The value of this gemstone is determined by a complex interplay of factors, including color, translucency, texture, carving intricacy, and historical significance. A small, low-quality piece might be available for a modest price, while a large, vibrant, and finely carved antique example can fetch a substantial sum, sometimes reaching millions of dollars. For example, a simple cabochon might be priced differently from an intricately carved pendant.
Understanding valuation is essential for both buyers and sellers. Throughout history, this precious material has been prized across cultures, often symbolizing purity, wisdom, and power. This enduring appeal, coupled with its relative rarity and the skilled craftsmanship involved in its transformation into jewelry and art objects, contributes significantly to its market value. Accurate appraisal requires expert knowledge, emphasizing the importance of consulting reputable gemologists and appraisers.
