1.35 Ct. Bluish Green Sapphire from Montana

This one beautiful transparent 1.35 carat round bluish green sapphire is offered by The Natural Sapphire Company, it measures 6.44 x 6.36 x 4.51 mm and is expertly cut in a mixed brilliant style to maximize brilliance and strong face up color. The gem displays an intense color intensity, a rich bluish green that ranges from deeper teal in the pavilion facets to a slightly brighter green blue on the crown as light penetrates and reflects. At this weight and with these dimensions a collector will appreciate the stone as a versatile size for a solitary ring or as a striking center for a custom pendant, while still remaining elegantly proportional for delicate settings. The overall transparency allows clean light travel through the gem, and the face up appearance in natural light photographs shows a saturated but lively tone that reads as distinctly Montana in character.

From a gemological perspective the sapphire presents a clarity grade of very very slightly included, evaluated at eye level, which means that inclusions are minute and do not materially interfere with brightness or durability when viewed without magnification. The mixed brilliant cut combines step and brilliant facets in a way that enhances both scintillation and depth, creating a dynamic interplay of flash and color. The excellent polish amplifies this effect, producing crisp facet junctions and minimal surface disturbances, which preserves maximum light return and allows the intense bluish green to show with clarity. The proportions and pavilion depth work together to balance internal reflection and dispersion, giving the stone an appealing face up size relative to its carat weight. Measured dimensions indicate careful planning by the cutter to yield an efficient spread in a round silhouette, and the symmetric girdle and well executed facets contribute to stable setting options and consistent visual performance.

We are committed to full disclosure, and this sapphire has been heat treated, a standard and widely accepted enhancement used to refine color and clarity in corundum, it is permanent under normal wear and does not require special care beyond routine precautions for fine gemstones. The gem originates from Montana, a source known for producing sapphires with unique and often highly desirable teal and greenish blue tones that differ from standard blue sapphires of other regions, Montana material is prized for its natural character and is often associated with responsible small scale mining traditions. The Natural Sapphire Company maintains traceable supply chains and works with partner mines and local agents who adhere to ethical labor practices and environmental safeguards whenever possible.

Heat treatment is openly stated to allow informed purchasing, and the Montana origin offers a distinct narrative for collectors who value geological story and locality over anonymous mass produced material. This gem is well suited to settings that minimize risk of abrasion to the girdle and that enhance the stone color, such as bezel designs that offer protection while retaining the round outline, or classic four prong mounts in warm or neutral metals that can provide a complementary contrast. The Natural Sapphire Company can assist with custom design options, secure setting recommendations, and guidance on long term care, and we encourage clients to commission an independent grading report for long term documentation and insurance purposes.
