1.73 Ct. Multi Color Cabochon White Opal (Light Opal) from Australia

This 1.73 carat White Opal, Light Opal, presents as a translucent oval, precisely measured at 8.46 x 6.61 x 4.92 millimeters, cut in a classical cabochon style to emphasize internal play of color. The cabochon dome has been proportioned to maximize diffraction from the internal silica sphere lattice, yielding broad flashes and discrete patches of green, red and blue across the surface when viewed from multiple angles. Clarity is graded very slightly included at eye level, with inclusions confined beneath the polished dome and having minimal impact on light transmission. Color intensity is medium, providing an ideal balance between a gentle, luminous body tone and vivid play of color, while the excellent polish produces crisp, mirror like reflections on the surface that enhance perceived depth. This piece is untreated, with no enhancement, and its provenance is Australia, assuring natural formation and authentic optical structure.

From a craftsmanship and longevity perspective, the cabochon cut and meticulous polish used by The Natural Gemstone Company create a gem that will continue to captivate over the years. The dome profile protects the most vulnerable facets of the stone, reducing surface abrasion and preserving the clarity window through which the internal fire is seen. Because the play of color in opal arises from physical diffraction rather than applied coloration, the optical character is stable with normal wear, provided common care guidelines are followed. We recommend a low bezel setting to shield the girdle and edges, avoiding ultrasonic cleaning and extreme thermal shock to maintain hydration and structural integrity. Over time this White Opal, Light Opal will retain its shifting spectral display, and its balanced combination of medium body color, translucent depth, and precise cabochon execution will make it a lasting and technically refined center for fine jewelry, as offered by The Natural Gemstone Company.
