Onyx from Mexico: A Gemstone of Beauty and Intrigue

Mexico holds a rich legacy in onyx mining, boasting an abundance of this captivating gemstone. With its distinctive layered bands and mesmerizing hues, onyx from Mexico has graced jewelry, sculptures, and decorative artifacts for centuries.

Origins and Formation

Onyx, a form of banded calcite, forms when mineral-rich waters slowly seep into underground cavities. As the water evaporates, the minerals crystallize layer by layer, creating the characteristic banding. Onyx from Mexico is primarily found in the central and northern parts of the country, with the main mining operations located in the states of Puebla, Chihuahua, and Oaxaca.

Types of Mexican Onyx

Mexico produces a variety of onyx types, each with its own unique appearance:

• Blue onyx: Featuring vibrant shades of blue, this variety is often used in jewelry and decorative items.
• Green onyx: Known for its emerald-like hue, green onyx is prized for its rarity and beauty.
• White onyx: This pure and translucent variety is highly sought after for its versatility.
• Black onyx: The classic black color of onyx is a result of impurities and is often used in jewelry and carvings.

Mining and Processing

The mining of onyx in Mexico is a labor-intensive process. Miners must carefully extract the mineral from the underground cavities using specialized machinery. Once extracted, the onyx is transported to processing facilities, where it is cut, polished, and shaped into various forms.
