2.19 Ct. Semi-Black Opal from Australia

This translucent 2.19 carat oval Semi Black Opal from Australia measures 11.40 x 8.42 x 3.94 mm, and it has been fashioned in a tablet cut to emphasize broad areas of play of color rather than high dome dispersion. The tablet cut here presents a low profile with a gently flattened dome, which optimizes color flash across the surface while maintaining uniform thickness for durable setting. Clarity is graded slightly included at eye level, noting fine internal matrix and minor pinpoints that do not disrupt the overall color performance, and the polish is excellent, delivering clean surface reflections that enhance contrast between body color and spectral flashes. No enhancement has been applied, and the natural state of the material allows accurate assessment of body tone and color intensity, which is recorded as intense, with saturated flashes of green, blue, and sporadic red against the semi dark ground typical of fine Semi Black Opals.

From a lapidary perspective this specimen displays a finely executed balance between cutting depth and orientation, the cutter having oriented the tablet to present the most consistent color patches when viewed face up, while retaining sufficient thickness to prevent fracturing during setting. The play of color is well distributed, with broad patchy patterning that shifts with small changes in angle, indicating a well preserved silica sphere arrangement. Color grade is intense, with high chroma in the primary flashes and a cooler hue in the surrounding potch, producing dynamic contrast and depth. For setting recommendations choose a low bezel or flush style that supports the thin profile without stressing the girdle, consider gentle prong work only if reinforced with a supportive underplate, and avoid excessive heat or ultrasonic cleaning to preserve the natural water content and internal structure. The Natural Gemstone Company presents this Semi Black Opal as a collector grade tablet cut piece, suitable for connoisseurs who value precise cutting strategy, natural condition, and vivid spectral performance.
