yes, they are also the birthstone for the month may.
Diamonds, emeralds, saphires, peridot, and topaz are some crystal gems.
Emeralds are not actually rocks, but minerals of the beryl family that have gemstone qualities.
The element that gives emeralds their beautiful green color is the same element that turns corundum into red rubies. Red Rubies and emeralds are like twins but not the same color. ITS A CRYSTAL
Emeralds are naturally occurring gemstones, and are a Beryllium and Aluminium Silicate. Much of the green colour is due to a Chromium content. Natural emeralds commonly have inclusions or contaminants, so seldom is a good transparent crystal found. Man-made emeralds may be created, and these are usually as perfect a crystal as desired. They are the same material as the natural ones, but are not as well regarded by the jewellery trade.
Emeralds are a type of beryl gemstone, and they do not have a specific boiling point as they are not a liquid. When exposed to high temperatures, emeralds can be damaged or even shattered due to their internal structure and impurities. It is not recommended to heat emeralds as they are sensitive to temperature changes.
EMERALDS
A diamond is one form of carbon crystal. However many other substances form crystals under the right conditions. Sugar, salt and emeralds are all examples. So, a diamond is a crystal, but a crystal doesn't have to be a diamond.
Emeralds are made of beryl, a mineral species that consists of beryllium aluminum cyclosilicate. The green color of emeralds comes from trace amounts of chromium, vanadium, or iron in the crystal structure of beryl. The presence of these elements affects the color and quality of the emerald.
ionic crystal
Emeralds are not typically in liquid form, as they are a type of mineral. However, natural emeralds do not have a specific smell. If you encounter a liquid claiming to be made from emeralds, it likely contains added fragrances or chemicals.

A sim crystal of course! ^_^ It doesn't have a type, but it's called the plumbob.
