![]() ![]() When polished, the inclusions in pietersite exhibit chaotic chatoyancy whereas in tiger's eye, the inclusions are arranged in parallel lines and give the appearance of a continuous line.īuying Pietersite and Determining Pietersite Gemstone Value Back to Top Pietersite Color Crocidolite is the same material responsible for tiger's eye chatoyancy. Pietersite is characterized by its distinctive swirls or streaks of gold or orange, due to the crocidolite inclusions within a microcrystalline silica host. The term "pietersite" is now used as a general term to describe brecciated tiger's eye. Pietersite from Namibia was first described in 1962 by Sid Pieters, who named it in his father's honor. Pietersite is a rare dark-gray or reddish breccia aggregate (rock made up of fragments embedded in a matrix), comprised mostly of hawk's eye and tiger's eye. Remember to rinse well in order to remove all soapy residue from your precious Hawk’s Eye gemstone.ĭeposits of Hawk's Eye can be found in Thailand, the Northern Cape province of South Africa, Australia, Brazil, Canada, China, India, Korea, Myanmar (Burma), Namibia, Spain and in the United States (mostly Arizona and California).About Pietersite - History and Introduction Hawk's Eye is sensitive to some acids so avoid harsh chemicals like bleach, perfume or hairspray.Ĭlean your gemstone with warm water and mild soap and a soft cloth. Being a form of quartz, it is durable enough to be fashioned into any type of jewelry and can even be carved into charming floral cuts. Though Hawk's Eye is a rare gemstone, it remains affordable. Hawk's Eye is the astrological stone for those born under the zodiac sign of Sagittarius and is the planetary stone of Jupiter. It protects the wearer from the dangers on the road, and also from the negative energy of others. Hawk’s Eye in crystal healing is used for issues with the eyes, spine and neck. It enhances sight and vision and the ability to focus. ![]() It is said that Hawk's Eye helps to rid of phobia especially of flying. When Tiger’s Eye is mixed with red Jasper and Black Hematite and cut with its host rock intact, it is sold as Tiger’s Iron Matrix. When it is cut and polished in its host rock, it is sold as Tiger’s Eye Matrix. Tiger’s Eye is the most famous of the three related gemstones. Nonetheless, Hawk’s Eye for the most part is not treated or heated. Some darker redder stones are dyed or heated to improve the color nitric acid can also be used to lighten too dark colors. There are imitations of Hawk’s Eye which are made from artificial fiber-optic glass. Due to its hardness, Hawk’s Eye gemstones can also be fashioned into ovals, pears, rounds and freeform shapes. It is also carved as an ornamental stone. In order to maximize this effect, it is almost always cut en cabochon. This effect can be seen even in plain, flat-cut stones. The bird's eye effect in Hawk’s Eye occurs as small rays of light dazzling on and off the surface of the cut and polished gemstone. It is a brecciated aggregate form of Hawk’s Eye or Tiger’s Eye with a chaotic swirling pattern. Pietersite is composed of both Hawk’s Eye and Tiger’s Eye. ![]() Less traces of iron results in blue crocidolite color, and this is named Hawk’s Eye. When more traces of iron oxide is present, the color becomes brownish golden, it is then known as Tiger’s Eye. Hawk's Eye differs from Tiger's Eye by its distinct color. It is closely related to Tiger’s Eye and Pietersite, both of which also display the chatoyancy effect. It displays an iridescence that enhances its silky luster, more so when cut en cabochon. Hawk's Eye has a hardness ranging from 6.5 to 7 on the Mohs scale. Hawk’s Eye, same as Tiger’s Eye, is usually multicolored with wave patterns or golden stripes. It occurs in trigonal/hexagonal and fibrous aggregate crystal structure. Hawk's Eye is of a silicon dioxide chemical composition. It is desired for its chatoyancy which is a bird’s eye effect that looks provocatively similar to the eye of a hawk. Hawk’s Eye is also known as Blue Tiger’s Eye and Falcon’s Eye. This occurs when quartz becomes implanted between the fibers of crocidolite, and eventually replacing crocidolite completely yet at the same time retaining the fibrous shape of crocidolite. It is a pseudomorph that began as a crocidolite which is a fibrous blue mineral and later transformed into quartz. Hawk's eye is a blue-gray to blue-green microcrystalline variety of fibrous quartz. ![]()
