Buying Tips for Tanzanite Bangles

  • Tanzanite is a Type I gemstone, meaning that it is generally eye flawless. Specimens with visible inclusions are significantly cheaper.
  • This lovey gemstone measures 6.5 to 7 out of 10 on the Mohs Scale of Hardness, which means it is not overly soft but also not extremely durable like diamonds and sapphires. When wearing tanzanite jewellery, take care against accidental knocks and scratches.
  • Do not clean tanzanite jewellery in an ultrasonic or steam cleaner-simply use a soft toothbrush and clean gently in warm soapy water.
  • Top quality, deeply saturated tanzanite gems are rated AAAA for their exceptional quality, but due to high demand and the fact that they're in limited supply, means they are becoming extremely rare.
  • Colour saturation defines the splendour of the stone's hue-as the depth of colour declines in a specimen, so does the rarity, quality and value of the gem.
  • Generally, tanzanite requires artificial heat treatment to 600 °C in a gemmological oven to bring out the unforgettable purple blue colour of the stone.
  • Tanzanite should not have any cracks or bubbles, as it they increase in size they could cause the gem to shatter.
  • Unlike many other gemstones, tanzanite goes well when set into most every type of metal, from gold and platinum to sterling silver, titanium and stainless steel. This makes it ideal for bangles.
  • If you're on a budget, it's wise to choose bangles that are thinner since the amount and type of metal used will obviously affect the cost. It's a good idea instead to buy yet buy a few thinner bangles for the charming tinkle that makes this type of jewellery popular.
  • When choosing a tanzanite bracelet as a gift for someone, consider their body size so that you get the correct wrist diameter.
  • Bracelets can often stretch, so choose a smaller, rather than larger size bracelet to avoid it accidentally slipping off.
  • The cut of any gemstone is important as it can make the gemstone appear larger. For example, a rectangular cut stone will appear larger than a round cut stone. A good cut is also critical to the brilliance and clarity of a stone, as well as helping to conceal inclusions (internal flaws).
