Due to its extreme rarity—combined with a geologically limited deposit—tanzanite is considered a particularly attractive asset. Experts expect that the scarcity of reserves will increase the value of high-quality tanzanites in the long term.

Since its discovery in 1967, the market for tanzanite has grown steadily. Larger, untreated specimens with intense color, in particular, have experienced significant increases in value on the international gemstone market.

Tanzanite is said to have inspiring and calming effects. It is said to promote creativity and provide emotional clarity. In gemology, tanzanite is recognized as the modern birthstone for the month of December .
