1.30 Ct. Multi Color Semi-Black Opal from Australia

This listing presents a translucent Semi-Black Opal from Australia, offered by The Natural Gemstone Company, a 1.30 carat pear shape multi color specimen with exact dimensions of 9.03 x 9.32 x 2.93 mm. The overall body is translucent with a subdued darkening that positions the material within the semi black range, providing an optimal balance between depth and brightness. The tablet cut produces a low profile and broad surface area, allowing an expansive view of the opal play, and the pear outline has been executed to maintain symmetry while maximizing the face up color area. Color response is intense, exhibiting a saturated, multi color play that shifts with angle and light, and the dominant tones captured include vivid reds, electric blues, and lively greens which appear as broad flashes and patches across the table, creating dynamic movement and strong color contrast against the semi black background. The origin from Australian fields is consistent with the structural regularity of the silica spheres that produce the pronounced spectral diffraction, and the combination of origin, body tone, and color intensity makes this piece particularly attractive to connoisseurs seeking a high impact, natural opal.

From a clarity and finish perspective this opal is graded eye clean when evaluated at normal viewing distance, with no visible surface reaching inclusions or potch interruptions that detract from the visual flow of color. The excellent polish enhances the modal brilliance of the play of color, ensuring that light transmission and surface reflection are optimized, and the tablet cut has been carefully executed to preserve the laminar color patches while retaining a protective edge thickness. The tablet cut is characterized by a relatively flat or gently domed table, a minimal crown, and a contoured pavilion that in this material is designed to reveal internal color layers rather than faceted sparkle, making the cutting philosophy here oriented toward maximizing color saturation and pattern visibility. No enhancement has been applied, the piece is in its natural state, and this unmodified condition maintains the integrity of the opal matrix, avoids dye or resin treatments, and allows accurate assessment of body tone, translucency, and color intensity. As a Semi-Black Opal the presence of subtle background darkening increases perceived color saturation, and the interplay between translucent body and vivid play of color yields depth that shifts with movement and light incidence.

For setting and handling considerations this 1.30 carat, 9.03 x 9.32 x 2.93 mm pear tablet is ideally suited for pendants and earrings where the shallow profile benefits wearability, and it can also be mounted in rings with a protective bezel to safeguard the relatively thin 2.93 mm thickness from lateral impact. The recommended mounting approach uses a low bezel or cup that secures the stone at the girdle with a continuous rim, this protects the edge and reduces the risk of chipping while maintaining maximum face up exposure of the play of color. Opal hardness typically lies between 5.5 and 6.5 on the Mohs scale, therefore care should be taken to avoid hard knocks, abrasive cleaning, and extreme thermal shock, and routine care should employ a soft cloth, warm water, and mild soap, avoiding ultrasonic cleaners, steam cleaning, and prolonged exposure to harsh chemicals. The Natural Gemstone Company stands behind the provenance and description of this opal, the piece is untreated and Australian in origin, and detailed imagery and additional angle shots are available on request along with certification options for trade and insurance purposes.
