The interplanar spacing or interplanar distance is the perpendicular distance between two successive planes on a family ( hkl ). It is commonly indicated as dhkl and corresponds to the reciprocal of the length of the corresponding vector in reciprocal space : where G * is the metric tensor in reciprocal space and T stands for transposed vector.

Kyanite varies in hardness according to the cleavage of its crystals. For detailed physical properties, see silicate mineral (table). Kyanite is one of the many phases in the aluminum silicate (Al 2 OSiO 4) system and can only form stably …

Kyanite has a distinct property called anisotropism. you will notice variable hardness in the same crystal and a habit of blotching or streaking of color in a single piece of jewelry. This is what sets it apart from other gems. You should be able to ascertain whether it has two distinctly different hardness values.

Kyanite's energy is easily accessible, gentle, and balanced, making it an excellent crystal for meditation. It allows for a rapid transition into a deep meditative state, and is quite useful in accessing the astral plane …

Kyanite is named after Greek word for "blue", because of its colour. Some fine specimens have sapphire-blue colour with violet pleochroism. Kyanite has a wide variations of hardness in the same crystal depending on direction (across or along axes). It complicates the cutting of this material. Cut stones reach 10 - 15 carats.

Meaning and Uses of Kyanite. Kyanite is a powerful stone with many helpful applications. It has a calming, grounding energy, making it useful for balancing emotions as well as accessing meditative states. It can also help us connect to our intuitive abilities and recall dreams, and it opens the third eye chakra. Kyanite helps us find clarity.

Kyanite is further credited with the ability to promote and maintain inner peace, tranquillity, and harmony, making it a popular healing tool for sleep disorders. It is believed that kyanite targets build-ups of mental and emotional stress, dissolving them and allowing bodily energy to flow uninhibited. We carry our various strains and burdens ...

Order in the Triclinic System: In designating forms in the Triclinic System, most crystallographers use 1st through 4th order labels. 1st, 2nd, and 3rd order labels are applied to pinacoids that intercept two of the axes and are parallel to the third axis. 1st order denotes forms parallel to the a-axis. 2nd order is parallel to the b-axis. 3rd ...
