![]() ![]() Other gemstones are semi-precious gemstones. However, in modern usage, only four gemstones belong to the category of precious stones they are diamonds, emeralds, sapphires, and rubies. In the west, gemstones are traditionally classified into two main categories: precious gemstones and semi-precious gemstones. Furthermore, there are a number of ways to create these stones. These look like small imperfections or spots within stones. They may also have traces of other minerals. Gemstones form below the surface of the earth. In fact, most people prefer gemstones with clear, intense, and saturated primary colors. They may look like ordinary rocks in their rough states, but one can observe color and luster after cutting and polishing. Most gemstones are hard to the touch and are available in a variety of colors and shades. Gemstones are stones or pieces of minerals that have been cut and polished and made into a piece of jewelry or accessory. Crystals also form when water evaporates from a mixture. Gemstones like diamonds, rubies, and emeralds form this way. Moreover, an example is the cooling of magma. This forms a uniform, repeating pattern, forming crystals. Some molecules in the liquid get together as they try to become stable. In nature, crystals usually form when liquids cool and start to harden. Moreover, salt (sodium chloride crystals), diamond (crystal carbon), quartz (silicon dioxide crystals), and snowflakes (water ice crystals) are some examples of crystals.Ĭrystallization is the method of formation of crystals. There are seven main crystal shapes: cubic, trigonal, triclinic, tetragonal, orthorhombic, hexagonal, and monoclinic. This repeating pattern makes the material form many unique shapes. – Comparison of Key Differences Key TermsĬrystals are a type of solids whose molecules fit together in a repeating pattern. Difference Between Crystals and Gemstones It’s important to remember that not all crystals are gemstones, but most gemstones are crystals. One thing that has to be noted is that different gems have different properties like different crystals having different properties.The main difference between crystals and gemstones is that gemstones are rare, high-quality minerals, but not all crystals are made of rare, high-quality minerals.Ĭrystals are a type of solids whose molecules fit together in a repeating pattern, while gemstones are stones or pieces of minerals that have been cut and polished and made into a piece of jewelry or accessory. When comparing the value of crystals and gems, the latter ones are priced more.ħ. Crystals are mainly classified as cubic, hexagonal, tetragonal, orthorhombic, monoclinic and rhombohedral.Ħ. Gems can be classified according to the chemical composition gemstone and the crystal structure. Gem is also known as gemstone that can be prescious or semi precious that is cut and polished to be used in jewelry.ĥ. Crystals are solids that have atoms, ions and molecules fixed in a regular order, which extend in three dimensions.Ĥ. Gems can be mineral based such as ruby or diamond and organic based such as amber.ģ. A gem can be a crystal whereas a crystal will not always be a gem.Ģ. The crystals also come in colours according to the transmission of light through them.ġ. When comparing the colour between gems and crystals, the gems come in various colours like red, green and blue. One thing that has to be noted is that different gems have different properties as different crystals having different properties. ![]() When comparing the hardness, specific gravity, refractive index, durability and fluorescence, the crystals are different from the gems. Almost everything related to minerals can be termed as crystals as they have specific properties. When comparing the value of crystals and gems, the latter ones are priced more. Crystals are mainly classified as cubic, hexagonal, tetragonal, orthorhombic, monoclinic and rhombohedral. The precious gems include diamond, sapphire, ruby and emerald and all other gems are considered to be semi-precious. Gem is also known as gemstone that can be prescious or semi precious that is cut and polished to be used in jewelry. Crystals can also be defined as objects that have well-defined geometric shapes. Gems can have mineral bases such as ruby or diamond and an organic base such as amber.Ĭrystals are solids that have atoms, ions and molecules fixed in a regular order, which extend in three dimensions. ![]() Crystals are pure substances that have molecules arranged in a regular geometric pattern.Ī gem can be a crystal whereas a crystal will not always be a gem. Gems are beautiful stones that are used in making jewelry. Gem is a rare mineral that is highly priced. ![]()
