0.71 Ct. Bluish Green Sapphire from Montana

This transparent 0.71 carat sapphire presents a bluish green hue of intense saturation, cut into a refined fancy shape measuring 8.02 by 3.60 by 2.79 mm. The piece is executed in a mixed brilliant cut, with a brilliant facet architecture on the crown and tapered step facets on the pavilion, a configuration selected to maximize face up brilliance while retaining optimal weight from the rough. The cutter prioritized optical symmetry, crisp facet junctions, and a controlled table size to enhance scintillation and contrast, with pavilion steps angled to direct light back through the crown for lively flash. Clarity is graded very slightly included at eye level, with small natural inclusions that do not interfere with light performance, allowing a clean window through the table and strong light return. The polish is excellent, achieved with meticulous final laps to produce mirror like facet surfaces that deepen the gem s transparency and color. Heat treatment was applied to stabilize and intensify the bluish green tone, yielding an intense color intensity that reads rich in daylight and warm artificial light, while the proportioned girdle and profile support both aesthetic spread and practical durability for fine jewelry settings.

This sapphire s journey from Montana to market reflects deliberate technical decisions at each stage, beginning with field selection of transparent crystal from an alluvial seam for its potential to yield a long fancy form. The cutting plan was oriented to the corundum crystal axis to minimize color zoning and to exploit pleochroism for an appealing face up appearance, bruting and preforming steps conserved weight, and progressive faceting under magnification secured precise angles and optical alignment. Final polishing and quality control included visual clarity evaluation at eye level and standardized color assessment, followed by documentation that verifies origin and treatment for The Natural Sapphire Company inventory. The result is a gem that marries geological character with exacting lapidary craft, a technically refined Montana sapphire prepared for a bespoke setting or for the connoisseur seeking a loose stone with palpable provenance, disciplined cutting, and a well considered balance of color, clarity, and brilliance.
