Gemstone Review – The Gemstone Sapphire – sapphire gemstone
sapphire gemstone –
Sapphire is a precious gemstone from the corundum family. Corundum is a mineralogical term for crystallized alumina (Al2O3). Pure corundum, which is very rare, is completely colorless and therefore colorless sapphire is just as rare. Small amounts of metallic impurities (especially iron and chromium) in the crystal structure of the corundum lead to many color variants in the gemstone.
A blue gemstone made of corundum is called only sapphire.
Gems of other colors are referred to by their color as a prefix. For example yellow sapphire, pink sapphire and so on. Two other color variants have been given different names, the red ruby and the orange-pink padparadscha.
These gemstones are more appealing because of their attractive colors, rich history, and metaphysical qualities attributed to them. Legend has it that the Ten Commandments were actually made of sapphire. Ancient kings wore sapphires around their necks to protect themselves from harm, to ward off evil, and to obtain divine favors.
The ancients believed that the energy of wisdom is contained in this precious gemstone. They believed that the power of the stone enables the wearer to find the right solutions to difficult problems.
The sapphire was a symbol of heaven, protector of innocence and conveyed with loyalty, sincerity and truth. The ancient Persians believed that the earth's crust rested on a huge sapphire whose luminosity reflected the sky color at sunset.
The word sapphire comes from the Latin word sapphire, which means blue only. Ruby derives from the Latin word ruber and means red. The name Korund was derived from the Sanskrit word Kurivinda.
In antiquity, it was believed that all the gems had grown and ripened with transforming seasons, much like the fruits of a tree. As white stones, the gems began to mature and became perfect in sunshine. It was assumed that deep red stones are fully mature, while the brighter stones were picked from the earth too early. The beautiful red ripe stone (ruby) was named in the ancient Indian language of Sanskrit Kuruvinda. The term Corundum comes from this ancient Sanskrit word and includes all gems that are formed from crystallized alumina (Al2O3) together with the Ruby.
Although the most prominent sapphire color is blue (from vibrant mid-dark purple to purple blue), this gemstone comes in almost all other shades such as yellow, orange, white, pink and purple.
In addition to its color, the area of origin has a great influence on the value of a sapphire. The priceless and magnificent sapphires with intense blue color and a hint of violet come from the Indian region of Kashmir.
Sapphires in shades of Kashmir sapphire come from Burma (Myanmar).
The pink orange sapphires from Sri Lanka (formerly Ceylon) are known as Ceylon sapphires. They are also often referred to as "Padparadscha". Padparadscha sapphires are characterized by an orange hue with a subtle pink undertone comparable to that of a "lotus flower", which is their name.
Australia is another important source of sapphires that are particularly deep velvety blue and dark tinted. Some recent sources of sapphire include Madagascar, USA (Gem Mountain and Montana), Brazil, Tanzania and Cambodia.
The history of treating a gemstone to enhance its color, clarity, etc. is as old as the gemstone trade. One of the earliest references to the treatment of gemstones is in the history of the world of Pliny. It is a custom in the gem trade that pretty much all gems undergo some form of treatment. Clarity and color of a sapphire are significantly improved by heat treatment.
If you want a sapphire whose color is natural, insist on a report from an established gem testing laboratory, such as the AGTA Gemological Testing Center, which confirms that the stone has no sign of heat change. But you must also be willing to pay a premium for the pleasure.
Intense medium dark blue is the most sought after color for blue sapphires. The value of blue sapphires is determined by the purity of their primary hue. Purple, violet and green are the lesser shades that naturally occur in blue sapphires. Violet and purple shades are considered positive and contribute to the general beauty of sapphire. Conversely, the green hue is definitely negative and evaluates the value of the sapphire. Blue sapphires with less than fifteen percent purple or purple tones are considered good quality, but even a hint of green can affect quality.
Often also yellow and green sapphires are found.
The chrome content gives the sapphires a pink hue, and the pink color gets deeper as the chrome content increases. The value of sapphire increases with the deepening of the pink color, as the color deepens to the red of the rubies.
Certain rare color shift sapphires show different colors in different light. The blue of the outside light changes to purple in a glowing interior light. In daylight, the pink becomes greenish under neon light.
The value of sapphire depends more than anything on its color, and even small deviations can change its value significantly. A sapphire should preferably be alive, pure and highly saturated. Medium or medium dark tone without shades of gray or brown tones. Sapphires that are too dark or too light are not much appreciated.
All sapphires are found in nature with inclusions, although in rare cases a sapphire may be clean. Even valuable sapphires can carry inclusions and absolutely clean gems make them suspicious.
Sapphires with inclusions of tiny rutile needles have an optical property called asterism. This is the star-shaped effect seen in star sapphires and is usually only seen in cabochon cuts.
Parti sapphires are beautiful Australian beauties and the best examples are unique in Australia. They show both yellow and blue colors and, depending on the facets, also give the green color. Due to the natural color mix, Parti sapphires can not be made synthetically and offer their owners an exclusive gemstone that is guaranteed to be natural.
A much appreciated Parti sapphire is the "Pharaoh's Eye". The pharaonic eye is a blue crystal with a yellow core. The gemstone is polished so that the culet (underside) of the stone in the yellow core and the crown (top) is in blue. This is a really spectacular stone.
At 9.0 on the Mohs hardness scale, sapphires are the second hardest natural mineral after diamonds. They fit well with all jewelry styles and are suitable for everyday use due to their hardness.
Sapphires look wonderful in engagement rings, right rings and pendants on the neck. Sapphires come in a variety of colors as well as in a variety of prices, from cheap to exclusive. Sapphire jewelry can therefore be combined with all kinds of outfits and occasions and fits in every class.
Sapphire is the original "True Blue" and the jewel of loyalty. In ancient times, the gift of a sapphire was a promise of trust, honesty, purity, and loyalty. This belief makes sapphire a preferred choice for engagement rings.
To maintain the brilliance and fire of a sapphire, it is important that you cleanse it regularly. The emphasis is on the regular cleaning. You can perform the cleaning with a mild detergent or soap and lukewarm water. You can gently scrub with a soft toothbrush.
It is also worthwhile to show that today artificial sapphires are produced in the laboratory. These artificial sapphires are similar in all respects to the naturally occurring sapphires, except that they do not have the defects and inclusions seen in the latter. They are also available in a much lower price range.
