This listing describes a high quality natural Black Opal, sourced from Australia, presented by The Natural Gemstone Company. The specimen is a translucent, multi color opal weighing 1.36 carats with dimensions of 13.93 by 5.27 by 2.48 millimeters, and rendered in a cushion overall outline with a tablet cut profile. The tablet cut has been executed to maintain a low domed face and flattened pavilion area, a geometry that optimizes face up color while retaining a robust thickness for setting. The body tone is characteristic of Black Opal, delivering a dark background that enhances spectral contrasts, and the translucency allows internal play of color to read with depth rather than surface sheen. Color intensity is graded as intense, and the face up presentation exhibits vibrant flashes that are particularly active when viewed at grazing angles, a direct result of careful orientation of the color bar during cutting.
Clarity has been evaluated at eye level, and the grade is eye clean, evaluated at eye level, reflecting an absence of visible inclusions or surface reaching fractures that would be observable under normal unaided inspection. The cutter preserved a clean window of play of color by trimming matrix and potch in selected areas, resulting in consistent color distribution across the tablet surface. The opal demonstrates a rich palette including dominant green spectral flashes complemented by intermittent red and orange pinfire, the latter providing strong contrast against the dark body tone and contributing to overall color intensity. The polish is excellent, achieved by progressive lap sequences and final fine polishing that yields a smooth, reflective surface, free of lapping lines and micro abrasions, which enhances both brilliance and the perception of depth in the color pattern.
From a craftsmanship and setting perspective the piece benefits from its tablet cut and modest thickness, which make it ideal for low profile jewelry designs where protection from impact is a priority. The 2.48 millimeter thickness is sufficient for bezel settings and inlay work, while an open back or partial bezel will allow light interaction for maximum play of color. For ring applications a fully framed bezel or channel setting is recommended to protect the elongated cushion tablet from edge stress, and for pendant or earring applications a recessed gallery will secure the stone without diminishing face up color. No treatments or enhancements have been applied to this opal, no enhancements, preserving natural hydration and internal structure, and the Australian origin is documented, supporting provenance and long term stability expectations under normal wear conditions.
As a technical summary for buyers who assess material on cutting and optical parameters, this Black Opal combines an elongated cushion outline with a tablet cut profile, 1.36 carats and 13.93 by 5.27 by 2.48 millimeter dimensions, a translucency that allows pronounced play of color, intense color intensity, eye clean clarity at eye level, and excellent polish, with no enhancements and Australian origin. The cutting strategy prioritizes color orientation and surface quality, resulting in a gem that performs strongly in both laboratory assessment and practical jewelry settings. The Natural Gemstone Company stands behind the descriptive grading and photographic representation, and we are prepared to advise on ideal mounting options to preserve the stone and maximize its optical performance.
