1.37 Ct. Greenish Blue Sapphire from Montana

Across centuries and continents, sapphires have been revered as emblems of unwavering strength, spiritual insight, and refined taste, and the story of this Montana sapphire continues that long and noble tradition. From the early discoveries in American streams to the modern ateliers that shape each stone, Montana sapphires have earned a special place among connoisseurs and collectors who value provenance and provenance is more than geography, it is history, lineage, and the quiet confidence of a gem that has been formed by time. At The Natural Sapphire Company we honor that legacy by presenting gemstones that speak to both heritage and beauty, and this particular greenish blue oval sapphire embodies the union of geological story and human artistry. It is an heirloom in waiting, a gem whose presence will feel at once classic and resolutely personal, destined to anchor a collection or to become the focal point of a cherished piece.

This sapphire weighs 1.37 carats, it is oval in shape, and it measures 6.63 by 6.66 by 4.35 millimeters, each dimension reflecting careful planning and precise cutting. The gem displays a medium intense color, a nuanced greenish blue that shifts with light and angle, offering depths of tone that reward close viewing and casual admiration alike. Clarity is graded as very slightly included as evaluated at eye level, a characteristic that affirms its natural identity while preserving a luminous transparency that allows facets to sparkle freely. The cutting style is a mixed brilliant cut, a choice that combines the scintillating fire of a brilliant facet arrangement with the graceful proportions of an oval outline, and the polish is reported as excellent, contributing to a surface that reflects light with crispness and control. Enhancement has been applied through heat treatment, a widely accepted and stabilizing process that enriches color and clarity while maintaining the gem's integrity. The origin of this sapphire is Montana, a source celebrated for producing stones with distinctive character, a cool palette, and a sense of American provenance that resonates for buyers who value traceable sources.

What elevates this sapphire beyond its measurements is the exceptional cut and the resulting brilliance, qualities that make it a centerpiece in any collection. The mixed brilliant cut is executed to maximize return of light, balancing broad scintillation with lively pinpoint flashes that dance across the table and crown. From face up perspectives the oval outline presents balanced symmetry, while the proportioned pavilion and crown facets work in concert to create a depth of field that draws the eye inward, revealing the stone's internal color distribution and subtle pleochroic shifts. The excellent polish ensures that each facet edge and plane is a mirror for light, enhancing the stone's brightness and contrast, and producing the kind of optical performance that transforms a gem from pretty to unforgettable. Set in a simple solitaire, this sapphire will command attention with its focused brilliance, and when paired with complementary diamonds or warm metals, it will harmonize with surrounding elements while still asserting itself as the star of the composition.

Beyond its optical virtues, this Montana sapphire carries an intrinsic narrative of endurance and refinement, qualities that collectors and those seeking meaningful jewelry will appreciate. Its moderate size of 1.37 carats makes it versatile for engagement rings, pendants, or custom commissions where a singular gem should both anchor design and allow for wearable elegance. The greenish blue hue has a timeless appeal, recalling the cool depths of alpine lakes and the soft blue of twilight skies, a color story that ages with grace and transcends fleeting trends. At The Natural Sapphire Company we are committed to full disclosure and informed selection, and we present this gem with clarity about its heat treatment and its eye level clarity grade, so that your choice is grounded in both beauty and knowledge. For those who seek a gem that is steeped in history, yet crafted for contemporary life, this Montana oval sapphire offers a rare combination of provenance, precision cutting, and expressive color, a true centerpiece that will tell its story across generations, and invite new chapters of wear, admiration, and affection.
