Gemstone Rarity vs. Gemstone Value

Not all rare stones are expensive, and not all costly rocks are rare. Still, gemstone rarity often increases gemstone value.

Precious Gemstones vs. Semi-Precious Gemstones

Traditionally, only four are considered "precious":

Diamond
Ruby
Sapphire
Emerald

However, Alexandrite and tanzanite—though classified as semi-precious—are rarer than some precious stones.
