The carat weight of a gemstone is a primary factor in determining its overall value, with each carat representing 200 milligrams. The opal in question, weighing an impressive 14.3 carats, highlights its considerable size, making it a rare and valuable specimen. This substantial weight not only enhances its visual impact but also contributes to its desirability among collectors, investors, and connoisseurs of fine gemstones.

The ratti measurement, used in South Asia to denote gemstone weight, translates to 15.73 ratti for this opal, adding a culturally significant perspective to its size and emphasizing its prominence within the context of traditional gemstone evaluations.

The opal’s shape, an elegant oval, is a classic cut that enhances its natural beauty and visual appeal. The oval cut is known for its symmetrical and elongated form, which accentuates the gemstone's play-of-color and maximizes its brilliance. This shape is particularly advantageous for opals, as it allows for a generous display of the gem’s intricate internal patterns and colors. The oval cut’s smooth, flowing lines contribute to the opal’s refined appearance, creating a harmonious balance between modern sophistication and timeless elegance. The craftsmanship involved in achieving this cut reflects the skill and artistry required to bring out the opal's full potential, showcasing its vibrant hues and dynamic play-of-color to their fullest extent.

One of the most captivating aspects of opals is their play-of-color, a phenomenon that results from the gemstone’s unique internal structure. This optical effect arises from the diffraction of light through the opal’s microscopic silica spheres, which are arranged in a regular, orderly pattern. The result is a shifting spectrum of colors that can include an array of vivid hues such as red, orange, yellow, green, blue, and purple. Each opal exhibits a distinctive play-of-color, making every gemstone unique. The 14.3 carat opal’s size and oval cut are particularly conducive to showcasing this mesmerizing effect, allowing the full spectrum of colors to be displayed in an expansive and visually arresting manner.

Australian opals are renowned globally for their exceptional quality and diverse color displays. The opal in question hails from Australia, a country with a prestigious reputation for producing some of the finest opals in the world. Australia’s major opal-producing regions, including Coober Pedy, Lightning Ridge, and Andamooka, are known for their high-quality stones, each with unique characteristics. The opal’s Australian origin adds significant value, reflecting the esteemed status of Australian opals in the global market. The rich and varied color palette of Australian opals, combined with their remarkable play-of-color, contributes to the gemstone’s allure and desirability.
