"6.68 carat 7.35 ratti natural IIGJ certified Austrailian Cushion shape opal stone"
The 6.68-carat natural Australian opal, certified by the Indian Institute of Gemology (IIGJ) and presented in an elegant cushion shape, represents a stunning example of this remarkable gemstone. This opal’s weight of 7.35 ratti, a traditional unit of measure used in gemology, underscores its substantial size and presence. The cushion cut, characterized by its rounded corners and larger facets, is designed to enhance the stone’s inherent beauty and maximize its visual appeal. This particular shape is highly esteemed for its ability to combine the classic charm of a square cut with the softer lines of a round shape, creating a balanced and sophisticated look that highlights the opal’s natural attributes.
Australian opals are renowned for their exceptional quality and stunning play-of-color, a phenomenon that is both enchanting and distinctive. This play-of-color is the result of the opal’s unique internal structure, where microscopic silica spheres are arranged in a regular pattern, allowing light to diffract and produce a spectrum of shifting hues. The opal in question, with its 6.68-carat weight, provides a substantial canvas for this optical effect, ensuring a rich and dynamic display of colors that can range from deep blues and greens to fiery reds and oranges. The larger size of the opal allows for a more pronounced and captivating play-of-color, making it a standout piece in any jewelry collection.

The geological conditions in these areas create an ideal environment for the formation of opals with vibrant and diverse color patterns. This 6.68-carat opal, hailing from such a prestigious source, embodies the high standards associated with Australian opals.
The cushion cut of this opal is particularly noteworthy. This cut, also known as a cushion brilliant or cushion antique, features rounded corners and larger facets compared to other cuts.

The value of such an opal is influenced by several factors, including its size, color, and clarity. The 6.68-carat weight of this opal places it in the higher range of opal sizes, which is a key factor in determining its value.
