GOLDEN CALCITE SUN Calcite (CaCO₃), a carbonate mineral, one of = 6.957×105KM the most common minerals occurs in a great 1R variety of shapes and colors, and it constitutes a major portion of many of the earth’s rocks. Calcite was used in World War II S6 for gun sights MERCURY LABRADORITE AU Labradorite ((Na,Ca)₁₋₂Si₃₋₂ O₈), a sodium-rich 0.4 plagioclase feldspar which displays a particular type of iridescence on a dark ground. Labradorite is found in igneous rocks, both plutonic and volcanic. Material was first discovered Ci in the Isle of Paul , 1770 NEPHRITE JADE VENUS Nephrite (Ca₂(Mg,Fe)₅Si₈O₂₂ (OH)₂,), a variety of the AU calcium, magnesium, and iron rich amphibole minerals 0.7 tremolite or actinolite, mostly known for its green varieties. Nephrite Jade was used mostly C2h in China & New Zealand, pre-1800 EARTH SODALITE AU Sodalite (Na₈Al₆Si₆O₂₄ Cl₂), a sodium 1.0 aluminum silicate chloride in the Sodalite group with an isometric crystal system, royal blue forms are the best known. As a mineral, it is a principal component of lapis lazuli. Material was first discovered Td in Greenland, 1811 MAHOGANY OBSIDIAN MARS Mahogany Obsidian (SiO₂), a volcanic glass which AU contains undulating parts of oxidized Hematite or 1.5 Magnetite, which are usually colored mahogany brown or brick red within a black-colored base material. Obsidian can only form near active volcanoes TIGER’S EYE JUPITER Tiger’s Eye (SiO₂), a metamorphic rock with AU a golden to red-brown colour lustre. It is 5.2 formed when the Quartz takes over and dissolves the Crocodolite, leaving the Quartz in a finely fibrous and chatoyant form. Tiger’s eye was first discovered D3 in South Africa, the early 1800s SATURN CALCITE AU Calcite (CaCO₃), a carbonate mineral, one of the most 9.5 common minerals occurs in a great variety of shapes and colors, and it constitutes a major portion of many of the earth’s rocks. Calcite was used in World War II S6 for gun sights AMAZONITE URANUS AU Amazonite (KAlSi₃O₈), a mineral of limited occurrence. Formerly it was obtained almost exclusively in the 19.2 Ilmensky Mountains. For many years, the source of amazonite’s color was a mystery. Amazonite was named after Ci The Amazon River NEPTUNE SYNTHETIC CAT’S EYE AU Synthetic material, a glass material exhibits a rare optical 30.1 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’. Same material used in Fiber-optic communication HELIOTROPE PLUTO Heliotrope (SiO₂), also known as bloodstone, AU is a variety of jasper or chalcedony (which is 39.5 a mixture of quartz). It often has an uneven color distribution, with red streaks and spots. Heliotrope is a very porous stone D3 Which reject it’s polish in water.
