Care | Somewhat softer than quartz, tanzanite may be safely mounted in any form of jewelry, but when it is set in rings, gentle wear is recommended. Tanzanite should never be subjected to high heat such as that from a jeweler's torch. The best way to clean tanzanite is with warm soapy water and a soft cloth. |
Color | Tanzanites
are typically blue or violet-blue, but they can also be rare greenish
and greenish-blue shades. Tanzanite is a highly pleochroic gem, meaning
it can appear blue from one angle and violet or violetish-blue from
another. Vanadium is the main coloring agent required to produce the
rich blue-violet colors that are so highly prized in tanzanite.

Value | Tanzanite's color may be manipulated by cutting the crystal on one of two axes. Bluer stones are cut on the shorter axis and generally do not provide as high a yield. Consequently, intense blue tanzanite is more rare and costs slightly more than violet-blue tanzanite. |
Discovery![]() HistoryTiffany & Co. introduced tanzanite to the world in the late 1960s. Having one of the most famous jewelry companies in the world recognize tanzanite's potential was definitely serendipitous. But because the supply was not stable, the marketing and promotion of tanzanite came to a halt, sending tanzanite back into obscurity.Recognizing the potential for tanzanite, the Tanzanian government intervened in 1971 and attempted to bring tanzanite back to popularity. The mining and control of tanzanite was turned over to the state around 1976. Production decreased dramatically, taking with it what little market share tanzanite had regained. By the 1980s, conditions had not improved, production was irregular at best, and thousands of illegal miners had saturated the Merelani Hills. The government again took control of the area in 1991 and issued licenses to mine, mostly to native Tanzanians. Soon a temporarily sufficient tanzanite supply came to the market, allowing for tanzanite's tremendous growth. Read more. | ||

![]() Tanzanite is found in what geologists call "boudins," or sausage-shaped formations. Not every boudin will produce tanzanite, and many that do contain low-grade material that is not useful for jewelry. These boudins make straight, horizontal shafts within the earth that are impractical for mining. A bi-product of tanzanite mining is another very beautiful gemstone called tsavorite, a form of grossular garnet. As more tsavorite is found, the likelihood of finding jewelry-grade tanzanite lessens. Rhodolite and kyanite are also associated with tanzanite formations. |
Toronto
police have obtained a video that appears to show Mayor Rob Ford
smoking a crack pipe, a video Ford had said did not exist and that has
been at the core of a scandal that has embarrassed and gripped Canada
for months. Police Chief Bill Blair said on Thursday that the video, recovered after being deleted from a computer hard drive, did not provide grounds to press charges. Speaking outside the door to his office, Ford, a populist mayor who has repeatedly made headlines for his odd behaviour, said he has "no reason to resign". Toronto police discovered the video while conducting a huge surveillance operation into a friend and sometimes driver suspected of providing Ford with drugs.
Ford maintained he does not smoke the drug and that the video does not exist. He was elected mayor three years ago on a wave of discontent simmering in the city's outlying suburbs. Since then he has survived an attempt to remove him from office on conflict-of-interest charges and has appeared in the news for various scandals. Previous controversies include being asked to leave an event for wounded war vets because he appeared intoxicated, according to the Toronto Star, and making rude gestures at Torontonians from his car. He was forced to admit he was busted for marijuana possession in Florida in 1999, after repeated denials. Through it all, the mayor has repeatedly refused to resign and pledged to run for re-election next year. But the pressure ramped up on Thursday with all four major dailies in the city calling on Ford to resign. Cheri DiNovo, a member of Ontario's parliament, tweeted, "Ford video nothing to celebrate Addiction is illness. Mayor please step down and get help". 'Traumatic issue' On Thursday, Blair said the video of the mayor "depicts images that are consistent with those previously reported in the press". "As a citizen of Toronto I'm disappointed," Blair said. "This is a traumatic issue for citizens of this city and the reputation of this city." Blair said the video will come out when Ford's associate and occasional driver, Alexander Lisi, goes to trial on drug charges. Lisi now also faces extortion charges for trying to retrieve the recording from an unidentified person. Blair did not say who owned the computer containing the video. Blair said authorities believed the video is linked to a home in Toronto, referred to by a confidential informant as a "crack house" in court documents in Lisi's drug case. The prosecutor in the Lisi case released documents on Thursday showing they had rummaged through Ford's garbage in search of evidence of drug use. They show that they conducted a massive surveillance operation monitoring the mayor and Lisi following drug use allegations. Toronto Councillor Joe Mihevc said he continues to be shocked by the "depth and revelations that are coming out". "The mayor has to come clean and do it as soon as possible," Mihevc said. "He needs to talk honestly about his use of illicit drugs." |

Kenyan warplanes bomb al-Shabab camp |

The Kenyan military has said its warplanes bombed
targets held by al-Qaeda-linked armed group al-Shabab in Somalia, in
retaliation for an attack on a Nairobi mall that killed at least 67
people. The Kenya Defence Forces said on Thursday that they had destroyed a training camp used by the members of the al-Shabab group who attacked the Westgate Mall on September 21. "This was part of a broader mission by the AMISOM [the UN-backed African peacekeeping mission in Somalia], targeting where the Shabab were training," Colonel Cyrus Oguna, a spokesman for the Kenyan military, told Reuters. “Those attackers at the Westgate did their training there. We have been monitoring this particular area over a period of time, and we moved in when we got the green light." The camp had more than 300 fighters, many of whom are believed to have been killed or injured, the KDF said in a statement. Oguna said raids on the rebel strongholds would be sustained. Kenya's military said the "major aerial offensive" in the Dinsoor region completely destroyed the training camp at Hurguun and at least four "technicals" - improvised fighting vehicles - and a weapons store. Two leading members of al-Shabab were killed on Monday in a Kenyan drone strike. However, al-Shabab denied there had been any attack. "We do not know where they [Kenyan army] are getting that from. No attack happened in our area. Not in Dinsoor, not anywhere else," an al-Shabab spokesman told Al Jazeera, adding that the group's fighters had attacked Badhaadhe and Kismayo in the Jubba regions in the south. Meanwhile, a top UN official has said that the war against al-Shabab fighters in Somalia has “ground to a halt” and needed a surge of almost 4,400 more African Union troops and massive UN assistance to break the stalemate and avoid failure. Deputy Secretary-General Jan Eliasson told the Security Council on Wednesday that the UN-endorsed African Union force now in Somalia, and the Somali military, lack “the capacity to push beyond areas already recovered” from al-Shabab in the last 18 months. |
