0.35 Ct. Bi Color Sapphire from Montana

Weighing 0.35 carat, this transparent round bi color sapphire presents a refined balance of presence and precision, qualities that define premium gemstones. The stone measures 4.22 by 4.22 by 2.81 millimeters, dimensions that are consistent with its stated carat weight and that allow for predictable placement in a range of fine jewelry settings. The mixed brilliant cut has been executed to maximize return of light while preserving the bi color character, and the overall presentation reflects thoughtful proportioning and lapidary skill. Origin information is clear and traceable to Montana, a source known for producing sapphires with distinctive color characteristics, and The Natural Sapphire Company is pleased to offer this example of transparent, finely worked material.

Cut and polish are decisive factors in how a gem displays its optical qualities, and this sapphire shows an excellent polish across the pavilion and crown facets. The mixed brilliant cut combines faceting styles to enhance scintillation and to maintain the integrity of the bi color effect, and the result is a lively, stable appearance under varied lighting conditions. Clarity is graded as very very slightly included, evaluated at eye level, which indicates inclusions are minimal and do not detract from the visual impact when the stone is set. Medium color intensity provides a balanced saturation that supports both the bi color nature and the overall transparency, producing a gem that reads as vibrant without appearing overly dark.

The 0.35 carat weight is an important attribute in assessing premium quality, because carat serves as a fundamental measure of scale and rarity, and when combined with superior cut, clarity, and polish, it indicates a stone of commercial and aesthetic value. At this weight, the sapphire offers a concentrated expression of color and fire, while remaining versatile for precise design work. For connoisseurs and designers, a sapphire of this size that is both transparent and bi color is significant, since transparent bi color material at similar proportions can be uncommon depending on the source. Heat treatment has been applied, a standard and stable enhancement that improves color and clarity in many natural sapphires, and it is disclosed here to provide a complete and accurate assessment of the gemstone.

Practical considerations for use and setting follow directly from these characteristics, with the 4.22 by 4.22 by 2.81 millimeter proportions supporting secure settings that showcase the stone without overpowering a design. The mixed brilliant cut and excellent polish ensure consistent light performance in bezel or prong settings, and the very very slightly included clarity grade means minimal masking is necessary to maintain brilliance. Taken together, weight, dimensions, cut, clarity, color intensity, polish, enhancement, and origin describe a specimen that exemplifies premium quality within its size class. The Natural Sapphire Company verifies these attributes to provide a clear, professional presentation for gemologists, jewelers, and clients seeking a well documented, high quality Montana bi color sapphire.
