The Fiery Red Ruby - By Far The Most Expensive Gem of All
The very finest, top quality ruby can be so rare which it may be our planet's most valued gemstone for hundreds of years. Actually, to this day, flawless good quality rubies tend to be more valuable and rare than good quality colorless diamonds. A 16 carat ruby sold at auction for US$227,301 per carat at Sotheby's in 1988. A 27.37 carat Burmese ruby ring sold for US$4 million at Sotheby's in Geneva in May 1995, or $146,145 per carat. A 32 carat ruby sold for US$144,000 per carat at Sotheby's in 1989. In comparison, eight D-color internally flawless diamonds 50 plus carats were purchased from yesteryear 10 years along with the largest, a pear-shape of 102 carats, fetched a mere US$125,000 per carat. Top rubies are really rare perhaps the world's top gem dealers must incessantly comb through wealthy estate sales and auctions to get them. Clean bright stones in sizes above five carats are particularly rare.
Ruby may be the gem quality form of the mineral corundum, and something of the very durable minerals which exists, a crystalline kind of aluminum oxide. Corundum includes a hardness of 9 on the Mohs scale and it is quite challenging. In the common form, corundum is even used as an abrasive. Colors of Corundum besides red these are known as Sapphire. The element Chromium is in charge of the red color with this gem, but too much Chromium can certainly turn corundum emerald green coloured. Heat therapy is quite typical in ruby gemstones (as is also true for those kinds of corundum) and it is employed to dissolve "silk" inclusions, which ends up in a much more transparent, more intensely colored stone. The heat therapy is considered permanent and will not usually detract from value of the stone.
The best source of fine rubies is Burma, that's now called Myanmar. The ruby mines of Myanmar are older than history: stone age and bronze age mining tools have been found within the mining section of Mogok. Rubies from the legendary mines in Mogok often have a pure beautiful red colors, and this can be referred to as "pigeon's-blood" although that term is a lot more fanciful than an actual practical standard inside the trade today. Myanmar also produces intense pinkish red rubies that happen to be also vivid and intensely beautiful. Many of the rubies from Burma have a strong fluorescence when encountered with ultraviolet rays like those invoved with sunlight, which layers on extra color. Burma rubies have a very reputation of holding their vivid color under all lighting conditions.
Fine rubies will also be found in Thailand. Thai rubies tend to be darker red in tone: a genuine red, tending toward burgundy instead of pink, as Burma rubies do. This will make them popular in america where consumers generally prefer their rubies becoming a darker red as opposed to a darker pink. Some Thai rubies have black reflections, a phenomenon called extinction, that will make their color look darker laptop or computer actually is. But Thai rubies may also have a rich vivid red that rivals the Burmese in intensity. Sri Lankan rubies may also be very beautiful. Many Sri Lankan stones will often be pinkish in hue and many are pastel in tone. Some, however, resemble the vivid pinkish red hues from Burma.
Rubies from Kenya and Tanzania surprised the world once they were found within the sixties because their color rivals the world's best. Unfortunately, most of the ruby production readily available countries has several inclusions, tiny flaws which diminish transparency. Rubies from your African mines are rarely transparent enough to facet. However, their fantastic color is displayed to full advantage when cut cabochon style. Several rare clean stones have been seen which can be high quality.
The key element in value of a ruby is color. The top qualities are as red obviously: a saturated pure spectral hue without the overtones of brown or blue. A powerful pure, red colorization, uniform color is easily the most valuable gem. Clarity is also of secondary importance, but a fine colored gem with slight flaws remains to be highly valued. Large sizes rubies tend to be rare than diamond as well as a price of fine gem ruby increases significantly (much more than other gems) with additional weight.
The term red comes from the Latin for ruby, ruber, that is produced by similar words in Persian, Hebrew, and Sanskrit. The power of color of an excellent ruby looks like a glowing coal, by far the most intensely colored substance our ancestors ever saw. It is no surprise they ascribed magical powers to the telltale fires that burned perpetually rather than extinguished themselves.
After color, one other factors which influence the need for a ruby are clarity, cut, and size. Rubies which can be perfectly transparent, with no tiny flaws, will be more valuable than those with inclusions that happen to be visible on the eye. Cut can produce a huge difference in how attractive and lively a ruby generally seems to the eye. A well-cut stone should reflect back light evenly across the surface without a dark or washed-out area within the center that will be a consequence of a stone which is too deep or shallow. The design ought to be symmetrical and there shouldn't be any nicks or scratches in the polish.
Ruby sometimes displays a three-ray, six-point star. These star rubies are decline in an effortless domed cabochon cut to display the effects. The star is better visible when illuminated which has a single light source: it moves through the stone as the light moves. This effect, called asterism, is caused by light reflecting off tiny rutile needles, called "silk," that happen to be oriented across the crystal faces. The price of star rubies and sapphires are influenced by a couple of things: the intensity and fantastic thing about one's body color along with the strength and sharpness in the star. All six legs needs to be straight and equally prominent. Star rubies rarely possess the mixture of an excellent translucent or transparent color as well as a sharp prominent star. These gems are valuable and expensive.
