Precious stones and semi-precious stones – Names and meaning

We could also name them as precious and semi-precious gems; the two terminologies are valid.

As we know, the human being, since its inception, has always been devoted and endowed with a certain mysticism to precious stones or foreign stones or very difficult to find in nature, conferring different uses: for ornamentation, as symbol of power and exclusivity associated with the worship of certain deities and even using them to heal or to the contrary.

Gemstones and semi-precious stones are almost mostly minerals; some of them, however, are organic (such as amber, fossilized plant resin).


To distinguish between precious stones and semiprecious stones are used three factors:

  1. The hardness scale them (which ensures its durability), which also traditionally coincides with stones or precious gems for excellence (the hardest gemstone diamond there is, as we have seen in previous articles).
  2. The rarity, scarcity or difficult to find in nature.
  3. Its beauty and perfection. When we speak of the beauty and perfection of a stone, either precious or semiprecious, we refer to the color, brightness, transparency and purity. A gemstone pure, flawless and radiant color can have a value even higher than a diamond of similar characteristics.

The only three stones or precious gems besides the diamond-considered by the above factors are the ruby, the emerald and sapphire blue.
