Difference between gem and semi precious stones

In all natural gems, it can be subdivided into precious gems and semi-precious stones. Precious gems mainly include: diamonds, rubies, sapphires and emeralds. In terms of price, these gems are definitely valued by carat weight, so most of the time the gems mentioned refer to them.

General semi-precious stones: amethyst, citrine, topaz, tourmaline, aquamarine, garnet, peridot, obsidian morganite, tanzanite, zircon, lapis lazuli, prehnite, moonstone, coral, opal , Colorful, apatite.

The semi-precious stones can be specifically divided into: quartz gems and non-quartz gems. Among the quartz gems, crystal is the most important and the most diverse gem. The rest include tourmaline, aquamarine, peridot, amethyst, garnet, agate, etc.; non-quartz gems include amber and coral.

It should be noted that, the general classification principle is mainly based on the hardness and price of gemstones. That is to say, the more precious the gemstones are, the higher the hardness and rarer the gemstones are. However, in fact, many precious semi precious stones are also priced according to carat, such as tourmaline, hair crystal, ghost crystal, etc., so it depends on the actual situation. You should know that because gemstones are pure natural products, absolutely the same gemstones do not exist. There are always rules of heaven and earth.

According to the principle of hardness, the more precious a gem is, the higher its hardness is.

According to scientific research, natural stones with hardness above 9 can be classified as gemstones, which is one of the most important reasons why diamonds become the king of gemstones.

The hardness of semi precious stones is usually not high.

And many semi precious stones are fragile and easy to fall off in our daily life.

The price of precious stones is different.
