1.29 Ct. Semi-Black Opal from Australia

One beautiful opaque 1.29 carat freeform shape multi color opal, with dimensions 13.32 x 9.57 x 1.76 mm, is offered by The Natural Gemstone Company. This specimen is identified as a Semi Black Opal, originating from Australia, and presents an intense color intensity with an excellent polish. The cut is not applicable in the traditional faceted sense, given its freeform cabochon profile, and the clarity is graded as eye clean when evaluated at normal viewing distance. There has been no enhancement, it is a natural solid opal, and its surface and body tone combine to give a dramatic display of color shifts under changing light. The combination of a modest carat weight, substantial surface area, and strong play of color make this opal versatile for many jewelry applications while retaining a distinct character that appeals to informed collectors and designers.

In terms of gemological grading and value considerations, a Semi Black Opal occupies a desirable position in the opal hierarchy because its darker body tone enhances contrast and saturation of spectral color. Clarity grading for opals differs from that used for transparent gemstones, so the designation eye clean indicates that the stone shows no distracting inclusions, fissures, or potch at normal viewing distance, preserving visual integrity and durability. The intense color intensity cited for this piece refers to both the strength of the play of color and the saturation of individual hues, which are key drivers of market value. The excellent polish contributes to optimal light return and surface luster, which allows the patterning and color to be read clearly from multiple angles. Origin from Australia is significant, because Australian opals, and in particular black and semi black material from well known fields, are sought after for their stability and superior color play compared with many other sources.

When considering customization into finished jewelry, the freeform shape and measurements lend themselves to a wide range of settings and design directions. For protective everyday pieces such as rings, a secure bezel or partial bezel setting is recommended because the depth at 1.76 mm is moderate, and opal benefits from settings that shield thin edges from impact. For designs intended to maximize the display of color, an open back mounting or an elevated bezel with minimal metal coverage across the table will allow light to enter and enhance play of color. The thin profile makes this opal ideal for pendants and drop earrings where a low profile is desirable, and it can be incorporated into a halo setting with accent stones to emphasize its multi color character. For modern or masculine pieces, the freeform silhouette complements custom inlay work, flush bezels, or mixed metal treatments. Metal choices such as 14 karat yellow gold will warm certain orange and red flashes, while white gold or platinum will emphasize cooler blues and greens. For clients seeking contrast, a delicate pavé surround can add brilliance without overpowering the opal, and for a minimalist approach a single bezel in satin finish will create a contemporary, wearable piece.

The Natural Gemstone Company can assist with design consultations, including CAD mockups, metal selection, and setting recommendations that take into account both aesthetic goals and practical considerations for wear and care. Opal requires gentle handling and should be set to minimize exposure to hard knocks and sudden temperature changes, and specialists will advise on secure prongs or bezels and on appropriate adhesives only where necessary. We can also advise on matching stones should the client wish to create a pair of earrings, a matched set, or a companion stone for a multi stone composition. Documentation of the gem attributes, including weight, dimensions, clarity assessment as eye clean, polish grade, absence of enhancement, and Australian origin, will accompany each purchase to support provenance and appraisal. For bespoke commissions, lead times, secure shipping, and insurance options will be outlined, and our team at The Natural Gemstone Company is available to guide educated buyers through technical details so that the finished jewelry meets both design aspirations and long term value expectations.
