Antique Style Blue Sapphire Ring 0.43 Ct., 18K White Gold

This ring centers a transparent 0.43 carat oval blue sapphire, with precise dimensions of 5.70 x 3.84 x 2.42 millimeters, cut in a mixed brilliant style designed to maximize both face up color and light return. The mixed brilliant configuration pairs a brilliant style crown with a modified pavilion, creating optimized facet angles that concentrate blue saturation toward the table while preserving lively scintillation. The measured depth relative to the average of length and width is approximately 51 percent, a proportion consistent with strong light performance in oval mixed cuts, and the stone exhibits an excellent polish that enhances facet crispness and overall brilliance. Clarity is graded as very very slightly included, evaluated at eye level, indicating eye level integrity with only minor inclusions that do not detract from transparency or durability. Color is described as medium intense blue, with even saturation across the table and pavilion, and the sapphire is untreated, with no enhancement, preserving its natural color and internal character, origin Ceylon Sri Lanka.

The mounting is crafted entirely in 14K white gold, executed with delicate openwork and a secure prong crown that lifts the sapphire to maximize light entry through the pavilion. The gallery features skilled hand finished filigree and precise pierce work, allowing additional light to interact with the pavilion facets, while the shank tapers to a slim, wearable profile that balances presence and comfort. All prongs are hand set and finely tipped to protect the girdle without obscuring the stone, and the piece is given a high polish finish that complements the sapphire face up color. The Natural Sapphire Company sources this sapphire through a traceable and audited supply chain, prioritizing responsible mining practices in Sri Lanka, fair labor standards for miners, and community investment and mine rehabilitation programs to minimize environmental impact. This combination of measured gem proportions, untreated natural color, refined mixed brilliant faceting, and ethically sourced origin defines the technical and ethical attributes of the ring, appealing to knowledgeable buyers who value both gemological precision and responsible sourcing.
