Kyanite Specimen Value Guide

Kyanite is a striking aluminum silicate mineral prized by collectors for its distinct bladed crystal structure and vibrant blue hues, derived from the Greek word 'kyanos'. Its geological significance and use in high-temperature ceramics make it a fascinating specimen that bridges the gap between industrial utility and aesthetic beauty.

What Is Kyanite Specimen Worth?

The typical price range for Kyanite Specimen is $10 - $20 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Intensity and saturation of the blue color, with deep, consistent hues commanding higher interest.
• The size and integrity of the crystal blades, as well as the presence of a contrasting matrix like quartz.
• Geographic origin, with notable specimens coming from Brazil, Switzerland, India, or specific US localities.
• Overall transparency and the absence of significant fractures or structural damage to the delicate blades.

How to Identify Kyanite Specimen?

• Look for long, bladed crystal habits that are characteristic of metamorphic aluminum-rich rocks.
• Test for anisotropic hardness: the specimen will measure approximately 4.5 to 5.0 along the length of the crystal and 6.5 to 7.0 across the width.
• Observe the color zoning, which typically features a deep blue center fading to a lighter blue or white toward the edges.
• Check for a pearly to vitreous luster on the cleavage faces of the crystal blades.

History of Kyanite Specimen

Kyanite's name comes from the Greek word 'kyanos,' meaning blue, referencing its typical color. It has been used for various purposes throughout history, including as an abrasive, in high-temperature ceramics, and occasionally as a gemstone for collectors due to its unique optical properties and striking blue hues. It is known for its anisotropic hardness, meaning its hardness varies depending on the direction it is scratched.
