1.47 Ct. Bluish Green Sapphire from Montana

This sapphire begins its journey in the mineral rich gravels and quartz veins of Montana, a region long respected for producing sapphires with distinct, cool tones. Recovered through careful, local mining practices that prioritize minimal disturbance, the rough material is inspected on site for transparency and crystal quality. The piece that became this finished gemstone displayed a favorable combination of clarity and color in the rough, characteristics that indicated it would respond well to precision cutting and controlled enhancement. From the moment of discovery the stone was documented and tracked through each stage of handling, a continuity of custody that preserves provenance without interrupting the natural history written into the crystal structure. Early sorting focused on separating transparent, gem quality rough from matrix and opaque material, and further evaluation identified the stone as suitable for a faceted oval, a shape that both maximizes yield and complements the bluish green color inherent to many Montana sapphires.

The lapidary work respected the original crystal form while seeking to unlock optimal light performance. Skilled cutters fashioned the gem into an oval, with finished dimensions of 7.54 x 6.11 x 4.16 mm, applying a mixed brilliant cutting style to balance fire and overall brightness. The mixed brilliant approach combines crown facets with a pavilion cut designed to return light efficiently, a particularly effective solution for stones with this tone and saturation. The resulting weight is 1.47 carat, and the gemstone presents as transparent with an intense color intensity that reads bluish green under neutral lighting. Clarity was assessed at eye level as very slightly included, evaluated at eye level, meaning that minor internal features are present but do not detract from the gem at normal viewing distances. To stabilize and enhance the color, the stone underwent a standard heat treatment, a widely accepted practice in the trade that improves hue and saturation while maintaining the natural crystalline integrity of the corundum. The polish on the facets was executed to an excellent standard, delivering crisp facet junctions and a smooth table surface that contribute to the gem’s overall visual appeal.

After cutting and treatment the stone entered a thorough quality control and grading process, where measurements were confirmed, weight was recorded, and color and clarity assessments were documented for customer reference. Photography was undertaken under calibrated lighting to present an accurate depiction of the gem, and comparative viewing under multiple light sources was used to describe how the bluish green tone shifts subtly from cooler to slightly warmer notes. The Natural Sapphire Company maintains detailed records for each item offered, including origin, enhancement history, and the report of grading observations. This documentation supports both consumer confidence and transparent provenance, enabling the gem to move from our secure inventory into bespoke jewelry production or into a private collection with full background information.

In the final stages of the journey the gemstone is prepared for presentation, packaged with protective measures that preserve the cut and polish during transit, and made available with clear, factual specifications to assist in design and setting decisions. The finished oval offers a versatile silhouette for a range of mounting styles, and its moderate size and distinct bluish green character make it suitable for a solitary center stone or as an accent within a more complex composition. Throughout every phase from Montana extraction to finished gem, the process emphasized accurate measurement and honest description, so that the buyer receives a precise account of what makes this sapphire distinctive. The Natural Sapphire Company offers this 1.47 carat, 7.54 x 6.11 x 4.16 mm oval faceted, mixed brilliant cut sapphire with transparent clarity, very slightly included, evaluated at eye level, intense color intensity, excellent polish, and heat treated enhancement, accompanied by the provenance and grading details that reflect its careful journey from mine to market.
