Ingredients sapphire
Sapphire is one of the most beautiful gemstones and itself in the world, and this gemstone is characterized by its distinctive bright red color and is considered one of the varieties of metal Corundum, which is a transparent metal in the case of purity, and this metal is made of aluminum oxide material, the name of sapphire in English: "Ruby" for its Latin name: "Ruby", which means red.
Chemical and crystalline ruby composition Sapphire is chemically composed of aluminum oxide Al2O3, and in detail it consists of "aluminum by 52.9%, oxygen by 47.1%", and because of some of the effects of chromium oxide that replace aluminum oxide becomes ruby color distinctive red, but this The replacement of chromium oxide is of a formally balanced type. Cobalt nitrate drops are used to detect the quality of rubies, or their powder may be exposed to some flame. If a yellow flame is present, it indicates the quality of the rubies or "evidence of aluminum". Sapphire is characterized by the form of a hexagonal system and in the triple rhombus caste, yet the crystal structure is different with different rubies. Physical properties of rubies One of the most important features that characterize rubies
It ranks ninth in hardness according to Mohs scale, the specific weight of this stone is 4, and it is characterized by its diamond-gum gloss, a stone that is in a transparent-semi-transparent state, and the sapphire is colored by the presence of small amounts of chromium oxide, and the proportion is in the rate Only 0.1-2% is present in all shades of red. It is found in light pink and ruby red. Sapphires have a distinctive and rare color known as red "pigeon blood", which is made up of only 1% of chromium oxide. In Burma
. Sapphires, sapphires, and corundum are abundant in metamorphic rocks, especially in limestone that crystallizes with different minerals, the "Nice Mystic Chest", and sapphires are the main components of cyanite and nephylene cyanite. It differs in the form of crystals within pegmatite rocks, and sometimes in crystals within the soil and river sand, due to its high hardness and chemical inertness. Sapphires are available in many regions of the world, but they are common in Burma, Siam, Sri Lanka, Kashmir, Australia, the United States, Tanzania, and Malagasy.Rubies are currently manufactured in many countries in the world with good specifications and low prices.
