60.63 Ct.Tw.Total Carat Weight Cabochon Opal Pair from Australia

This matched pair from The Natural Gemstone Company is a striking set of Boulder Opal doublets, presented as an opaque cushion shaped, multi color opal pair, weighing 28.07 carats and 32.56 carats respectively, and measuring 40.80 by 12.30 by 5.10 millimeters and 40.30 by 12.60 by 5.50 millimeters, each cut as a cabochon with intense color intensity and an excellent polish, originating from Australia. The term Boulder Opal describes opal that forms in ironstone matrix, often showing a layer of precious opal against a natural stone backing, and these pieces have been assembled as doublets, a recognized enhancement that layers a thin slice of precious opal over a dark backing to maximize play of color while maintaining structural strength. These stones are opaque in body tone yet display vigorous, multi spectral flashes across blue, green, and aqua fields, with linear banding that is visually distinctive and well preserved by the cabochon profile. The cushion outline has been executed to provide symmetry and surface area for the color to read consistently from multiple angles, and the excellent polish indicates careful lapidary work that enhances the apparent brightness of the color play while minimizing surface abrasions and handling marks.

From a grading perspective, several objective factors make this pair attractive to an informed buyer, starting with color and brightness, which in opal grading are primary determinants of value, and here the intense color intensity and strong play of color place these doublets at a higher tier among assembled opals. Pattern and distribution are also important, and the linear, layered pattern evident in these stones is desirable for certain design applications, offering a contemporary, striated aesthetic that reads well in matched pairs. Clarity in Boulder Opal is assessed differently than in transparent gemstones, and the opaque body with consistent matrix integration is acceptable, as the contrast between the opal slice and ironstone backing contributes to depth and legibility of color, rather than detracting from it. Cut and polish receive high marks, the cabochon cut being the traditional and most effective form for opal display, providing dome and curvature to reveal the spectral range as the light source shifts. The doublet enhancement should be disclosed to purchasers, and trained buyers will recognize that doublets preserve the most desirable appearances of rare opal material while offering improved durability and a more economical price point than matched solid opals of comparable color intensity.

For practical use and long term value, these Boulder Opal doublets offer advantages that educated collectors and designers appreciate, particularly for matched pair applications such as earrings, cufflinks, or matched inlay work, where weight parity and dimensional harmony matter, and this pair balances at 28.07 and 32.56 carats with near matching lengths and thicknesses. The assembly as doublets with a dark backing enhances color contrast and reduces the need for thick, fragile solid slices, increasing suitability for everyday wear when set securely, and the ironstone component typical of Boulder Opal provides a natural structural base that aligns with the doublet format. Care recommendations for doublets are straightforward, avoid exposure to high heat, prolonged immersion in water, or harsh chemicals, set with protective bezel or secure prongs to minimize edge impact, and consider professional cleaning and inspection periodically. For buyers seeking provenance, these opals originate from Australia, the globally recognized source for high quality Boulder Opal, and The Natural Gemstone Company stands behind accurate description of origin, enhancement, dimensions, and cut, providing transparent information that supports appraisal, design planning, and confident purchase decisions.
