1.15 Ct. Bluish Green Sapphire from Madagascar

This item from The Natural Sapphire Company is a precisely cut, transparent bluish green sapphire weighing 1.15 carats, presented in an Asscher octagon outline. The faceting style is classical step cut, executed with an Asscher faceting scheme to emphasize concentric symmetry and mirror like flash. The measured dimensions are 5.80 x 5.38 x 3.94 millimeters, providing a compact but substantial presence for use as a central gem in fine jewelry. The cutting and finishing report lists the stone as faceted with an Asscher cut, clarity graded as slightly included at eye level, color intensity evaluated as intense, polish graded as excellent, and enhancement by standard heat treatment. The material provenance is Madagascar, a source known for producing sapphires with strong saturation and well distributed color zoning, making this specimen particularly desirable for collectors and designers who value traceable origin and consistent material quality.

The Asscher cut geometry on this sapphire demonstrates precise facet planning to accommodate corundum optics and to maximize both color and light return. The octagonal girdle outline and truncated corners create a compact table platform with a concentric arrangement of step facets on the crown and pavilion that produce a hall of mirrors effect when viewed face up. Given the measured depth of 3.94 millimeters relative to the average girdle span of about 5.59 millimeters, the stone exhibits a depth of approximately 70 percent of the average girdle diameter, a proportion that intentionally favors color saturation over extreme brilliance. Facet junctions are aligned to tight tolerances and facet planes are cut to angles that compromise between internal reflection and maintenance of the intense bluish green hue characteristic of this material. The excellent polish enhances facet contrast and produces a satiny to high luster across the crown and pavilion facets, while the symmetry and even facet distribution reduce windowing and ensure consistent visual performance under varied lighting conditions.

Clarity evaluation at eye level indicates slight inclusions, a common characteristic for natural sapphires and particularly for stones sourced from Madagascar. These internal features are minimal and do not materially impair the transparent appearance or the precise step pattern created by the Asscher cut. At face up orientation the stone maintains high transparency and deep color saturation, owing in part to the careful orientation of the rough during the cutting process to place inclusions outside of prominent facet planes where possible. The bluish green coloration registers as an intense tone and saturation, consistent with trace transition elements, principally iron with potential contributions from titanium, influencing the chromophore balance in the crystal lattice. The heat treatment applied is a conventional, controlled thermal enhancement performed to optimize the dispersion of color centers and to stabilize the hue, a widely accepted practice that improves visual appeal while maintaining the gemological integrity of the corundum. The Madagascar origin correlates with the microchemical signature and the typical crystal habit that permitted this efficient Asscher cutting plan.

In terms of wearability and design versatility this Asscher octagon sapphire is exceptionally adaptable, translating equally well into casual and formal settings. For everyday use a low profile bezel or rubover setting will protect the stone and present a clean geometric silhouette that complements modern minimalist jewelry. For formal and statement applications the Asscher step pattern reads elegantly within an art deco inspired bezel with a delicate halo of small melee stones or within a four prong solitaried frame that allows the concentric steps to interact with overhead light. The deep pavilion and intense color respond well to white precious metals, which emphasize the bluish component, and to warmer alloys, which can enhance the green tone for a more muted, vintage palette. The durability of sapphire, together with the excellent polish and precise facet symmetry produced by skilled cutters, makes this gem suitable for rings, pendants, earrings, and bespoke signet type designs. Every step in the handling of this sapphire from selection to cutting to final inspection adheres to The Natural Sapphire Company standards, ensuring that the piece arrives with documentation of its characteristics and with the practical versatility expected by discerning clients.
