Opals are captivating gemstones known for their mesmerizing play of colors, often referred to as "opalescence." This captivating phenomenon is a result of the interplay of light within the opal's structure, creating a dazzling display of hues and patterns. However, the price of opal can vary significantly, influenced by a number of factors, including its quality, rarity, and origin.

This article will delve into the world of opals, exploring the key factors that determine their value and provide a comprehensive understanding of the price of opal for both collectors and potential buyers.
