Questions About Tanzanite A
  • 1stDibs ExpertApril 5, 2022
    A trillion tanzanite is a violet-blue gemstone that is considered the highest quality of tanzanite available. Named after Tanzania, the country in which it was discovered, tanzanite is also a popular gemstone because it's the American Gem Trade Association's official December birthstone. Shop a collection of tanzanite jewelry on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    Extremely high temperatures and dramatic, sudden temperature changes can damage tanzanite gemstones. In addition, strong acids like hydrochloric and hydrofluoric will eat away at the stone. Ultrasonic and steam cleaning devices are generally considered unsafe for tanzanite. On 1stDibs, shop a collection of tanzanite gemstone jewelry.
  • 1stDibs ExpertJune 30, 2023
    Yes, tanzanite can be faked. Some stones that might be substituted for tanzanite include cubic zirconia, synthetic spinels and yttrium aluminum garnets. Replicas may also feature colored glass. A certified appraiser or experienced jeweler can help you determine the authenticity of a stone. On 1stDibs, shop an assortment of tanzanite jewelry.
  • 1stDibs ExpertAugust 17, 2021
    The color of tanzanite that is most expensive is strong blue or intense purple-blue. Other colors are less rare and so not as valuable. Find a range of antique and vintage tanzanite jewelry on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    Tanzanite is much more rare than diamonds. Because diamond prices are more or less controlled, diamonds generally cost more, even though they're easier to find and mine than tanzanite.
  • 1stDibs ExpertFebruary 22, 2021
    Per carat triple A grade tanzanite can be worth between $425 and $480. Blue tanzanite is the most valuable color so vivid blue gems are worth more.
  • 1stDibs ExpertApril 5, 2022
    Tanzanite comes in a variety of sizes and cuts. Most tanzanite used in jewelry will not have inclusions visible to the human eye. The cut will also determine how the color of the gem displays, which can be different depending on the viewing direction. Carat weight will also play a role in the tanzanite’s quality. Browse a selection of tanzanite jewelry on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    Because tanzanite prices are controlled by supply and demand in a way that diamond prices are not, the price is more linked to rarity. As a result 1 carat of the finest grade tanzanite is worth $600 to $700, but lower quality stones can be less expensive.
  • 1stDibs ExpertSeptember 28, 2021
    The value of tanzanite per carat changes regularly. However, the value of A-grade tanzanite per carat in 2021 is about $200 for around 1.99 carats, $250 for around 2.99 carats, $275 for around 9.99 carats and $300 or more for anything above 10 carats. Shop for your first piece of tanzanite jewelry on 1stDibs today.
