0.82 Ct. Bi Color Sapphire from Montana

This oval 0.82 carat bi color sapphire is transparent and carefully finished, measuring 5.54 by 4.82 by 4.01 millimeters. The gem is cut in a mixed brilliant style, a choice that balances table facet brightness with pavilion faceting to enhance light return and visual depth. Clarity is graded as very very slightly included when evaluated at eye level, a designation that indicates minimal internal features that do not materially affect the gem image or its performance in typical jewelry settings. Color presents as medium intense in saturation, with a pleasing bi color distribution that offers a dual tone appearance across different viewing angles. The surface shows an excellent polish that contributes to overall brilliance and faceting symmetry. The sapphire has been heat treated, a stable and widely accepted enhancement in the trade, and its origin is Montana, a source noted for producing distinctive and collectible sapphires. The Natural Sapphire Company lists this stone with full disclosure of these attributes, reflecting provenance and treatment that are important to both connoisseurs and investors.

From a gemological standpoint the combination of cut, clarity, and color in this piece positions it as a refined example of a parti or bi color sapphire from Montana. The mixed brilliant cut maximizes scintillation and face up brightness while preserving weight from the rough, a valuable attribute in a stone that is under one carat. Very very slightly included clarity at eye level means that inclusions are subtle and do not detract from the stone when set, which supports both aesthetic appeal and market acceptability. Medium intense color saturation is often preferred for wearable colored gemstones, because it provides enough chroma to be clearly identifiable as sapphire without appearing overly dark in typical jewelry mounts. The bi color character adds rarity in a market where single hue sapphires predominate, and the way the colors interact with the facet pattern contributes to the stone being visually distinct and desirable for designers who seek pieces with personality and movement.

The investment potential of this 0.82 carat Montana bi color sapphire derives from several practical factors. First, origin matters in the colored stone market, and Montana sapphires have a recognized niche that appeals to collectors and buyers seeking provenance tied to a specific geological source. Second, bi color and parti sapphires are less common than uniform color examples, and rarity across color distribution can support a premium over comparable single color stones when quality is equivalent. Third, the quality indicators present here, including mixed brilliant cutting, very very slightly included clarity, and excellent polish, enhance marketability and long term desirability. Heat treatment is disclosed, and that treatment is standard practice that increases availability relative to fully untreated material, yet treated stones of attractive color and superior cut continue to show stable demand. The size at 0.82 carat places the stone below the 1 carat milestone, and while per carat pricing often scales with size, high quality small stones with distinctive color can command strong per carat values relative to more common material. For an investor, this means the stone combines scarcity of color type, verified origin, and high finish quality, which together contribute to a credible case for potential appreciation over a medium to long term holding period.

Practical considerations that support sound investment practice are straightforward and relevant to this sapphire. Documentation that records the specifiers detailed by The Natural Sapphire Company, including carat weight, dimensions, cut style, clarity grade, color intensity, treatment, and origin, is essential for secondary market liquidity and valuation. Independent grading reports from reputable laboratories enhance provenance and can materially affect resale outcomes, so securing such paperwork is recommended. Insurance, proper storage, and periodic professional appraisal help preserve both the physical condition and the monetary value of the gem. Buyers should also weigh investment timelines and market cycles, recognizing that colored gemstone markets can be less liquid and more specialist than the broader precious metal or blue chip asset markets, and that no gem investment carries an absolute guarantee of appreciation. That said, well documented, clearly described, and attractively cut examples of rare color distribution from recognized origins, such as this Montana bi color sapphire offered by The Natural Sapphire Company, present a reasoned opportunity for collectors and investors seeking diversification into tangible, aesthetically valuable assets.
