Tourmaline is a fascinating gemstone known for its wide range of colors and unique properties. While it is not a type of jade, it shares some similarities in terms of its use in jewelry and its cultural significance. In this article, we will explore how much you should pay for tourmaline, its characteristics, and what factors influence its price.
What is Tourmaline?
Tourmaline is a complex borosilicate mineral that comes in a variety of colors, including pink, green, blue, yellow, and black. It is known for its pleochroism, which means it can show different colors when viewed from different angles. Tourmaline is also piezoelectric, meaning it can generate an electric charge when subjected to mechanical stress.
Characteristics of Tourmaline
- Color: Wide range, including pink, green, blue, yellow, and black.
- Hardness: 7 to 7.5 on the Mohs scale, making it relatively durable.
- Luster: Vitreous to resinous.
- Transparency: Transparent to opaque.
- Crystal Structure: Trigonal, often forming elongated prisms.
Factors Influencing the Price of Tourmaline
The price of tourmaline can vary widely depending on several factors. Here are some of the key factors that influence the cost of tourmaline:
Color
Color is the most important factor in determining the price of tourmaline. The most valuable tourmalines exhibit vivid, saturated colors. Some of the most sought-after colors include:
- Paraiba Tourmaline: Neon blue or green, found in Brazil and Africa.
- Rubellite Tourmaline: Deep pink to red, resembling ruby.
- Indicolite Tourmaline: Deep blue to blue-green.
- Chrome Tourmaline: Vivid green, colored by chromium.
Clarity
Clarity refers to the absence of inclusions or internal flaws. High-grade tourmaline should be eye-clean, meaning no inclusions are visible to the naked eye. However, some inclusions are acceptable if they do not detract from the stone’s overall beauty.
Cut
The cut of a tourmaline greatly affects its brilliance and overall appearance. A well-cut tourmaline will have symmetrical facets and a good polish, enhancing its natural beauty. The cut should also maximize the stone’s color and minimize any visible inclusions.
Carat Weight
Larger tourmalines are generally more valuable, especially if they exhibit high-quality color and clarity. However, smaller stones can also be of high grade if they meet the other criteria.
Origin
The origin of the tourmaline can also influence its price. Tourmalines from certain locations, such as Brazil, Africa, and the United States, are often more valuable due to their high quality and unique characteristics.
Treatment
Some tourmalines are treated to enhance their color or clarity. While treated stones can be beautiful, they are generally less valuable than untreated stones. It is important to ask about any treatments when purchasing tourmaline.
