  • 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.
