0.60 Ct. Cabochon White Opal from Australia

One translucent White Opal is presented from The Natural Gemstone Company, weighing 0.60 carat, and fashioned in an oval shape. The stone measures 8.20 x 6.04 x 1.89 millimeters, and it has been cut as a classic cabochon to maximize optical performance. The cabochon form yields a smooth domed surface and a broad viewing plane, attributes that are particularly effective for this type of opal, allowing the play of color to be observed across the entire face. Origin is Australia, a well established source for opal material that produces a wide range of body tones and color phenomena. The body of this specimen classifies as White Opal, exhibiting a pale translucent to near opaque ground that interacts with internal color flashes to produce its characteristic appearance.

Optically the gem shows a multi color play of color with a medium intense color intensity, which manifests as discrete flashes and patches of green, red, orange, and subtle blue tones across the surface. The distribution of color is even enough to create attractive movement when the stone is viewed from different angles, and the pattern tends toward small to medium scale patches that blend into a pleasing mosaic. Clarity has been assessed as very slightly included, evaluated at eye level, meaning that minor inclusions are present but do not significantly detract from the visual effect at normal viewing distances. The polish on the cabochon is excellent, producing a smooth reflective surface that enhances the perception of depth and the crispness of color play. No enhancement has been applied to this opal, the material being presented in its natural state.

From a gemological and handling perspective the physical parameters are well suited to a variety of jewelry applications that respect the material s hardness and sensitivity. The dimensions of 8.20 by 6.04 millimeters with a thickness of 1.89 millimeters indicate a moderate dome that balances optical performance with wearability. Opal typically has a Mohs hardness in the mid range, and it can be more susceptible to impact, thermal shock, and chemical exposure than many other gem materials, therefore protective mounting designs are recommended. Bezel settings or designs that provide a secure surround for the lower girdle area will help protect the stone during daily wear. Clean with a soft cloth and mild soapy water, avoid ultrasonic or steam cleaners, and limit exposure to harsh chemicals and abrupt temperature changes to preserve the integrity and appearance of the stone.

The Natural Gemstone Company provides this Australian White Opal as a natural, unenhanced example of quality cabochon cutting and optical character. The balance of medium intense color, translucent body, accurate cabochon proportions, and excellent polish make this gem appropriate for use in a refined pendant, a protective bezel set ring, or as a focal element in bespoke jewelry designs where the play of color is desired without aggressively bright body tone. Technical details are stated clearly to support informed choices by designers and collectors, and additional documentation or high resolution imagery can be provided upon request to aid in setting design and matching. This description aims to present the material attributes and handling considerations in a straightforward manner, enabling clear assessment for acquisition or incorporation into finished work.
