Questions About 20 Carat Tanzanite
  • 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.
  • 1stDibs ExpertApril 5, 2022
    The term “20 carat gold” does not have a meaning. “Carat” is a unit of measurement used to describe the size of gemstones. “Karat” is the unit used to describe gold precious metal. Gold stamped as 20 karat or 20K is 83.3 percent pure gold and 16.7 percent metal alloy. You'll find a wide variety of gemstone jewelry on 1stDibs.
