Gemstone Lexicon: Comprehensive Lexicon of Gemstones

Gemstone Lexicon

Gemstones throughout history

Gemstones or precious stones are extremely rare minerals that were formed at vast depths within the earth under high pressure and high temperatures. Archaeological finds from the Mesolithic period already document the interest with which gemstones have been regarded since the dawn of history. Gemstones have always been used as elements of jewellery and ornamentation. As status symbols, they were reserved for the wealthiest classes of society. Princes and kings were particularly fond of demonstrating their power by wielding insignia and regalia encrusted with precious stones. In earlier times gemstones were surrounded with mysterious and otherworldly lore and legends and frequently served as amulets and talismans. Even today, alternative medicine makes use of the power attested to gemstones by esoteric teachings.

What are gemstones?

There is no general umbrella definition for the term 'gemstone'. The majority of gemstones are minerals, and more rarely mineral aggregates, rocks or organic substances (such as amber). All these minerals have a unique and special beauty in common. Gemstones are extremely rare. Most of them are prized for the individual colours, iridescence and brilliance that make them unique. Many gemstones (particularly diamonds) have properties of extreme hardness or fascinating inclusions which transform them into something very special. There are several hundred different kinds of gemstone. The harder types (Mohs rating of 6 and upwards) are more suitable for cutting and polishing for jewellery. Often these processes are essential to reveal the beauty of the stones. Sometimes as much as 90% of an apparently inconspicuous rough gem must be cut away to create a gemstone with optimum light refraction and supreme brilliance.
