![]() Kyanite’s name draws from the Greek word for cyan, kyanos. It’s usually known as large, bladed crystals but it can also be found as small individual crystals of deep blue color. Its defining feature is that the hardness of the mineral varies depending on the angle you approach it compared to the angle of the crystal’s growth. Kyanite is one of the weirder minerals out there. Lapis is a lot more complex than it appears at first glance, but it’s well worth gaining knowledge about it. It’s been used in most types of artwork at one time or another and it continues to be used to this day, while still hailing from the regions where it was originally discovered. Lapis’ provenance and beauty have kept it in close association with humanity for a long time. The whole stone is complex, which leads to the rather stark contrast between crumbly, low-grade material and high-end lapis lazuli which is very solid and almost entirely the rich blue the material is known for. ![]() It’s a complex conglomerate of white calcite, combined with the ultramarine lazurite and flecks of pyrite in many cases. Lapis is actually a rock rather than a pure mineral. The stone mainly hails from the Middle East, with particularly high-grade deposits coming out of Afghanistan. It was highly prized among the ancient Egyptians as an inlay material, a precious stone in its own right, and even as a dye or paint. Lapis is the longest-running of them, being found in ancient artifacts that are millennia-old. Various uses such as healing, jewelry, dishes, show pieces, vases, etc.There are, perhaps, three ultra-famous blue stones. Hexagonal, cubic, orthorhombic, tetragonal, rhombohedral, and monoclinic Shape, atom composition, bonds and defectsĬhemical composition and their crystalline structure Refractive index, dispersion, specific gravity, hardness, cleavage, fracture, and luster Some come with mineral bases like diamonds or rubies and with organic bases like amberĬrystals are solids that have atoms, ions and molecules fixed in a regular order, which extend in three dimensions 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. ![]()
