What are sapphires?
The sapphire is one of the most popular colored gemstones. The mineral has always been highly prized, considered a luxury item and widely used in the jewelry of European royal families since the Middle Ages.
Sapphire is a blue-colored corundum variety. Some people think that sapphires exist only in blue hues, but they come in a wide range of colors, including yellow, pink, purple, green and black. Sapphires that have a coloring other than blue are called «fancy».
The following article will tell you about this mineral, how sapphires prices are determined, what colors and varieties it comes in, and will also help you to figure out which type of sapphire is right for you.
The pricing of sapphire
The three main criteria that form the price of sapphires are color, clarity, and treatment.
1. Color. The richer the color, the more expensive the stone will be. The color difference can alter the cost of a stone by 4 times.
2. Clarity. The fewer the cracks and inclusions, the better the clarity of the stone and the more expensive it will be.
3. Treatment. As a result of heating some of the external properties may be improved. The color of a stone becomes richer. Heating can melt certain inclusions and improve the clarity. The price of an unheated sapphire can be twice as high as that of a similar quality sapphire that has been treated. In other words, unheated minerals are valued the most.
However, these three criteria are not the only ones that form the value. The origin of a stone can also influence the price. If the sapphire is from Kashmir, it will increase its value, while its Thai origin will make it much cheaper.
Also, one of the most important thing in the trade is the certificate of the stone. The cost of the certificate depends on the laboratory.
Certificates from GRS, Gia, Gubelin and SSEF laboratories are the best (read more about certificates in this article link). This is why some sapphires will cost $8000 per carat and some $200 per carat.
Varieties of sapphire
Of all the corundum varieties, blue is the most desirable. There are two main expensive colors in the commercial classification: «Royal Blue» (rich dark blue) and «Cornflower Blue».
«Royal blue» has one of the highest grades for a sapphire color, coming in the Vivid blue and Deep blue categories.
«Cornflower Blue» is named because it resembles the blue color of the German national cornflower, which is part of the «Vivid blue» and «Intense blue» categories.
The most beautiful classic blue sapphires are mined in Kashmir, northern India.
The word "padparascha" was used among the ancient people of Sri Lanka and means "the color of the red lotus." This is an extremely rare variety of sapphires, which is an unusual mixture of pink and orange. These stones usually cost more than other varieties of sapphires.
Pink and Purple Sapphires
Pink and purple sapphires are truly unique. The trade name «pink sapphire» refers to a wide color palette, ranging from light pink to purple-pink tones. The price of pink-colored sapphires goes up as their brightness increases, which is a common feature of all fancy sapphires. The best specimens are mined in Sri Lanka and Madagascar.
Yellow to Orange Sapphires
Yellow sapphire is one of the most popular transparent noble corundum varieties. The color palette is limited to golden hues: from light, pastel yellowish to rich yellow-orange. The most expensive and valuable shade is Golden.
Orange sapphires range from yellowish-orange to reddish-orange. The best orange sapphires have a rich, pure orange or red-orange color, and vivid saturation.
Color Change Sapphires
Color-changing sapphires are chameleon stones that change color under different lighting . The color change of this gem is caused by impurity elements in its chemical composition. Under daylight equivalent light the mineral is perceived as greenish or blue. Reddish, purplish and pinkish hues emerge under incandescent light.
A star sapphire is a rare type of sapphire. It is unique for its phenomenon called asterism, which appears when the star-like rays intersect across the faces. The star effect is caused by the reflection from tiny, needle-like inclusions that are oriented in several specific directions.
