![]() ![]() ![]() Composition differs according to type of mineral. Rare minerals that are found on the earth. Can be a crystalĪ crystal is a solid material whose constituent atoms, molecules, or ions are arranged in an ordered pattern extending in all three spatial dimensions. Salt and snowflakes are the most common types of crystals that are encountered.Ī gemstone or gem is a piece of mineral, which is cut and polished and used to make jewelry or other decorations. Crystals are less expensive compared to gemstones. The color of crystal is determined by the light passing through it. Crystals are light in color and are mostly translucent. ![]() Crystals are classified as Hexagonal, cubic, orthorhombic, tetragonal, rhombohedral, and monoclinic shapes. Crystal symmetry requires that the unit cells stack perfectly with no gaps. Not all crystals need to be in solid formation, where water freezing also begins with small ice crystals that grow. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The price of the gemstones depends on the rarity, color, composition, hardness and cut.Ĭrystals are pure substances whose atoms, molecules, or ions are arranged in an ordered pattern, where they extend in all three spatial dimensions. Today, geologists use the chemical composition of a gemstone to classify it into groups, species and varieties. Gems can also come with mineral bases like diamonds or rubies and with organic bases like amber. Gemstones are classified by their color, translucency and hardness. Precious stones include diamonds, emerald, ruby and sapphire, while the rest are qualified as semi-precious stones. A gemstone can also be known as precious or semi-precious stones. Not all gems are minerals, such as lapis lazuli, a rock, and amber or jet, which are organic materials. Gemstones are rare pieces of minerals that are found in the ground, which are then cut and polished to be used in jewelry and other decorative pieces. A gem can be a crystal, while a crystal cannot be called as a gem. While gemstones are primarily used in jewelry and decoration pieces, crystals can be used in various applications such as healing, jewelry, vases, scientific purposes, etc. Gemstone and Crystals are both used in various applications in today’s world. Crystals are pure substances whose atoms, molecules, or ions are arranged in an ordered pattern, where they extend in all three spatial dimensions. Key Difference: Gemstones are rare pieces of minerals that are found in the ground, which are then cut and polished to be used in jewelry and other decorative pieces. ![]()
