II. Geological Origins: Where Does Turquoise Come From?
Understanding the geological processes that give rise to turquoise provides insights into its formation and unique characteristics.
A. Formation in Arid Regions: Turquoise is typically formed in arid regions with specific geological conditions. It occurs in areas where copper-rich groundwater interacts with aluminum-containing rocks. The presence of phosphorus further contributes to the formation of turquoise.
B. Hydrothermal Processes: Hydrothermal processes play a crucial role in the formation of turquoise. Copper minerals in the earth’s crust dissolve in water and, under specific conditions, precipitate out as turquoise when they come into contact with aluminum-containing minerals.
C. Association with Copper Deposits: Turquoise is often found in association with copper deposits. It can form as nodules, veins, or crusts within rocks, and the quality and color of turquoise can vary depending on the specific geological conditions of its formation.
III. Identifying Turquoise: Gemological Characteristics
From a gemological perspective, turquoise possesses distinct characteristics that make it recognizable and distinguishable.
A. Color Variations: Turquoise is renowned for its blue to green color spectrum. The intensity and shade of turquoise can vary, with some stones displaying a more vibrant blue, while others exhibit a greener hue. The presence of copper contributes to the blue color, while iron content may influence the green tones.
B. Matrix and Inclusions: Many turquoise specimens exhibit a matrix, which refers to the host rock in which the turquoise is found. This matrix can add character to the stone and is often valued for its unique patterns. Inclusions, such as pyrite or quartz, may also be present and can contribute to the stone’s individuality.
C. Mohs Hardness: Turquoise has a moderate hardness of 5 to 6 on the Mohs scale. While it is suitable for various jewelry applications, care should be taken to avoid exposing turquoise to activities that may cause scratches or damage.
D. Porosity and Treatment: Turquoise is known for its porosity, meaning it can absorb liquids and oils. This characteristic can result in changes to the stone’s color over time. Some turquoise undergoes stabilization processes to enhance its hardness and improve color uniformity.
