works with rhodonite to make statues and sculptures. Fire obsidian even made a castle, all for herself and rhodonite. She isn't really against the new rules, she just hates the rule where fusions are aloud.

Bonus:

(I was out of time so I just used their png's)

Fire Obsidian is an iridescent variety of obsidian from Glass Buttes, Oregon.

James Miller, a geologist in Redmond, Washington, is an avid “knapper,” meaning he chips stone to make tools, the very old-fashioned way. During a search for material, he came across some obsidian that shimmered colorfully in direct light. It didn’t look like striped rainbow obsidian, but instead hosted flame-like patterns in the glass. Wanting to know more, he sent a few samples to George Rossman and Chi Ma for their spectroscopic studies.

Under bright light, fire obsidian reflects brilliantly colored streaks resembling an iridescent oil slick. When thinned to a translucent blade, dark, wispy flames can be seen through the glass. Rossman suspected the layers of “fire” were made of tiny particles that increased the refractive index in the layer, giving rise to another manifestation of thin-film interference. “Out of curiosity, we said, ‘Well, let’s take a look at it and find out what it is,’” he recalls. At 100,000 times magnification, they found their answer—a wave of white, snowflake-like nanoparticles were suspended in the glass.   Electron back-scatter diffraction (EBSD) analyses revealed that these flakes were the mineral magnetite, an iron oxide.

--The Secret Lives of Minerals, Elizabeth Nadin

The black obsidian without thin layers from Glass Buttes contains evenly distributed inclusions of magnetite. The darker the black obsidian, the more numerous the magnetite crystals or the larger the crystals are in size. Where the magnetite inclusions concentrate to form thin layers of a submicrometric thickness, the “fire” coloration may appear. Measurements of the layer thickness and the estimated index of refraction indicate that some of the layers are of an appropriate thickness to cause thin-film interference. The layers have both a higher calculated index of refraction than the host obsidian and have a thickness slightly less than the wavelength of visible light. Such conditions are ideally suited to giving interference colors similar to those from a thin slick of oil on water.

A commission (yes you read that right) for @devidaydreamer for my take on a Fire Obsidian and here she is! 

I hope you like it!

Decided my own Obsidian! Fire Obsidian!

I know I don’t usually include pics of the irl gem but it was just to gorgeous not to. Fire Obsidian’s personality is very similar to Bismuth’s, and she loves to fight, however, she isn’t very smart and is very gullible. You could say almost anything is an enemy and she’ll fight it. A desk, a pencil, and even a mountain. She, however, won’t fight her fellow crystal gems.
