Antique Style Greenish Blue Sapphire Ring 1.44 Ct., 14K Yellow Gold

This oval greenish blue sapphire weighs 1.44 carats, with precise dimensions of 7.84 by 5.57 by 4.12 millimeters, and it presents a mixed brilliant cut that marries a full brilliant crown with a modified pavilion geometry. The mixed brilliant arrangement increases face up brilliance while preserving depth of color, with pavilion facet angles calibrated to return light into the medium intense color saturation of the green blue body color. Clarity is graded as very slightly included when observed at eye level, indicating inclusions that do not disrupt scintillation or overall transparency, and the stone exhibits an excellent polish that enhances facet definition and contrast. The measured depth produces a depth proportion of approximately 52.5 percent, which sits within the optimal range for oval stones to balance brilliance and color intensity, while the table and crown facets are proportioned to optimize scintillation without overshowing the gem tone. The sapphire has been heat treated, a stable enhancement that improves color uniformity and is a standard, accepted practice in the trade. Origin is Montana, and that locality imprint contributes to the gem profile through its characteristic green blue hues and crystal habit typical of this provenance.

The mounting is crafted entirely in 14K yellow gold, selected to harmonize with the cool green blue of the sapphire by introducing a warm color contrast that intensifies perceived depth and richness. The design employs a four prong cathedral setting that lifts the oval gem slightly above the band, maximizing light entry from crown and pavilion while securing the stone with minimal metal intrusion. The shoulders and gallery are hand engraved with a fine pattern, including milgrain beading along the edges and open filigree in the gallery, which together reduce weight without sacrificing structural integrity and allow additional light to circulate beneath the pavilion. Finish quality is evident in crisp prong heads, uniform milgrain, and seamless transitions at the ring shank, all performed by experienced goldsmiths using traditional engraving gravers and high polish techniques to maintain longevity under daily wear. The choice of 14K gold balances durability and luster, while the prong architecture facilitates routine maintenance such as cleaning and checkups without complex disassembly.

The provenance and narrative of this Montana sapphire add considerable intangible and tangible value, drawn from both geological history and human craft. Montana sapphires form in alluvial placers and hydrothermal environments that encapsulate slow crystallization histories, which produce the distinctive greenish blue hues that collectors and connoisseurs seek. This specific stone, cut and polished to preserve its natural color and clarity, carries the story of mountain sediments and glacial transports that concentrated quality material, followed by the hands of cutters who oriented facet patterns to preserve color zoning and maximize brilliance. Heat treatment in this case is used to refine color distribution, it is a transparent enhancement disclosed to buyers, and it enhances market desirability while keeping the gem in a natural class. At The Natural Sapphire Company we document origin and treatment as part of our selection standards, and we pair provenance with exacting craftsmanship on the mounting to ensure that the gem is both visually compelling and technically sound.

For technically minded buyers this ring offers a precise combination of gem metrics and artisanal setting technique that supports both aesthetic and practical considerations, it is a gem with controlled depth and facet architecture for optimal light performance, a clarity grade that preserves transparency for face up brilliance, and a color body that benefits from Montana origin and mindful heat enhancement. The 14K yellow gold framework, the cathedral elevation, the four prong engagement, and the hand engraved details together serve to highlight the mixed brilliant cut without obscuring the pavilion escape of light, resulting in an engagement or statement ring that demonstrates both provenance and workmanship. The Natural Sapphire Company stands behind the documented origin, the disclosure of heat treatment, and the meticulous goldsmith work that completes this piece, making it suitable for someone who values technical gemology and enduring craftsmanship.
