Triclinic:
In triclicnic crystal system, both the length and angle of intersection all the three crystallographic axes are of different length and different angles respectively.
Triclinic: Having three unequal crystal axes intersecting at oblique angles
Trilliant: See Trillion-cut.
Trillion-cut: A brilliant-cut gemstone that is triangular in shape rather than round with 44 facets.
Triclinic Crystals of the triclinic system are referred to three unequal axes, all of which intersect at oblique angles. None of the axes are perpendicular to any other axis.
Triclinic System
A crystal system which consists of three axes, all of unequal lengths and at oblique angles to each other.
Triscotahedron
A twenty-four sided geometric solid. One of the crystal forms of the Isometric crystal system.
TRICLINIC. The system in crystallography in which the three crystallographic axes are unequal, and inclined at angles which are not right angles, so that the forms are oblique in every direction, and have no plane of symmetry.
Triclinic, tabular crystals, often not terminated, sometimes bent or twisted, often long and flattened
Envronment:
high pressure metamorphic rocks low in Ca and rich in Al.
Triclinic crystals have three axes, all of unequal length and intersecting at angles other than 90 degrees. Examples include labradorite and microcline feldspar.

Triclinic
Crystals that form in the triclinic system have three unequal crystallographic axes, all of which intersect at oblique angles.
(6) TRICLINIC - The three axes are all unequal in length and intersect at three different angles (any angle but 90 degrees). Note: If any two axes crossed at 90 degrees, then we would be describing a monoclinic crystal! Discussed in part 8.

Turquoise has been found only in one location in distinct crystals of the triclinic system in 1912 in Lynch, Virginia, U.S.A.
The five other systems are hexagonal, trigonal, orthorhombic, monoclinic, and triclinic. Along with composition, crystal structure determines a mineral's properties.
Biaxial
The character of crystals from the monoclinic, rhombic, triclinic system which show double refraction but have two direction of single refraction.
Binding
Two or more metal part are fixed together with a metal wire, for soldering.
Oligoclase: (Also called Plagioclase) A triclinic feldspar made of soda-lime.
Olivelia Shells: A kind of seashell used for Heishi necklaces.
Olivine: See Chrysolite and Peridot.
28 (tavorite belongs to the Amblygonite Group, phosphates that have a triclinic crystalline structure). Tavorite was named in 1955 by the mineralogists M. L. Lindberg & W. T. Pecoria for the Brazilian mineralogist Elysairio Tavora (1911- ).

Biaxial...Two optic axes or double refraction. Usually crystals in the rhombic, monoclinic, and triclinic system.
Bipyramid (dipyramid)...Crystals that form symmetrically about a plane dividing it into two pyramids.
The chemical name of Axinite is Calcium Manganese Iron Magnesium Aluminium Borosilicate Hydroxide. It is basically triclinic in structure, characterized by the absence of symmetry surfaces. The crystals can be either transparent or translucent.
Luster: Vitreous to silky
Transparency: Transparent to translucent
Crystal System: Triclinic
Fracture: Splintery due to the cleavage
Streak: White.
Rhodonite is a manganese silicate and forms in the triclinic crystal system. It occurs in both a crystallised and massive, fine-grained form.It is deep pink to red and opaque, with dark veins of manganese lending some patterning.
Different Types Of Quartz Crystal
There are six main groups into which crystals can be classified: triclinic, monoclinic, orthorhombic, cubic, tetragonal and hexagonal.
Since axinite develops in the triclinic crystal system with its low degree of symmetry, and its angles are very acute.
Triclinic System - Crystallization system having three unequal axes at oblique angles to each other. (Microcline, Rhodonite)
Trilling - A cyclical twin made up of three crystals, generally forming a hexagonal outline. (Crysoberyl) ...
Double refraction occurs in specimens from five of the six crystal systems, including tetragonal, orthorhombic, hexagonal, monoclinic, and triclinic.
The internal atomic structure of a crystal. All crystalline gems may be classified in one of seven groups according to the symmetry of their structure: cubic, tetragonal, hexagonal, trigonal, orthorhombic, monoclinic, and triclinic.
