0.97 Ct. Blue Cabochon Sapphire from Montana

This listing presents one beautiful transparent 0.97 carat round blue sapphire, measuring 5.50 x 5.50 x 3.05 mm, cut as a cabochon and finished to an excellent polish, provided by The Natural Sapphire Company. The stone displays a medium light color intensity that reads as a gentle, clear blue, with a transparency that allows internal character to be appreciated through the domed surface. Clarity is graded as included when evaluated at eye level, which means natural inclusions are visible without magnification, and the sapphire has been heat treated, a standard enhancement used to improve color and clarity while remaining stable and permanent under normal wear. The origin is Montana, a provenance that is respected among knowledgeable collectors and connoisseurs for its distinctive tones and geological history, and this combination of weight, dimensions, cut, clarity, treatment, and origin defines the sapphire as a distinctive and collectible example of American sapphire material.

From a gemological perspective the cabochon shape is an intentional choice, and it communicates specific visual and practical qualities to an educated buyer. A cabochon is a smooth domed cut rather than faceted, and for this transparent Montana sapphire the dome emphasizes internal depth and sheen, creating soft flashes and a pleasing, tactile presence in jewelry. The proportions suggest a shallow pavilion relative to a faceted stone, which influences how light travels and reflects inside the gem, favoring even color distribution and a luminous glow over scintillation. The excellent polish maximizes surface reflectivity and creates a mirror like finish on the dome, which enhances perceived transparency and color clarity. Clarity graded as included at eye level indicates that internal features such as tiny crystals, needles, or subtle veils may be present and will contribute to the gem s story, while not substantially compromising stability or structural integrity when the stone is properly set and cared for.

Color is a primary determinant of value in blue sapphires, and this gem s medium light color intensity positions it as an attractive option for buyers seeking a more delicate and classic blue, rather than a deeply saturated commercial stone. Montana sapphires are frequently appreciated for their range from cornflower and icy blues to greenish blue tones, and their color character often reflects the unique mineral environment of the region. The medium light intensity provides versatility for a variety of design aesthetics, pairing beautifully with both white and yellow metals, and it offers a subtle elegance that appeals to purists who prize natural color over heavy saturation. Heat treatment in this case serves to gently enhance the stone s hue and to reduce the prominence of certain inclusions, and because heat treatment is widely accepted and stable, it does not detract from the geological authenticity or long term wearability of the sapphire. For collectors who prioritize origin, the Montana provenance adds provenance value, as material from this region is less common on the global market than stones from larger producing areas, and collectors often value the narrative of locality alongside the physical attributes of the stone.

When considering use and practical value, the near one carat weight and 5.50 mm round face make this cabochon particularly suitable for a variety of settings, including bezel set rings, pendant centerpieces, and classic stud styles, where the dome can be protected and admired. Bezel settings are especially appropriate for cabochons, as they secure the stone s perimeter and protect the girdle, while allowing the dome to sit slightly above the metal plane for maximum visibility. Given the included clarity, careful setting will also help prevent undue impact on any internal features, and the excellent polish ensures that the surface will maintain a fresh look with routine care. Responsible care guidance includes avoiding prolonged exposure to harsh chemicals or extreme heat beyond normal wear, and seeking professional cleaning if there are concerns, because while heat treatment is stable, the presence of natural inclusions can make ultrasonic cleaning a matter for a jeweler s discretion. At The Natural Sapphire Company we disclose treatments and origin to maintain transparency and trust, and we are happy to provide supporting documentation or to discuss setting options, certification, and provenance. For the educated buyer seeking a transparent Montana blue sapphire with genuine character, sound craftsmanship in its cabochon cut, and a documented treatment history, this 0.97 carat example offers an appealing balance of natural identity and wearable refinement, backed by the expertise and ethical sourcing standards of The Natural Sapphire Company.
