Sapphire is a gemstone variety of the mineral corundum, an aluminum oxide, when it is a color other than red or dark pink, in which case the gem would be a ruby, considered a different gemstone. Trace amounts of other elements such as iron, titanium, or chromium can give corundum blue, yellow, pink, purple, orange, or greenish color. Pink-orange sapphires are padparadscha. Pure chromium is the distinct impurity of rubies. However, a combination of e.g. chromium and titanium can give a sapphire of a color distinct from red. Sapphires are a part of many jewelry settings. Sapphires found naturally by searching through certain sediments or rock formations, or manufactured for industrial or decorative purposes in large crystal boles. Because of the remarkable hardness of sapphires , sapphires are used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; small, high-durability windows ; wristwatch crystals; and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics . 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 known color, sapphires make up of any color of corundum except for red. Sapphires may also be colorless, and 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 America in a few locations, such as at Gem Mountain, and in or near the Missouri River in the region around Helena, Montana. Sapphire and rubies found together in the same area, but one gem is usually more abundant. Color in gemstones breaks down into three components: hue, saturation, and tone. Hue is the color of the gemstone. Saturation refers to the vividness, brightness, or colorfulness of the hue and tone is the lightness to darkness of the hue. Blue sapphire exists in various mixtures of its primary and secondary hues, various tonal levels and at various levels of saturation. Blue sapphires evaluated based upon the purity of their primary hue. Purple, violet, and green are the most common secondary hues found in blue sapphires. Violet and purple can contribute to the overall beauty of the color, while green considered distinctly negative. Blue sapphires with up to 15% violet or purple are to be of fine quality. Blue sapphires with any amount of green as a secondary hue are not fine quality. Gray is the normal saturation modifier or mask found in blue sapphires. Gray reduces the saturation or brightness of the hue and therefore has a distinctly negative effect. The color of fine blue sapphires described as a vivid medium dark violet to purplish blue where the primary blue hue is at least 85% and the secondary hue no more than 15% without the least admixture of a green secondary hue or a gray mask. Yellow and green sapphires found regularly. 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, brown, and colorless sapphires 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 result of a new artificial treatment method that is lattice diffusion.

Wedding Rings

A wedding ring or wedding band is a metal ring indicating the wearer is married. Depending on the local culture, it is on the base of the right or the left ring finger. The custom of wearing such a ring has spread widely beyond its origin in Europe. Originally worn by wives only, wedding rings became customary for both husbands and wives during the 20th century. According to some customs, the wedding ring forms the last in a series of gifts, which also may include the engagement ring, traditionally given as a betrothal present. This tradition was already in use in Ancient Rome and is possibly much older. Historically, the wedding ring connected to the exchange of valuables at the moment of the wedding rather than a symbol of eternal love and devotion. It is from the times when marriage was a contract between families. After marriage, the ring worn on the hand placed on during the ceremony. By wearing rings on the fourth finger, a married couple symbolically declares their eternal love for each other. This has now become a matter of tradition and etiquette. One interpretation states that the woman wears the wedding ring below the engagement ring, thus making it closer to the heart. Another practice holds that the woman should wear the wedding ring above the engagement ring, thus sealing the atmosphere of the engagement into the marriage. Still others prefer that the wedding ring worn alone. Further, modern ring sets in the United States are often as a three-piece set, including the man's wedding band, the woman's engagement ring, and a slender band that mounted to the engagement ring before the wedding, converting it into a single, permanent wedding ring. Some cultures exchange additional rings: In some parts of India, Hindus may use a toe ring worn instead of a ring on a finger, although this is only for women, and increasingly worn along with a finger ring. In Romania, spouses celebrate their silver wedding anniversary by exchanging silver wedding rings, which worn on the fourth finger of the left hand along with the original wedding ring. The wedding ring removed for comfort or safety. It is common for those who have professions that forbid the wearing of jewelry, such as police officers or electrical workers. In some jurisdictions, those in the food service industry may be required to remove all jewelry while handling ready-to-eat food, including wedding rings, unless they are simple, smooth rings. Physicians known to prefer smooth, simple designs, some may even autoclave their rings on a regular basis. Many times these people say they wear a "ring around their heart" not around their finger. Some will wear it on a chain around their neck to compensate for the inability to wear it on a finger.Diamonds occur in a variety of colors — steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black, virtually in every color of the rainbow. Colored diamonds contain interstitial impurities or structural defects that cause the coloration, whilst pure diamonds are perfectly transparent and colorless.
