Pink Sapphire

Sapphire is a gemstone variety of the mineral corundum, an aluminium oxide (α-Al2O3). Trace amounts of other elements such as iron, titanium, chromium, copper or magnesium can give corundum blue, yellow, pink, purple, orange or greenish color. Chromium impurities in corundum yield a red tint, and the resultant gemstone is called a ruby.

 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 tending towards the red of rubies.
 
Even for people who aren’t fans of the color pink there’s no argument that the pink sapphire is one of the most beautiful gems in the world. Although yellow gold is a favorite setting for most gems, when a pink sapphire is set in a white gold mounting or platinum mounting, it becomes truly a gorgeous gemstone to behold. 
 
Pink Sapphire History
The pink sapphire is not only a gorgeous gemstone, it’s also the birthstone of September and is often associated with the zodiac signs of Aries, Cancer, Libra, and Taurus. Over the millenniums kings and religious figures both used pink sapphires, and other colors such as blue sapphire gems, for reasons beyond their beauty. Many of them believed the pink sapphire offered protection from evil, increased physical health and greater power, not to mention being a link to the sub-conscious mind. Even to this day there are still cultures where the pink sapphire is revered for these qualities and feel it attracts divine favor. Many modern spiritualists believe the pink sapphire can take negative emotions and transforming them into positive ones like contentment, love or joy. 

 

Blue Sapphire

Color in gemstones breaks down into three components: hue, saturation, and tone. Hue is most commonly understood as the "color" of the gemstone. Saturation refers to the vividness or brightness or "colorfulness" of the color, and tone is the lightness to darkness of the color. Blue sapphire exists in various mixtures of its primary (blue) and secondary hues, various tonal levels (shades) and at various levels of saturation (vividness).

Blue sapphires are 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 is considered to be distinctly negative. Blue sapphires with up to 15% violet or purple are generally said to be of fine quality. Blue sapphires with any amount of green as a secondary hue are not considered to be 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 can be 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 Sapphire

Fancy Sapphire

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'

Ruby

A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium. Its name comes from ruber, Latin for red. The ruby is considered one of the four precious stones, together with the sapphire, the emerald, and the diamond.

Prices of rubies are primarily determined by color. The brightest and most valuable "red" called pigeon blood-red, commands a huge premium over other rubies of similar quality. After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions may indicate that the stone has been treated. Cut and carat (weight) are also an important factor in determining the price.
Emerald

Emerald refers to the green variety of beryl. There are however, gem quality green beryls which are not emeralds. All emeralds contain inclusions, which are evidence as to the genuineness of the stone. The name is derived from the Greek word Smaragdos, meaning "green stone". Emerald is the birthstone of the month of May.

Diamond

The name diamond is derived from the ancient Greek αδάμας (adámas), "proper", "unalterable", "unbreakable", "untamed", from ἀ- (a-), "un-" + δαμάω (damáō), "I overpower", "I tame".

Diamonds are thought to have been first recognized and mined in India, where significant alluvial deposits of the stone could be found many centuries ago along the rivers Penner, Krishna and Godavari. Diamonds have been known in India for at least 3,000 years but most likely 6,000 years.

The normal range of colors in diamonds run from colorless to slightly yellow or brown. "Fancy colors" are those colors outside the normal range, and are found in all colors. The most sought after are colorless, and the more intense "fancy colors", blue, pink and red. Red diamonds are among the rarest of all gemstones, only two are known to exist.

Pearl

Pearls are characterized by their translucence and lustre and by a delicate play of surface colour called orient. The more perfect its shape (spherical or droplike) and the deeper its lustre, the greater its value. Only those pearls produced by mollusks whose shells are lined with mother-of-pearl (e.g., certain species of both saltwater oysters and freshwater clams) are really fine pearls; pearls from other mollusks are reddish or whitish, porcellaneous, or lacking in pearly lustre. Jewelers commonly refer to saltwater pearls as Oriental pearls and to those produced by freshwater mollusks as freshwater pearls.

Cats Eye

cat’s-eye,  any of several gemstones that, when cut en cabochon (in convex form, highly polished), display a luminous band reminiscent of the eye of a cat; this particular quality is termed chatoyancy. Precious, or oriental, cat’s-eye, the rarest and most highly prized, is a greenish chatoyant variety of chrysoberyl called cymophane; the chatoyant effect is due to minute parallel cavities. Quartz cat’s-eye, the commonest, owes its chatoyancy and grayish-green or greenish colour to parallel fibres of asbestos in the quartz; although it comes from the East, it is often called occidental cat’s-eye to differentiate it from the more valuable oriental (chrysoberyl) cat’s-eye. The two may be distinguished by their specific gravities; chrysoberyl is much denser. Crocidolite cat’s-eye (African cat’s-eye), more commonly known as tigereye (or tiger’s-eye), is quartz that contains oriented fibres of crocidolite that have been replaced by silica. Corundum cat’s-eye is an imperfect star sapphire or ruby in which the star is reduced to a luminous zone.

Tanzanite

Tanzanite is a relatively new gemstone, discovered in 1967.  It is said that Masai tribesmen walking through the plains of Tanzania came across a stone that was seen to be hit with lightning.  This mineral was Zoisite and the mineral was a beautiful deep blue with a tinge of purple surrounding the center.  This new mineral was later named Tanzanite with the help of Tiffany’s and Co. and from this point on became a favorite of the jewelry marketplace.

 It is an extraordinary mineral in that it gives off a wonderful hue, most notably deep blue with a hint of purple.  However it can come in other colors as well including purple or brownish yellow. 
 
Some of the stones even include a trichromism effect, meaning they can reflect three different colors depending on the angle which you look at the stone.  Usually they include a purple, blue and yellow or green.
