Aracaria Crystal & Gemstone Guide

Aracaria Crystal & Gemstone Guide by Stefan Mager explores the fascinating world of GEMSTONES and CRYSTALS, which are pieces of minerals divided into precious and semi-precious stones. Broadly speaking, diamond, ruby, sapphire, and emerald are considered 'precious', while all others are semi-precious.

Gemologists identify stones by their chemical composition, their crystal structure, and their habit, which refers to the location where the stone is usually found. Gemstones are also classified into groups, types, and varieties, with further classifications including light properties, hardness, fracture, colour, and lustre. Material or flaws within a stone are called inclusions.

The value of gemstones varies and can fluctuate greatly. Gemstones are often artificially treated to enhance their colour or clarity. Synthetic gemstones, created in controlled laboratory conditions, can be physically, optically, and chemically identical to natural stones, though their colours tend to be more vivid and are devoid of impurities.

Different cultures have developed traditions of crystal healing. Healers believe in the esoteric powers of gemstones, selecting stones by colour and their metaphysical qualities. Wearing a gemstone as an amulet may be beneficial to physical and mental well-being.

This Guide presents 72 gemstones and includes both their physical and esoteric characteristics.
