Sapphire (Corundum) Gemstones Source : Australia, Madagascar, Myanmar, Sri Lanka, Tanzania, Thailand, USA Birthstone : September (Alternate: Lapis) The name "sapphire" (saphir French or German, zafir Spanish, zaffiro Italian) was originally derived from Greek "sappheiros," as well as the Sanskrit Kuruvinda "sanipruja" meaning "hard stone," and the Hebrew word "sappir" meaning "gem." The biblical "Acts of the Apostles" referred to Sapphira, a woman who was executed for lying to the Holy Ghost. Sapphire (Corundum) Composition Sapphire belongs to the same "aluminium oxide" (alumina) mineral family (corundum) as ruby, but sapphire is far more abundant due to the larger occurrence of its chromium, iron, and titanium coloring agents. Sapphire colors range from canary yellow to blue, brown, gray, green, orange, pink, purple, and colorless. Sapphire corundum has no cleavage planes, but does have a conchoidal fracture, and can be parted more easily in certain directions. Corundum's crystal habit forms into six-sided barrel-shaped crystals that taper into pyramid terminations (diagram, below). Sapphire Inclusions Most sapphires contain inclusions which are visible to the naked eye or under low under magnification. These inclusions may appear as clouds, feathers, veils (below, left), silk fibers, or rutile needles, and may resemble an internal fingerprint impression in clearer stones. Sapphire Veil Inclusion - 330 carat 'Star of Asia' Sapphire Star Sapphire (Asterism) Certain varieties of sapphire can exhibit a six-pointed "star" or "asteriated" effect (above, right) from light reflections bouncing off of microscopic needle-shaped rutile crystals (also referred to in the ruby trade as "silk") which intersect at 60¡ angles. Star sapphires are semi-transparent to opaque, and the star effect is more apparent when a cabochon cut is used for the stone.

The GIA specifies thirty-one individual gemstone hues. Relating to sapphire, terms such as "blue," "slightly greenish blue," "very slightly greenish blue" are used to describe color tendencies. The color-grading nomenclature also specifies six levels of saturation ranging from "grayish" (neutral grey) to "moderately strong" to "vivid," and nine levels of tone ranging from "very light" to "very dark." A numerical value is assigned to each label for use in a gemstone color grading report. The most desirable blue sapphire color is an intense, pure, and primary blue with a slight hint of violet and very little of the gray or green color components. For a blue sapphire to receive a perfect '10' quality rating it would have a "violetish/blue" hue, with a 6 or "medium dark" tone, and 6 or "vivid" color saturation level. Specific color grades of blue sapphire are commonly refers to as: Ceylon Blue, Cornflower Blue, Electric Blue, Kashmir Blue, Royal Blue, Sky Blue, Velvet Blue, and Violet Blue. High-quality Kashmir, velvet-blue and Cornflower-blue sapphires will maintain their color and intensity under a variety of lighting conditions from bright sunlight to dim artificial light. Color Zoning in Sapphire Most sapphire will exhibit moderate to strong color-zoning, caused by growth layers as the crystal is formed, however, sapphire from Burma may have very uniform color with little or no color zoning. Sapphire color-zoning may appear as concentric hexagonal rings (below, left), that run parallel to the prismatic outer facets of the rough crystal. Skilled gem-cutters will insure that the faceted stone has some color in the culet to enhance the color when viewed through the table and crown. From the side however, these stones will have little color. Sapphire Mining The world's oldest sapphire mines are situated in Ceylon (Sri Lanka), and Kashmir (India and Pakistan). Sapphire deposits typically occur within metamorphic rock and pegmatite occurrences, or in gem-bearing, or "gemmiferous" gravels that are found along river-beds and ancient alluvial secondary deposits. These river gravels may also contain ruby, spinel, quartz, and zircon. Mining is typically a non-mechanized small scale operation involving several workers who dig a small pit around four feet deep, excavating the gravels with woven baskets. The material is then washed (sifted) using a circular woven sieve made of thin strips of bamboo. Kashmir Sapphire Historically, the finest sapphire in the world had originated from India's northwestern region of Kashmir, along the Pakistani/Indian boarder in the western Himalayas. The Kashmir region was famous for its blue sapphires which exhibited an intense, vivid blue hue that came to be known as "Kashmir blue" The 422.99 carat 'Logan Sapphire' from Sri Lanka - The Hall Sapphire Necklace by Harry Winston The Kashmir region's sapphire deposits were mined extensively during a brief decade-long period in the late 1800's, after a earthquake-induced landslide unearthed a large deposit, but the region was fully depleted by the early 1900's, and Kashmir is no longer a significant source for sapphire. This fact adds significant value to any stone that is positively identified as a true Kashmir sapphire. Thai & Burmese Mogok Sapphire Second only to Kashmir in quality and mystique, some of the world's most valuable sapphire, ruby and spinel has been found within the Mogok Stone Tract situated along the high-altitude Mogok Valley, about 175 km northeast of Mandalay, in Myanmar (Burma). The name "Mogok" is derived from the Burmese term "bamar moegokesetwaing" or "horizon." Within the 4,800 square-kilometer area that comprises the Mogok Valley, there are over 1,000 ruby and sapphire mines. In 1972 the world's largest sapphire, at 63,000 carats, was found in Mogkok. Thai Sapphire Market Burmese sapphire mining operations are conducted by state-owned mining enterprises such as Myanmar Gems Enterprise (MGE) and Myanmar Economic Holdings (MEH). During the early 1990s, the Thai border town of Mae Sai was the main transit-point for illegally smuggled Mogkok sapphires and rubies, but by 1995 the Myanmar government had slowed down smuggling operations, and Burmese sapphire is now in scarce supply. Rough Alluvial Sapphire - Myanmar Sapphire Mine. Myanmar's former capital city of Yangon (Rangoon) is now the officially sanctioned gem-trading capital within Myanmar. Notable ruby and sapphire mines within Burma are MGE's Yadana Kadeikada, Linyaung Chi, and Shwe Pyi Aye gem mines, all near Kyaukpyattha Village in central Mogok. Sapphire mining within Thailand occurs primarily within the Chanthaburi and Trat provinces, located in the southeastern part of the country bordering Cambodia, and near the northern boarder with Myanmar in the province of Kanchanaburi. Chanthaburi is known for its prized yellow sapphire called "Mekong Whisky," which has a golden brownish-yellow to orange hue. Sapphire Mining in Sri Lanka Sapphire from Sri Lanka (Ceylon) has supplemented the declining supply emanating from Myanmar and Thailand in recent decades. Sri Lanka is known for producing the highest quantity of larger, 100+ carat stones in the world. Yellow sapphire from Sri Lanka is called "pushparaga" in Singhalese ("pukhraj" in Hindi), and can be comparable in value to the finest Mogok sapphire. Pushparaga, also known as "Oriental topaz" or "hyacinth" has a golden or honey yellow color with brownish secondary hues that resembles actual topaz (pushkaraj). 115k Yellow Ceylon 'Pushparaga' Sapphire - Zoom - Bubblegum-Pink & Hot-Pink Ceylon Sapphire There is also a very rare orange-pink or red-orange Sri Lankan variety called "padparadscha sapphire" which can be as valuable as diamond. The principle mining area of Sri Lanka is situated around Ratnapura ("City of Gems") 60 miles southeast of Colombo. Ceylon yellow sapphires display a pure canary-yellow, brownish-yellow compared to other varieties of yellow sapphire which can have greenish overtones. Australian Sapphire The Central Highlands and Gemfields regions of Queensland, Australia have also produced some of the finer specimens of greenish-yellow, golden, green, orange, and blue sapphire, as well as the unusual "parti-colored," or multi-colored sapphires which are marbled with hues of blue, green and yellow. Australian 'Parti' Sapphire from Queensland - Zoom: Rutile Needle Inclusion in Sapphire Australia's largest sapphire mines are the underground Bedford Hill, Normans Hill and Scrub Lead mines, located in Rubyvale Township, Gemfields. In Australia, freelance prospecting, called "fossicking," is a popular vocation, and each year in early August, Fossickers from around Queensland attend the Festival of Gems "Gemfest" which celebrates the region's mining heritage. Sapphire Mining in Madagascar & Tanzania With the decline in production of Burmese and Thai sapphire, southeastern Africa and the island of Madagascar have become major new sources for sapphire within the last 40 years. Madagascar sapphire is found in the Andranondambo and Ilakaka mining regions in the southern part of the island. Rough sapphire from Androy, Madagascar - Bracelet showing sapphire color range A unique reddish-pink to mandarin-orange sapphire was discovered in Tanzania's Umba Valley during the 1960s. This variety was found in the Gerevi Hills and Lelatema Mountains north of the Umba River, in the Arusha Region of Tanzania. The Tundouro mine in Tanzania also produces a yellow sapphire with a distinctive greenish-yellow color.
