THE 7 CRYSTAL SYSTEMS AND THEIR GEMS
Gemstones are formed in single or multiple discrete crystals, in massive collections of microscopic crystals, or in amorphous masses. There are several classes of crystal structure based on the symmetry of the resulting crystals, and there are also non-crystalline minerals used as gem materials. Based on the crystal axes and the angles at which they intersect, crystals are divided into seven systems - Cubic, Tetragonal, hexagonal, trigonal, Orthorhombic, Monoclinic, and Triclinic. To better understand the structure, here’s a quick look at these seven crystal systems:- Tetragonal System In this, the three axes intersect at right angles. Two axes with the same length are positioned in the same plane. The main axis can be either longer or shorter, resulting in a triangular shape. Zircon is a gemstone that comes under this category. Due to the tetragonal structure, strength and durability, zircon is an ideal choice for spectacular, long-lasting jewelry . Hexagonal s...
