1.34 Ct. Bi Color Sapphire from Montana

This transparent 1.34 carat oval bi color sapphire is presented by The Natural Sapphire Company as a finely balanced combination of size, cut, and optical interest. The gem measures 6.64 by 5.24 by 4.42 millimeters, and it is fashioned in a classic oval outline with a mixed brilliant cut that marries a faceted crown with a faceted pavilion to maximize return of light and scintillation. Clarity has been evaluated at eye level as very very slightly included, a grade that indicates exceptional visual purity to the unaided eye while still retaining natural character that confirms its origin and natural formation. The stone displays excellent polish, which means the facet junctions are executed with precision, surfaces are smooth, and the overall finish enhances both brilliance and lustre. The combination of transparency, careful cutting, and superior polish allows this sapphire to present a lively presence on the finger, in a pendant, or as the centerpiece of bespoke jewellery.

The most compelling attribute of this sapphire is its bi color nature, presented with medium intense color intensity that gives the gem a distinct personality. Bi color sapphires exhibit two discernible hues within a single crystal, and that duality is an alluring feature for collectors and connoisseurs alike. In this example, the color shift reads as a harmonious blend that can range from warm peach to delicate pink and soft golden to light orange, depending on the viewing angle and light source. This effect is related to pleochroism and subtle color zoning, natural phenomena in corundum that cause different wavelengths of light to be absorbed variably along different crystallographic directions. The medium intense saturation keeps the hues vivid enough to be seen clearly, while preserving the stone's ability to pair elegantly with varied metals and designs. For an educated buyer, the presence of two balanced hues increases desirability because it offers versatility in styling and a unique visual signature that is difficult to replicate in synthetic or heavily treated material.

This sapphire originates from Montana, a region with a storied history for producing characterful and collector worthy sapphires. Montana sapphires are prized for their range of natural colors and their tendency to show complex, layered coloration, rather than a single flat tone. Geological conditions in Montana produce corundum crystals that often contain trace element combinations responsible for delicate and unusual colors, and these attributes contribute to the gemological interest and provenance value. The gem has been heat treated, an industry standard enhancement that is widely accepted when disclosed and appropriately performed. Heat treatment in sapphires is used to improve color uniformity and to reduce certain inclusions, and when done well it is permanent and stable under normal wear conditions. At The Natural Sapphire Company we ensure full disclosure of such treatments because transparency about enhancement is essential for long term value assessment. The clarity grade, the natural bi color phenomenon, and the heat treatment together provide a clear picture for valuation, conservation, and daily wear expectations, enabling collectors and buyers to make informed decisions.

This sapphire is exceptionally versatile, suitable for both casual and formal settings, which is a key consideration for buyers seeking a single stone that performs across contexts. In everyday wear the stone harmonizes with simple, modern settings where its dual hues add quiet complexity that complements jeans and tailored separates without appearing ostentatious. For formal occasions the medium intense color and the mixed brilliant faceting deliver sparkle and color depth that hold up under gallery lighting and evening illumination, making the gem equally at home in a classic solitaire ring, a halo design that amplifies its presence, or a three stone setting that plays off its bi color character. Metal choices can further emphasize different aspects of the stone, yellow gold warming the golden and peach tones, rose gold enhancing the pinkish notes, and platinum or white gold providing a modern contrast that highlights the stone's brilliance. For collectors The Natural Sapphire Company recommends considering the stone in custom work that showcases its unique color transitions, for example an open bezel or an east west mounting that allows light to pass through the oval face and reveal its layered palette. The overall balance of carat weight, clarity, and cut make this sapphire a practical and worthwhile choice for an informed buyer looking for a durable, beautiful gem with a distinct natural story.
