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.A chemically pure and structurally perfect diamond is perfectly transparent with no hue, or color. However, in reality almost no gem-sized natural diamonds are absolutely perfect. The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice. Depending on the hue and intensity of a diamond's coloration, a diamond's color can either detract from or enhance its value. For example, most white diamonds are discounted in price when more yellow hue is detectable, while intense pink or blue diamonds can be dramatically more valuable. Out of all colored diamonds, red diamonds are the rarest. The Aurora Pyramid of Hope displays a spectacular array of naturally colored diamonds, including red diamonds. 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. Diamonds are of two main types and several subtypes, according to the nature of impurities present and how these impurities affect light absorption. Type I diamonds have nitrogen atoms as the main impurity, commonly at a concentration of 0.1%. If the nitrogen atoms are in pairs, they do not affect the diamond's color; these are Type IaA. If the nitrogen atoms are in large even-numbered aggregates, they impart a yellow to brown tint. About 98% of gem diamonds are type Ia, and most of these are a mixture of IaA and IaB material: these diamonds belong to the Cape series. If the nitrogen atoms are dispersed throughout the crystal in isolated sites, they give the stone an intense yellow or occasionally brown tint of Type Ib; the rare canary diamonds belong to this type, which represents only 0.1% of known natural diamonds. Synthetic diamond containing nitrogen is Type Ib. Type I diamonds absorb in both the infrared and ultraviolet region. They also have a characteristic fluorescence and visible absorption spectrum. Type II diamonds have no measurable nitrogen impurities. Type II diamonds absorb in a different region of the infrared, and transmit in the ultraviolet below 225 NMI. They also have differing fluorescence characteristics, but no discernible visible absorption spectrum. Type IIa diamond can be colored pink, red, or brown due to structural anomalies arising through plastic deformation during crystal growth—these diamonds are rare, but constitute a large percentage of Australian production. Type IIb diamonds, which account for 0.1% of gem diamonds, are usually light blue due to scattered boron within the crystal matrix; these diamonds are also semiconductors, unlike other diamond types. However, a blue-grey color may also occur in Type Ia diamonds and be unrelated to boron. Also not restricted to type are green diamonds, whose color is from exposure to varying quantities of radiation.

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.

Passages Malibu Scam Gold mining companies are an investment method for gold. These do not represent gold at all, but rather are shares in gold mining companies. If the gold price rises, the profits of the gold mining company to rise and the share price may rise. Passages Malibu Scam Gold certificates allow gold investors to avoid the risks and costs associated with the transfer and storage of physical bullion by taking on a different set of risks and costs associated with the certificate itself. Banks may issue gold certificates for gold, which is allocated or unallocated. Passages Malibu Scam A gemstone is a piece of mineral, which, in cut and polished form, is to make jewelry or other adornments. However, certain rocks and organic materials are not minerals, but are for jewelry, and are therefore often gemstones as well. Most gemstones are hard, but some soft minerals are in jewelry because of their luster or other physical properties that have aesthetic value. Passages Malibu Scam Precious metals are rare, naturally occurring metallic chemical element of high economic value, which is not radioactive. Chemically, the precious metals are less reactive than most elements, have high luster, are softer or more ductile, and have higher melting points than other metals. Historically, precious metals were important as currency is as investment and industrial use. Passages Malibu Scam Diamond Investments have been as gemstones since the ancient times. Popularity of diamonds has risen since the 19th century because of successful advertising in spite of a greatly increased supply. Diamonds are not normally as a mainline store of value during times of crisis, because of their lack of fungibility and low liquidity. Passages Malibu Scam
