Pezzottaite (Defective)

Pezzottaite is a defective Crystal Gem and an original character made by BlueWhiteLight.

Appearance
Pezzottaite is smaller than other Pezzottaites and has a stubby build. She has a light pink complexion with a long ahoge and long pink hair. She seems to have no eyes, which is replaced with her gemstone. She wears a pink singlet and elbow-length gloves. Her gemstone is located where her eye would be.

Personality
Pezzottaite is loving and caring, especially to Orange Beryl.

Abilities
Pezzottaite possesses standard Gem abilities including bubbling, shapeshifting, fusion, regeneration, agelessness and superhuman strength/durability, despite being defective.
 * Healing Pulse: Pezzotaite can heal organic injuries and cracked gemstones.

Trivia

 * According to BlueWhiteLight, Pezzottaite and Orange Beryl, in his corrupted form, would confirm the existence of the Hidden Crystal Gems to the Crystal Gems.

Gemology


Gemstone Information

Pezzottaite, marketed under the name raspberyl or raspberry beryl, is a newly identified mineral species, first recognized by the International Mineralogical Association in September 2003. Pezzottaite is a caesium analogue of beryl, a silicate of caesium, beryllium, lithium and aluminium, with the chemical formula Cs(Be2Li)Al2Si6O18. Named after Italian geologist and mineralogist Federico Pezzotta, pezzottaite was first thought to be either red beryl or a new variety of beryl ("caesium beryl"); unlike actual beryl, however, pezzottaite contains lithium and crystallizes in the trigonal crystal system rather than the hexagonal system.

Colors include shades of raspberry red to orange-red and pink. Recovered from miarolitic cavities in the granitic pegmatite fields of Fianarantsoa province, southern Madagascar, the pezzottaite crystals were small—no more than about 7 cm (2.8 in) in their widest dimension—and tabular or equant in habit, and few in number, most being heavily included with growth tubes and liquid feathers. Approximately 10 per cent of the rough material would also exhibit chatoyancy when polished. Most cut pezzottaite gems are under one carat (200 mg) in weight and rarely exceed two carats (400 mg).

With the exception of hardness (8 on Mohs scale), the physical and optical properties of pezzottaite—i.e., specific gravity 3.10 (average), refractive index 1.601 to 1.620, birefringence 0.008 to 0.011 (uniaxial negative)—are all higher than typical beryl. Pezzottiate is brittle with a conchoidal to irregular fracture, and streaks white. Like beryl, it has an imperfect to fair basal cleavage. Pleochroism is moderate, from pink-orange or purplish pink to pinkish purple. Pezzottaite's absorption spectrum, as seen by a hand-held (direct vision) spectroscope, features a band at 485–500 nm with some specimens showing additional weak lines at 465 and 477 nm and a weak band at 550 to 580 nm.

Most (if not all) of the Madagascan deposits have since been exhausted. Pezzottaite has been found in at least one other locality, Afghanistan: this material was first thought to be caesium-rich morganite (pink beryl). Like morganite and bixbite, pezzottaite is believed to owe its color to radiation-induced color centres involving trivalent manganese. Pezzottaite will lose its color if heated to 450 °C for two hours, but the color can be restored with gamma irradiation.
