Precious Vs. Semiprecious Stones

2 years ago 965 Views

In the mid-1800s, stones became classified into two groups: precious and semiprecious. The term “precious stone” refers to four types of gemstones: diamonds, rubies, sapphires, and emeralds. Semiprecious stones are all other gemstones that are used in personal adornment. Some examples are: amethyst, aquamarine, chrysocolla, lapis lazuli, malachite, peridot, tiger's eye, tanzanite, and turquoise. Even pearls, amber and coral are included in this category.
