0.27 Ct. Bluish Green Sapphire from Montana

If you are searching for an engagement stone that feels both distinctive and timeless, or a rare collector piece that promises quiet sophistication, this Montana bluish green sapphire answers that need with clarity and confidence. This transparent 0.27 carat emerald cut sapphire measures 5.01 by 3.06 by 1.91 mm, and presents a medium intense color intensity with a clarity grade of very very slightly included when evaluated at eye level. The emerald cut allows the stone to display broad, mirror like facets that emphasize color and purity, while the excellent polish on each facet ensures that every plane reflects light with crisp definition. The result is a look that is both elegant and modern, ideal for a refined solitaire engagement ring or a bespoke collector setting.

The unmatched sparkle of this gem begins with corundum itself, the crystalline structure that makes sapphire so resilient and luminous. Corundum has a high refractive index, which means light bends and returns through the stone with a brightness that rivals other gem species, and this sapphire also shows subtle pleochroic behavior that lets its bluish green tones shift gently as the stone moves. Because this gem is very clean to the eye, light flows through its emerald cut galleries without obstruction, creating long, linear flashes and a deep internal glow rather than scattered sparkle alone. Heat treatment has been applied to enhance the color and clarity, making the medium intense hue more uniform while preserving the natural characteristics that give Montana sapphires their signature personality. Paired with the precision of an emerald cut and the superb polish, the optical interplay of refractive power, clean clarity, and directional pleochroism produces a sparkle that feels refined and singular.
