1.36 Ct. Bluish Green Sapphire from Montana

From the moment a rough stone first revealed a hint of teal among the gravels of Montana, this sapphire began a journey shaped by time, pressure, and the unique geology of its birthplace. Montana sapphires carry a story that is distinctly American, formed in cool, mineral rich veins that yield colors different from classic sapphires. This bluish green cushion shape sapphire, weighing 1.36 carat, captures that story. Its hue reads as a meeting of sky and forest, an intense color that is at once rare and familiar. When you hold it, you can imagine the slow work of rivers and ice that delivered the rough to the hands of miners who recognized its promise, then the careful selection and planning that would guide a cutter toward revealing its inner character.

In the cutting room, that promise was honored, the stone was cut in a faceted mixed brilliant style to balance fire and depth, and the cushion silhouette was chosen to celebrate both modern elegance and vintage warmth. The dimensions are 6.41 x 5.20 x 4.43 mm, a size that translates into a presence that reads as a true statement when set as a center stone. The mixed brilliant facets are designed to catch light and scatter it into a lively play of brilliance and scintillation, while the cushion outline softens the geometry for a look that flatters the hand and sits beautifully at the center of a pendant. The excellent polish ensures each facet meets the eye with clarity and finish, allowing light to travel cleanly through the stone and emphasize its intense color.

Clarity matters when you are choosing a gemstone meant to command attention, and this sapphire has a clarity grade of slightly included, evaluated at eye level. Those tiny natural inclusions are a signature of authenticity, they confirm a natural origin and add a fingerprint that makes this gem uniquely itself, while not detracting from its visual impact. At normal viewing distances and in wearable settings, the stone reads as transparent and lively, the inclusions remaining subtle companions to its color rather than distractions. The heat treated enhancement that this sapphire has undergone is a conventional, stable, and widely accepted practice within the trade, applied to heighten the stone's color and improve clarity in a manner that is stable over time. The result is an intense, consistent tone that will perform beautifully under everyday light, while the excellent polish keeps reflections crisp and attractive.

Size, color, and clarity come together in this sapphire to make it an ideal choice for a statement piece. At 1.36 carat and 6.41 x 5.20 mm, it has the physical presence to anchor designs such as a solitaire ring, a halo pendant, or a three stone ring where side stones can complement and elevate its bluish green heart. The mixed brilliant cut means it will flash with lively scintillation, catching attention from across the room, while the cushion shape gives it a wearable silhouette that balances boldness with refinement. Whether set in platinum for a contemporary cool contrast, in 18k yellow gold for warmth that enhances the green component, or in rose gold for a modern romantic take, this sapphire will remain the center of conversation.
