1.76 Ct. Cabochon Fire Opal from Mexico

One beautiful transparent 1.76 carat oval shape multi color opal with dimensions of 8.56 x 6.41 x 6.15 mm, this gemstone is a Fire Opal from Mexico and is represented by The Natural Gemstone Company. The stone is a cabochon cut, exhibiting a smooth domed surface that maximizes the internal play of color, and it presents an intense color intensity combined with transparency that allows light to move through the body of the gem. The clarity grade is very slightly included, evaluated at eye level, and the polish is excellent. There is no enhancement, the piece is natural, and the combination of size, weight and optical properties makes this Fire Opal a rare and compelling choice for a discerning collector or a custom jeweler looking for a standout center stone.

From a gemological perspective, this fire opal offers characteristics that educated buyers seek when evaluating natural colored gemstones. The transparency and intense orange to reddish body color are primary value drivers for Mexican fire opal, and the multi color play evident within this cabochon increases visual complexity and desirability. The clarity grade of very slightly included, evaluated at eye level, means that internal features are minimal and do not disrupt the overall appearance when viewed in normal display or setting conditions. The cabochon cut and excellent polish accentuate the stone surface, producing rich internal reflections and a silky luster that reads as premium quality under both diffuse and direct lighting. The absence of enhancement confirms that the observed hue and clarity are wholly natural, a significant factor for buyers who prioritize untreated gemstones for investment grade and heirloom jewelry.

The dimensions of 8.56 x 6.41 x 6.15 mm and the oval shape make this Fire Opal especially well suited for custom jewelry applications, as the proportions fall into a frequently used size range for ring centers and pendants. At 1.76 carat, the stone carries enough presence to command attention, yet remains practical for daily wearable pieces without excessive bulk. The cabochon dome height of 6.15 mm provides volume and depth, which is ideal for bezel settings that protect the girdle and deliver a secure mount, while also offering designers the option of low profile bezels for comfortable rings or higher open settings to enhance translucency. Oval shapes adapt well to classic solitaire designs, halo settings that amplify color through contrasting gemstones, and asymmetric or artisan mounts that showcase the opal as a focal sculptural element. For designers considering metal choices, warm tones such as 18 karat yellow gold or rose gold harmonize with the fire opal body color, while white metals provide a contemporary contrast that highlights the internal play of color.

Caring for an opal is straightforward but important to preserve its beauty and value. Fire opal sits around five and a half to six and a half on the Mohs hardness scale, which means it requires sensible protection from hard knocks and abrasive contact. Ultrasonic and steam cleaning should be avoided, and routine cleaning with a soft cloth and mild soapy water is recommended, followed by gentle drying. When commissioning a custom setting through The Natural Gemstone Company, consider protective bezel mounts or low profile prongs and avoid overly exposed gallery designs for everyday wear. Because this opal is natural and untreated, its color is intrinsic and stable with appropriate care. If you would like, we can provide exact setting dimensions, profile recommendations, and matching accent stones to achieve a balanced custom piece.
