Historical Origins and Etymology

The term "onyx" originates from the Ancient Greek word "onyx," meaning "fingernail" or "claw." This fascinating naming convention stems from the stone's resemblance to human fingernails in its lighter variations. Historical records trace onyx back to ancient civilizations, with significant mentions in Egyptian, Greek, and Roman cultures.

First Historical Mentions

Archaeological evidence suggests that onyx was first utilized around 4,000 BCE in ancient Mesopotamia. Carved seals, decorative objects, and jewelry from this period demonstrate the stone's early importance in human artistic expression.

Geological Formation: Nature's Intricate Process

Onyx forms through complex geological processes involving silica-rich solutions depositing in layers within rock cavities. Typically, these formations occur in areas with significant volcanic activity, where mineral-rich waters slowly crystallize and create the stone's distinctive banded patterns.

Moreover, despite the presence of natural varieties of onyx coloration in nature, even in ancient times, masters learned to artificially give stone the desired shade.

Quote: "The possibility of artificial coloration could have been noticed on agate or opaque red carnelian, which is often found in dirty-brown tones, but after calcination in fire acquires a beautiful red color. Ancient people used this method 2000 years ago, and they already knew how to color stones in different colors by boiling them for several weeks in various solutions. For example, agates were usually boiled for several weeks in a pot with honey, then washed with clean water and boiled again for several hours in sulfuric acid; this resulted in a beautiful striped black coloration, which became known as onyx. Using similar techniques, they began to obtain green, red, blue, and yellow striped agates. Now this method has become so commonplace that there are almost no items made from uncolored natural stone; its coloration is always enhanced by various methods" - Alexander Fersman (1928) Entertaining Mineralogy
