Mid September and the second half of facts about that blue beauty, the September gemstone,sapphire. In this article you will find that not only is sapphire blue in color but it comes in other colors as well. All spectacular treasures once crafted into jewelry.
Sapphires are commonly worn as jewellery. Sapphires can be found naturally, by searching through certain sediments or rock formations, or they can be manufactured for industrial or decorative purposes in large crystal boules. Because of the remarkable hardness of sapphires (and of aluminum oxide in general), sapphires are used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; small, high-durability windows (also used in scientific instruments); wristwatch crystals; and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics (most of which are integrated circuits). Natural sapphires
An uncut/rough yellow sapphire found at the Spokane Sapphire Mine near Helena Montana.
The sapphire is one of the two or three gem-varieties of corundum, with another one being the red or deep pink ruby. Although blue is their most well-known hue, sapphires are made up of any color of corundum except for red (red ones are called rubies). Sapphires may also be colorless, and they are also found in shades of gray and black.
The cost of natural sapphires varies depending on their color, clarity, size, cut, and overall quality - as well as their geographic origin, oddly enough. Significant sapphire deposits are found in Eastern Australia, Thailand, Sri Lanka, Madagascar, East Africa, and in North American at a few locations, such as at "Gem Mountain", and in or near the Missouri River in the region around Helena, Montana. Sapphire and rubies are often found together in the same area, but one gem is usually more abundant.
Fancy color sapphire
Yellow and green sapphires are also commonly found. Pink sapphires deepen in color as the quantity of chromium increases. The deeper the pink color the higher their monetary value as long as the color is trending towards the red of rubies.
Sapphires also occur in shades of orange and brown, and colorless sapphires are sometimes used as diamond substitutes in jewelry. Padparadscha sapphires often draw higher prices than many of even the finest blue sapphires. Recently, more sapphires of this color have appeared on the market as a result of a new artificial treatment method that is called "lattice diffusion"
In our fair city we can only see sapphire in its finished form as breathtaking pieces of jewelry and the best way for anyone to admire this precious gem is to check out the special display cases at SOPHIA JEWELLLERY which features the sapphire this month. Don’t miss out on that and if you are a gemstone buff, collect these articles which will tell you all and more or as much information about a gemstone as I can gather.
