4.03 Ct. Black Opal from Australia

One beautiful transparent 4.03 carat cushion shape multi color opal is presented, the gem measures 14.11 x 7.56 x 3.71 mm, it has a tablet cut that produces a broad face for the play of color to be viewed easily, color intensity is described as intense with vibrant flashes across the surface, polish is excellent and the tablet finish yields a clean reflective plane. This stone is identified as Black Opal, originating from Australia, and it is supplied as a doublet enhancement, meaning a thin slice of precious opal is assembled to a dark backing to intensify the perceived body tone and play of color while improving durability. The visual presentation shows pronounced blue and green flashes with secondary multicolor nuances, the color distribution appears even across the tablet surface with minimal visible potch zones, and the transparent nature of the material allows light to penetrate and interact with the opal layers producing strong orient and spectral display.

For the educated buyer the value proposition is clear, Black Opal material commands premium interest due to the darker apparent body tone and the resulting contrast that makes colors read as more saturated, this 4.03 carat size in a well proportioned cushion tablet is particularly desirable for collectors and designers seeking a statement piece that still fits comfortably into custom jewelry. The fact that this is a doublet is a material consideration in grading and pricing, doublets offer an economical route to larger surface area of premium color while requiring disclosure and slightly different conservation practices, they are more stable in daily wear than untreated thin opal slices but less robust than solid opal. Clarity discussion in opal context focuses on the absence of cracks and stability of the color play, this specimen shows no significant fissures or crazing under standard viewing and has an excellent polish which indicates professional lapidary work. Provenance from Australia adds geological credibility as the principal source of high quality black opal, and at The Natural Gemstone Company we document enhancement and origin in our descriptions to support transparent purchase decisions. For setting recommendations consider bezel or inlay designs that protect the edge of the tablet, avoid extreme heat and ultrasonic cleaning, and contact us for additional imagery and certifiable details if you require further technical information.
