Water energy is provided by deep blue tanzanite colored crystals, which offers calm, tranquil power, and vitality. It also removes negative, stagnant energy. Tanzanite in violet or purple-blue delivers fiery energy into an area or house. This tanzanite color exudes brightness, zeal, brilliance, and warmth. It is most common in Madagascar.
The name comes from the region where it is found naturally: Tanzania. The word tanzanite comes from the Kikuyu language and means "crystal of the sky."
There are several varieties of blue zebra stones, but only one variety is called blue tanzanite. It is said that the color changes depending on how it is treated after it is mined. Blue tanzanite can be blue, green, or grayish blue and it tends to be more vivid than its counterpart, black zebra stone. It can also appear white or yellow under certain conditions. However, these changes don't affect its value as a gemstone.
Blue tanzanite is rare because it is difficult to extract from the earth. Also, since it needs very clear water to grow, it's likely to occur near volcanic vents or underground springs.
Some sources say that blue tanzanite is more valuable than black zebra stone because it can cost up to $20,000 per carat ($40,000 per kilo). Others claim that there is no difference between them.
Tanzanite may have an extremely vivid, strong blue hue. The hue of excellent tanzanites is a vivid violetish blue with red bursts of pleochroic color emanating from within the stone. Because of the gem's high pleochroism, fashioned samples often display a combination of blue and violet hues in a variety of tones. Tanzanite can also appear brown, black, or white.
The name "tanzanite" comes from the region where they are found: Tanzania. These gems are valuable because they contain several rare elements that make them hard to replace. Also, due to their intense colors, tanzanites are popular among jewelers who use them as substrates for colored engravings.
There are two types of tanzanite: micro-CTZ and macro-CTZ. Micro-CTZ tanzanites have internal structures that can be seen under magnification while macro-CTZ stones have visible pores on the surface. Both types of stones are highly pleochroic, which means that they will display different colors depending on how they are lit. Pairs of macro-CTZ stones from the same source usually have different levels of pleochroism; one may be more blue-green than the other. They can be difficult to distinguish when they are mixed together in a collection.
Micro-CTZ tanzanites tend to be smaller (usually less than 2 cm) with a higher price tag ($20,000 and up).
Tanzanite is known for its very high trichroism, which causes it to appear alternatively blue, violet, and burgundy depending on crystal orientation. Tanzanite can also appear differently in different lighting situations. It is believed that the name "tanzanite" comes from a place near where it was discovered - Tanzania.
Tanzanite is one of only a few gemstones that changes color when illuminated by ultraviolet light (blacklight). This gives it use as an identification tool for works of art where other means of determination are required. The presence of fluorescent molecules inside the stone with unique spectral properties of their own allows scientists to identify the origin of the stone through fluorescence spectroscopy.
Tanzanite is one of the most valuable gemstones in the world. The rarity of good stones and the cost of cleaning processes mean that production doesn't come close to meeting demand. There are only three major sources of tanzanite: India, USA, and Russia. The best stones are considered sacred by some tribes who inhabit the region where they are found. These stones are not traded, instead they are kept within these communities.
There are more than 100 varieties of quartz but only a few of them are useful as gems. Tanzanite is derived from a type of quartz that contains small amounts of chromium oxide.
Tanzanite Gemstones AAA This grade of gem will always be of the best quality, with saturation of deep blue and vivid violet. The name comes from the region where it is found in Tanzania.
The color of tanzanite is due to impurities that can't be removed through washing or refining. Although it's rare, some samples have been found to be almost white or pale greenish-blue.
There are two types of tanzanite: purple and blue. Purples contain more red than blue, while blues are more blue than red. Both types have similar physical properties including hardness, weight, and dispersivity. The difference between the two is only visual, so they can be used interchangeably when talking about jewelry made from them.
Tanzanite was first discovered in 1872 near Lake Victoria in Tanzania. It's often compared to alexandrite because of their similar colors and patterns but with tanzanite you get more blue. The gems tend to be smaller for their type with averages being around 1 cm (0.4 inches) across. They also have a slightly shorter lifespan; usually less than 100 years.
Tanzanite is very expensive because there is only one mine in existence that produces any amount of gems worth mining.
