1.17 Ct. Multi Color White Opal (Light Opal) from Ethiopia

This 1.17 carat White Opal, also described as Light Opal, is a finely faceted oval with exact dimensions of 9.14 by 7.13 by 4.25 millimeters, cut in a mixed brilliant style to balance scintillation with the opal’s intrinsic play-of-color. Originating from Ethiopia, this specimen is unenhanced, and presents a medium color intensity with attractive multi-color flashes visible across the table and crown. The clarity is graded very slightly included when observed at eye level, indicating that any internal features are minimal and do not detract from visual appeal or light performance. The polish is evaluated as excellent, a critical factor for faceted opals where surface finish directly affects luster and the definition of color patches. From a gemological standpoint, opal’s amorphous silica structure produces diffraction-based play-of-color, and this piece’s balanced sphere arrangement yields a pleasing spectrum without the need for treatments, making it particularly desirable for collectors and buyers who prioritize natural, untreated gems.

For an educated buyer assessing value, several objective attributes make this White Opal a compelling option. The carat weight of 1.17 carats in an oval faceted shape presents a pleasing size for a center stone while maintaining comfortable wearability for rings. The mixed brilliant cut is intentionally chosen to maximize return of refracted light and to emphasize the opal’s multihued flashes, while the excellent polish delivers a crisp, reflective surface that enhances color saturation and contrast. The clarity grade of very slightly included, evaluated at eye level, means the stone is effectively eye-clean and the few inclusions present are unlikely to be visible once set, preserving both aesthetics and light performance. Notably, the gem is confirmed to have no enhancement, which increases its long-term market value and makes it preferable for purchasers seeking natural, untreated material. Ethiopian opals, first introduced to the international market in the late 2000s, are well regarded for vivid play-of-color and a broad palette of hues. Buyers should note general opal characteristics such as a refractive index in the neighborhood of 1.44 to 1.46 and a specific gravity near 2.1 to 2.2, parameters that influence how the gem sits and performs in jewelry designs.

When considering this opal as an engagement stone, its combination of natural color play, eye-clean clarity, and careful faceting make it an exceptional and meaningful alternative to traditional diamond centers. The oval proportions of 9.14 by 7.13 millimeters correspond to a classic center-stone footprint that pairs well with both solitaire and halo settings, and the mixed brilliant facets will provide lively sparkle under varied lighting conditions. Given the intrinsic material properties of opal, including relative softness compared with corundum and diamond and occasional hydrophane behavior reported among some Ethiopian opals, we recommend protective mounting choices to ensure long-term durability. A low bezel or halo setting will shelter the girdle and edges, while secure prong work that minimizes exposure to hard knocks will reduce risk of chipping. Maintenance guidance includes avoiding ultrasonic cleaners and harsh chemical exposure, limiting prolonged immersion in liquids if hydrophane behavior is a concern, and scheduling routine inspections to verify secure settings. At The Natural Gemstone Company we provide transparent disclosure of origin, cutting characteristics, and enhancement status, and we can supply additional documentation or photographs on request to assist in appraisal and insurance. For clients seeking a center stone that combines optical beauty, gemological integrity, and a story of natural origin, this Ethiopian White Opal presents a distinctive and informed choice for an engagement ring that celebrates individuality and lasting value.
