    Calcite was used in World War II for gun sights

    Golden Calcite

    Calcite (CaCO₃), a carbonate mineral, one of the most common minerals occurs in a great variety of shapes and colors, and it constitutes a major portion of many of the earth’s rocks.

    Origin and occurrence: Calcite is a very abundant mineral found in the Earth’s crust. It is found in sedimentary rock. It is usually mined from deep underground or quarried from the surface of the Earth which can be found in various countries in the world including Mexico, the US, England, India, and Germany.

    Sodalite

    Sodalite (Na₈Al₆Si₆O₂₄ Cl₂), a sodium aluminum silicate chloride in the Sodalite group with an isometric crystal system. Its royal blue forms are the best known. As a mineral, it is a principal component of lapis lazuli.

    Origin and occurrence: Magmatic in alkaline syenites and phonolites, associated with nepheline, zircon and titanite; hydrothermal in marbles. Granular aggregates are known from the Princess Sodalite mine, Bancroft, Ontario, Canada and Ditrau, Romania. Crystals up to 100 mm across come from Kangerdluarssuk, Greenland.

    TIGER’S EYE WAS FIRST DISCOVERED SOUTH AFRICA, THE EARLY 1800S

    Tiger’s Eye

    Tiger’s Eye (SiO₂), a metamorphic rock with a golden to red-brown colour lustre. It is formed when the Quartz takes over and dissolves the Crocodolite, leaving the Quartz in a finely fibrous and chatoyant form.

    For more than a century, textbooks and museum displays have identified the material as an archetype of pseudomorphism, i.e., the replacement of one mineral by another with the retention of the earlier mineral’s shape. Rather, we argue that tiger’s-eye classically exemplifies synchronous mineral growth through a crack-seal vein-filling process.

    AMAZONITE WAS NAMED AFTER THE AMAZON RIVER

    Amazonite

    Amazonite (KAlSi₃O₈), a mineral of limited occurrence. Formerly it was obtained almost exclusively in the Ilmensky Mountains. For many years, the source of amazonite’s color was a mystery.

    Origin and occurrence: Magmatic in granites, syenites and pegmatites; metamorphic in various rock types, as orthogneisses and migmatites: hydrothermal in the Alpine-type veins and ore veins; a typical rock-forming mineral. Well-formed amazonite crystals up to 40 cm across occur in pegmatite cavities in Crystal Peak, Colorado, USA.

    Synthetic Cat’s eye

    Synthetic Cat’s Eye, glass material exhibits a rare optical trait known as chatoyancy. Chatoyancy is the unique ability to reflect light in a way that resembles the slit eye of a cat, hence the name ‘cat’s eye’.

Even though the stone is man-made, it still contains the chemical properties of some types of natural glass (primarily Quartz), so it is said to possess the same metaphysical attributes. _

    Heliotrope is a very porous stone which reject it’s polish in water

    Heliotrope

    Heliotrope (SiO₂), also known as bloodstone, is a variety of jasper or chalcedony (which is a cryptocrystalline mixture of quartz).

    The red or brown spots in Bloodstone are formed by iron oxide impurities, especially Hematite. The solid green color is caused by dense inclusions of Chlorite or amphibole minerals inside the Chalcedony. The base color of Bloodstone may be bluish-gray, but it often has an uneven color distribution, with red streaks and spots.
