Purchasing Pink Kunzite From Gem Resources:įaceted parcels of Pink Kunzite are available at $12.00 per carat, in 5 carat parcel increments only. Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect. Kunzite should also be protected from heat as well as continued exposure to strong light which may gradually fade the color. A sharp blow, if it lands in the wrong place, can break it in two. However, Kunzite should be handled with care because, like diamond, it has a distinct cleavage. Kunzite is relatively hard, with a hardness of seven just like quartz. Stones should be at least ten carats to be really in the pink. Although kunzite found in most jewelry is smaller, kunzite shows the best color in larger sizes. The largest faceted kunzite is an 880-specimen on display at the Smithsonian Institute in Washington D.C. Kunzite is often found in association with Morganite and pink tourmaline, the other popular pink gemstones. Today, most kunzite is mined in Brazil, Afghanistan, and Madagascar. Morganite was named for the customer, J.P. The name was a brilliant marketing move: the miners named the gem after its most likely customer Kunz. But the first commercially significant deposit was discovered in 1902 in the Pala region of California, where Morganite beryl was also first discovered. Kunzite was first found in Connecticut, USA. Kunz, the author of The Curious Lore of Precious Stones, searched the globe for new varieties and new deposits of gemstones, during which he learned of the old stories and legends about gems.
The name is in tribute to George Kunz, the legendary gem scholar and gemologist, who, at the turn of the century, was a gem buyer for Tiffany & Co. Even the name has American roots: it is pink gem variety of the mineral spodumene. Surprisingly Kunzite was discovered in the United States, early in the twentieth century. Affordable and available in large sizes, this icy pink to lilac gem is a perfect complement to all the pastels in your wardrobe and also stunning against black. With fashion always in the mood to think pink, Kunzite is a fashion favorite. 1911.Doubly Refracting (bi-refraction) : 0.015 Media related to Petalite at Wikimedia Commons.Exotic mineralogy: Or, Coloured figures of foreign minerals: As a supplement to British mineralogy.

and Klein, Cornelis, 1985, Manual of Mineralogy, Wiley, 20th ed., pp. The colorless varieties are often used as gemstones. Petalite (and secondary spodumene formed from it) is lower in iron than primary spodumene, making it a more useful source of lithium in, e.g., the production of glass. Petalite is an important ore of lithium, and is converted to spodumene and quartz by heating to ~500 ☌ and under 3 kbar of pressure in the presence of a dense hydrous alkali borosilicate fluid with a minor carbonate component. It occurs in lithium-bearing pegmatites with spodumene, lepidolite, and tourmaline. Petalite occurs as colorless, pink, grey, yellow, yellow grey, to white tabular crystals and columnar masses. Petalite, also known as castorite, is a lithium aluminum phyllosilicate mineral Li Al Si 4 O 10, crystallizing in the monoclinic system.
