0.34 Ct. Yellowish Green Sapphire from Montana

This transparent 0.34 carat oval yellowish green sapphire measures 5.42 by 3.64 by 2.08 millimeters, and it has been precisely fashioned with a mixed brilliant cut to balance color and fire. The oval outline has been executed with careful symmetry to preserve face up coverage while allowing for the pavilion to relay light efficiently. The mixed brilliant cut combines a brilliant facet schema on the crown with modified pavilion faceting, a configuration that emphasizes scintillation from small facet junctions while retaining a broad flash of color through the table. The medium color intensity is evenly distributed across the table and shoulders, producing a subtle yellow green presence that remains lively without overpowering the stone. The excellent polish yields crisp facet junctions and uninterrupted light return, and the modest depth relative to the length and width produces a pleasing face up presentation for use in intimate jewelry proportions.

Clarity has been assessed as very very slightly included at eye level, a description that indicates that inclusions are minor and do not detract from the gem when viewed without magnification. For a buyer who evaluates gems at loupe and microscope, these inclusions typically appear as isolated pinpoints or faint crystals that are positioned to minimize impact on light performance. Because the mixed brilliant cutting pattern concentrates scintillation in the upper hemisphere, small internal features are often visually masked by dynamic flashes, preserving apparent purity across viewing angles. The stone has been heat treated, a widely accepted and stable enhancement in the trade that refines hue and tone by altering trace element states within the crystal lattice. This treatment does not compromise structural integrity, and it is disclosed fully, reflecting our commitment to transparency and technical honesty in describing each specimen.

Origin is Montana, a source known for producing sapphires with distinctive tertiary hues and fine crystalline habit, and this provenance carries implications for both the gemology and the ethical narrative of the piece. Montana sapphires can exhibit flora like yellow green and teal tones as a result of complex trace element chemistry, and in this stone the yellow and green contributions are balanced to a medium intensity that is versatile in design. From an ethical perspective, The Natural Sapphire Company maintains stringent sourcing protocols that emphasize traceability, responsible procurement, and respect for local communities. We work with suppliers who operate within legal frameworks and small scale mining contexts, and we document chain of custody where possible to provide purchasers with confidence in the source. For the conscious collector who evaluates not only optical merit but also provenance and impact, this Montana sapphire offers a clear narrative of origin, disclosed enhancement, and accountable supply.

In practical application this 5.42 by 3.64 millimeter oval is suited to refined settings where scale and detail matter, and the mixed brilliant cut allows it to read larger than its carat weight might suggest under a well considered mounting. For rings and pendants the oval axis may be oriented along the finger or neck to accentuate elegance, and a minimal prong setting will maximize light exposure while a low bezel can offer protection and a contemporary silhouette. A halo of small brilliant stones will amplify perceived size and color saturation, while a single stone solitaire will highlight the nuanced yellowish green hue and the very very slightly included clarity grade. Recommended care is standard for corundum, using warm soapy water and a soft brush for regular cleaning, avoiding sudden thermal shock or prolonged exposure to chemicals that could affect metal work. Each sapphire we present comes with detailed gemological notes and the stewardship statements provided by The Natural Sapphire Company, and we invite you to contact our team for magnified imagery, facet diagrams, or to arrange private viewing to assess how this Montana sapphire integrates into a thoughtful, ethically minded collection.
