Antique Style Bluish Green Sapphire Ring 0.67 Ct., 14K Yellow Gold

This ring centers a 0.67 carat asscher octagon sapphire, dimensions 5.05 x 4.54 x 3.33 mm, cut in a traditional asscher faceting style that emphasizes step facets and a crisply defined octagonal outline. The asscher cut deploys a concentric pavilion and crown of broad parallel facets that create a hall of mirrors effect when viewed face up, and achieving optimal contrast and light return in this geometry requires exact symmetry and tightly controlled pavilion angles, qualities evident in the excellent polish and precise facet junctions on this stone. The color presents as bluish green with medium saturation, a balanced tone that allows both the blue and green pleochroic components to be visible depending on viewing angle and light source, providing depth without tipping into overly dark tone, and the clarity is rated eye clean at typical viewing distance, indicating no inclusions that interrupt the stepped facet planes or the stone face up. Origin is Montana, a provenance that often yields sapphires with lively, cool greenish blue hues and stable crystal structure, and the face up dimensions paired with the asscher proportions give a pleasing spread on the finger while retaining strong internal reflections due to the cut geometry and superior polish quality.

Flanking the center sapphire are white tapered baguette diamonds, total weight approximately 0.08 carats, clarity graded VS1 to VS2, and color graded F, chosen to present a high color purity and minimal visible inclusions against the warm gold setting. Tapered baguettes are a step cut variant with truncated corners and parallel facet planes that sit comfortably against the asscher shoulders, their long facets providing a clean, linear contrast to the concentric step pattern of the center stone and reinforcing the ring axis. The diamonds are set in secure bar style mounts with metal rails supporting the long edges of each baguette, and the transition into the shoulders is engineered to reduce edge exposure while preserving optical alignment. The center sapphire is held in a four prong setting, each prong precisely placed at the asscher corners to protect the cropped corners characteristic of this shape, and the prongs are sized to embrace the crown girdle without masking the table, allowing light to enter while preventing lateral movement. The gallery and prong buttresses are reinforced with solid construction beneath the basket to distribute stress away from the girdle, and the metalwork at critical junctions is soldered and finished to resist deformation, providing confidence in day to day wear.

The entire ring is fabricated in 14K yellow gold, a choice that provides structural resilience and a warm contrast to the bluish green center, and the shoulders feature hand engraved detailing that is cut into substantial metal so the decorative work does not compromise structural integrity. Finishing includes a high polish on exposed surfaces and careful burnishing at prong tips and bar edges to eliminate sharp points that could catch, while internal contact areas receive controlled finishing to maintain consistent sizing and comfort. From a practical standpoint the combination of a four prong corner grip, bar set baguettes with end security, reinforced gallery architecture, and a durable 14K alloy results in a design that prioritizes gemstone security without sacrificing the optical attributes of the asscher cut. At The Natural Sapphire Company we document the sapphire dimensions, carat weight, color saturation, clarity observation, and diamond specifications for every piece, and our workshop standards include final security checks on all prongs and settings prior to shipment. This ring is engineered for frequent wear and for customers who appreciate measured technical detail, and we are available to provide additional close up imagery, mounting micrographs, or to discuss customized adjustments and long term care recommendations.
