0.58 Ct. Greenish Yellow Sapphire from Montana

This is a precision described, transparent greenish yellow sapphire of 0.58 carat, cut to an oval outline with millimeter dimensions of 5.52 by 4.56 by 3.21. The gem carries a mixed brilliant cut that combines a modified brilliant crown with a faceted pavilion designed to maximize return of white light with controlled scintillation. Measured depth as a percentage of average diameter is approximately 63.7 percent, a proportion that supports a lively balance between brightness and contrast without sacrificing face up spread. The cutting exhibits crisp facet junctions and excellent symmetry, which together with an excellent polish contribute to crisp facet definition and strong, well controlled reflections when mounted.

Technically the mixed brilliant faceting pattern was executed to exploit the sapphire crystal orientation for optimal optical performance. The crown angles have been cut to favor a generous table and broad star and bezel facets that yield broad flashes of light, while the pavilion facets are arranged to promote return light rather than light leakage, producing a pleasing mix of large flashes and small scintillating pinpoints. The girdle appears consistent and suitable for secure bezel or prong settings, and the overall proportions are compatible with a fine jewelry rendition that will sit comfortably in a ring head or pendant cup. This degree of craftsmanship yields a stone that photographs well and displays lively movement in natural and artificial light, characteristics that are particularly attractive to buyers who appreciate technical execution as much as aesthetic appeal.

Color and clarity are central to this sapphires character. The hue reads greenish yellow with an intense color intensity that translates as a vivid, richly saturated presence at face up viewing distances. When rotated under direct light the stone reveals subtle pleochroic effects with warmer yellow facets and cooler green flashes, an effect that enhances perceived depth and gives the gem an engaging dynamic quality. Clarity is graded as eye clean when evaluated at normal viewing distance, indicating that there are no inclusions visible to the unaided eye that would detract from the gems apparent purity or its optical performance. The sapphire has been heat treated, a stable and widely accepted enhancement used to refine hue and clarity. Origin is Montana, which informs both the gemological character and provenance narrative, and supports the stones individuality within the spectrum of natural sapphires.

This Montana greenish yellow sapphire makes a striking gift for someone special both for its measured technical excellence and for its emotional resonance. The combination of an intense greenish yellow hue, eye clean clarity, and precise mixed brilliant cutting creates a gem that reads as modern and refined when set in a minimalist solitaire, and as lively and expressive when surrounded by white diamond accents in a halo or trilogy design. For a wearer who appreciates technical detail, specify a mounting that showcases the gem table and allows side lighting to reveal the pleochroic play, or choose a low profile bezel for everyday wear that still preserves the stones optimized light return. At The Natural Sapphire Company we pair gemological accuracy with fine finishing and can advise on metal choices and setting designs that protect the stone while maximizing visual impact. Presented in a secure box with our documentation, this sapphire functions as both a technically excellent collector piece and as an emotionally resonant gift that will be admired for years.
