Determining the value of jasper involves considering several factors, including type, quality, size, and market demand. For instance, a small, tumbled piece of common jasper might be worth a few dollars, while a large, high-quality specimen of a rare variety, like imperial jasper or bruneau jasper, could be valued at hundreds or even thousands of dollars. The assessment relies on characteristics like color vibrancy, patterns, inclusions, and overall aesthetic appeal.
Understanding the valuation process is crucial for both buyers and sellers. Accurate pricing ensures fair transactions and fosters trust within the marketplace. Historically, jasper has been prized for its ornamental beauty and purported metaphysical properties, contributing to its enduring value across cultures. This long-standing appreciation has led to the development of specialized markets and grading systems that further refine the valuation process.
