1.81 Ct. Boulder Opal from Australia

This listing describes one beautiful opaque 1.81 carat cushion shape multi color opal, opal type is Boulder Opal, with dimensions of 9.66 x 6.11 x 3.10 mm. The stone is fashioned in a tablet cut, presenting a broad, flat face with a low profile that emphasizes the opal body and color distribution. The gem displays intense color intensity across a vivid blue and green play of color, with subtle variations that contribute to a lively and dynamic appearance under changing light. The piece is free of enhancements, with enhancement noted as no enhancement, and it is sourced from Australia, a well established origin for high quality boulder opal material. The polish is excellent, resulting in a glossy surface that enhances the stone color and overall presentation, and the natural ironstone backing visible along the girdle area confirms the boulder opal character and contributes to durability.

From a gemological and practical perspective, the tablet cut and modest thickness make this opal particularly well suited for flat setting styles, including bezel work, inlay, and low profile pendant applications where the stone surface can be protected. The cushion shape offers a classic, versatile outline that balances wearability and design flexibility. Care recommendations include avoiding exposure to harsh chemicals, extreme heat, and ultrasonic cleaning, and using only mild soapy water and a soft cloth for routine cleaning. Due to the opaque nature and the ironstone host, the stone is more robust than many thin crystal opals, yet consideration for protective mounting and avoiding sharp impacts is advised.
