Sergei

Serendibite commonly adressed as Sergei and less frequentlySiren is a fandom created Gem by Japkot. They are non-canon. They have made their first appearance on the Chapter 'Our New Arrival' in the Fanfiction called 'What Binds Us'
They were created on Homeworld as an upgrade to the Quartz Warriors, and were sent to Earth as a means to test them on the remaining Crystal Gems. But something happened that none thought to be possible.
Not even the Diamonds themselves could explain...
== Appearance ==
Beside the set facial features, Sergei has long, unruly hair that reaches the small of his back, unlike Serendibite, it sticks out toward all directions and you could probably lose a lot of stuff in it.
Unlike the other two, Sergei has fangs, this is because of the additional intimidation value.
Beside his rebellious nature, Sergei is very compassionate and it shows on his neutral expression, but there's a lot of anger hidden behind that psuedo-mask so much so, that you could probably spot if you looked hard enough.
He prefers to look 'male' because of his rebellious nature, it can be summed up as him being against everything homeworld stands for, due to all the pain he suffered while he was still a part of Serendibite.
Clotheswise: He prefers wearing a grey plain t-shirt with the left sleeve slightly cut out to make way for his gem that is a little bit baggy, and casual black pants. Not a diamond in sight!

== Abilities ==
Serendibite is an unique gem, while they possess standard Gem abilities, including weapon-summoning, bubbling, shape-shifting, fusion, regeneration, agelessness and superhuman strength/durability. They also have a built in remote control to better serve homeworld's needs, which caused another unique feature: Creating two split personalities that act as two seperate people, and can interact with each other, but one cannot remain active while the other is still active, for they have only one gem.
Their abilities also drain a lot of energy, making them somewhat vulnerable if it ever ran out.
=== Skillset ===
* Sword Proficency: Serendibite is shown to be an excellent swordsman, able to keep up with Garnet,Amethyst and Pearl in a 3 on 1 fight on their first forming. Stunning the latter two and going toe to toe with Garnet, who was only able to beat them because of her future vision power. This combines greatly with his other powers, making him an almost unstoppable force on the battlefield, better then even the unbeatable Quartz Warriors.
** Dual Wielding: They are able to summon multiple weapons from their gem and using them prefectly, implying that they are ambidextrous.
*** Combining Swords: They can combine their swords, making it a double bleaded-spear, it is not used often, but it can be very efficent against unfavourable odds.
* Greater Agility: They move very fast, so fast that they turn into a blurry mess of colours, they can use this this to their advantage in combat.
** Precision Strikes: They are able to pinpoint weaknesses easily, striking them with dead on accuracy.
* Greater Shapeshifting: Serendibite has a greater variety of shapeshifting abilites, able to change their size to match anything height, but it drains a lot of energy in a short time. 
=== Unique Abilites ===
* Combat Observer: They are able to observe the moves of combatants, only combatants, and use them in their favour, either coming up with strategies to defeat them or using their moves to their advantage in eliminating them
* Telekinesis: They are able to use Telekeinesis in battle, giving them many advantages over the battlefield, this ability is used rarely due to its power drainage. Telekinesis powers have some categories:
** Telekinetic Shockwave: Serendibite is able to use their telekintic manupilation for combat purposes, creating a wave that disorients or even temporarily disables opponents.
** Telekinetic Levitation: Serendibite is able to use Telekinesis to lift things, but bigger the thing, bigger the energy use.
==History==
Not much is known about Serendibite's history. Except they were a prototype for the Project 'Facet 0' that 
if were to succeed would be the start of a whole new type of gem production, even replacing the Quartz Gems as the most efficent soldier gem.
It is revealed that for the Serendibite to properly incubate, injector drills was shot at a star, sucking it dry of energy for a thousand years, an unique feature, given that the rest of the gems are made from draining organic energy.
With this soldier type homeworld went for %100 precent efficency and 0% precent individuality. Giving instructions to Peridot and Jasper that they would be treated like a weapon not a proper gem person. They first reformed on the Gem Spaceship.

== Trivia ==

== Gemology ==
* Serendibite was discovered at Gangapitiya, near Ambakotte, Sri Lanka, in 1902 by G.T. Prior and A.K. Coomaraswamy. Prior and Coomaraswamy named the mineral ‘serendibite,’ which is derived from ‘serendib,’ an old Arabic term for Sri Lanka.
* Serendibite is rarely found as facet-grade material. Before the 2005 discovery of serendibite in Mogok, Myanmar, there were only 3 known faceted serendibites, which were from the original Sri Lankan find. The serendibite from Sri Lanka and Myanmar is believed to be the only sources for facet-grade material. Sri Lankan Serendibite was an attractive greenish or violet-blue, while the stones from Myanmar are dark black.
* In the second half of the 1990’s, gem-quality serendibite was discovered from secondary deposits in the Ratnapura area of Sri Lanka.
* The rare gem material, serendibite, is characterized with regard to gemological, chemical, and spectroscopic properties. Spectroscopic features such as US-Vis-NIR and infrared ranges, as well as Raman and photoluminescence data, are considered more for identification of serendibite.
* Serendibite may be confused with sapphirine and zoisite due to similarity in color and almost identical properties but refractive indices, twinning, and spectra can be used to separate these gem materials.
* The distinction from sapphirine and the known low-bearing, gem-quality serendibite can be made by careful measurement of refractive indices, with sapphirine having a higher refractive index of 1.700. Higher contents of iron in serendibite may cause misleading refractive index readings and may require further gemological examinations such as spectroscopy and microscopy.
* The optical properties and specific gravity of serendibite and zoisite may completely overlap. The color of the chromium and chromium-bearing Tanzanian zoisite is quite similar to serendibite. A distinction may be made on the basis of the lamellar or polysynthetic twinning of gem-quality and non-gem quality serendibite samples from various locations.
* Combination of calcium, magnesium, aluminum, silicon, boron and oxygen.
== Gemstone ==
It stands one their left shoulder, perfect for summoning the sword as it stands on the shoulder like a sheath, shoulder-pad. It has an unique blue hue to it, but it is mostly black.
It has several, trapezoidic facets along its surface. no cuts that can be seen.
