1.06 Ct. Bluish Green Sapphire from Montana

If you are searching for a single stone that will end your hunt for a meaningful engagement ring centerpiece, or if you are a collector seeking a distinct example of Montana beauty, this gem answers that call. This is a transparent 1.06 carat oval shape bluish green sapphire, with dimensions 6.57 x 5.62 x 3.68 mm, a mixed brilliant cut, and a clarity grade of eye clean evaluated at eye level, an enhancement of heat treated, and an origin from Montana. At The Natural Sapphire Company we understand how important both the technical statistics and the emotional resonance of a gem are, and this sapphire brings both in equal measure. If your priority is a stone that performs brilliantly in any light, while carrying a natural provenance and regal presence, this gem is designed to satisfy that exact need.

Consider the color and clarity first, because they are the primary language a sapphire speaks. This stone shows a bluish green hue with a medium intense color intensity that reads differently as the light moves. At certain angles the blue notes come forward with a cool marine clarity, and at others the green warmth surfaces, giving a living, dynamic personality that is rare at this size. The clarity is eye clean at typical viewing distance, which means you receive a clean window into the jewel without visible inclusions that would interrupt the play of color. The transparent body and excellent polish allow the color to breathe and evolve, whether set alone in a solitaire or paired with accent stones to amplify presence.

The geometric faceting of this oval mixed brilliant cut is central to why this sapphire returns so much life to the eye. The mixed brilliant approach combines the precise light return of a brilliant crown with the deeper spread and window control of a step influenced pavilion, creating an engineered map of facets that catch, break, and reflect light across a broad spectrum. The pavilion facets work with the crown facets to funnel light back to the viewer with energetic scintillation, while the table and girdle proportions in these dimensions provide a balanced window into the heart of the stone. This interplay of angles and facets produces a lively pattern of brilliance and flash, ensuring that every movement creates a new choreography of sparkle and color, and the excellent polish ensures those movements are crisp and clean rather than soft or hazy.

When you picture this sapphire in jewelry, imagine it set to maximize its oval outline and its mixed brilliant performance. For an engagement ring the elongated oval silhouette flatters the finger and presents a larger visual surface than a round of similar carat weight, while the 6.57 x 5.62 x 3.68 mm proportions are comfortable for everyday wear without sacrificing presence. White metals will emphasize the bluer tones, while warm metals will draw out the greener notes, giving you design flexibility based on the wearer style. For collectors, this stone represents a classic Montana example, with a dialogue between color and light that is both approachable and refined. The disclosed heat treatment is a stable, well accepted enhancement in the trade that enhances tone and clarity without compromising the natural origin story, and we disclose that fully so you can make a confident decision.

We describe the cutting details, the mixed brilliant geometry, the eye clean clarity, the medium intense color, the exact dimensions, and the enhancement openly, because transparency is part of how trust is built.
