1.04 Ct. Greenish Blue Sapphire from Madagascar

This elegant cushion shape greenish blue sapphire weighs 1.04 carat, and measures 5.64 x 5.14 x 3.97 mm. The pavilion depth and crown geometry reflect a deliberate balance between color saturation and light return, with an overall depth of approximately seventy four percent relative to the average diameter. The stone is faceted with a mixed brilliant cut, employing a brilliant facet arrangement on the crown and a modified brilliant pavilion designed to maximize scintillation while preserving intense face up color. The facet junctions are executed with high symmetry, and the excellent polish ensures smooth facet planes that translate to crisp facet reflections and minimal surface disturbance. The girdle has been finished to industry standards, and the culet position has been controlled to avoid unwanted light leakage. This sapphire is entirely natural, no enhancement, and originates from Madagascar, a source that has produced many of the market s most vibrant and fine examples in recent decades. The Natural Sapphire Company provides this gem with full provenance documentation, emphasizing its untreated status and exacting lapidary work.

Optically this sapphire demonstrates the classical properties of corundum, with a refractive index in the range expected for gem quality sapphire, and enough birefringence to contribute to facet edge separation under critical viewing. The mixed brilliant cutting scheme produces a dynamic interplay between brilliance and color. The crown facets act to disperse spectral flashes and contribute to lively scintillation, while the pavilion geometry concentrates light back through the table to enhance the intense greenish blue hue. The color intensity has been graded as intense, meaning that the stone displays saturated color without appearing overly dark in standard illumination. Clarity is graded as very slightly included, evaluated at eye level, with inclusions that are minor and well positioned so as not to interrupt the overall pattern of light return. These inclusions do not affect the structural integrity or polish, and they serve as natural fingerprints confirming origin and natural formation. With a hardness of nine on the Mohs scale and robust crystalline structure, this sapphire is suitable for daily wear when set with appropriate protective considerations for cushion corners.

To place this stone in historical context, compare its characteristics to renowned sapphires that have defined taste and value over centuries. The Logan Sapphire and the Rockefeller Sapphire are celebrated for their intense color and exceptional size, and while this Madagascan cushion is modest in carat weight in comparison, it shares an affinity for saturated face up color that is prized in those museum pieces. The velvety blues of classic Kashmir sapphires are often referenced as the benchmark for hue and tone, and although Kashmir material is different in formation and often distinguished by a signature velvety texture, this stone s intense greenish blue recalls the depth and richness that collectors associate with those legendary examples. Sri Lankan Ceylon sapphires historically brought lighter lively blues to crown jewels, and this gem sits between those historic color typologies, offering a saturated blue base with a subtle green overtone that gives it a unique and contemporary personality. Madagascar has become increasingly recognized for producing untreated sapphires that rival historical sources in color intensity, and untreated status enhances provenance value, aligning this gem with the untreated historical stones that carry superior collector interest.

From a setting and collector perspective this sapphire offers a rare combination of attributes. The cushion outline, with softly rounded corners and compact dimensions of 5.64 by 5.14 mm, reads slightly larger than the carat weight might suggest due to efficient table proportions and optimized pavilion design. For settings the intense greenish blue will respond to metal choice, yellow gold will warm and emphasize greenish undertones, while platinum or white gold will preserve cooler blue characteristics and accentuate white light return. A well proportioned prong setting will allow maximum light interaction and display, whereas a bezel setting can protect the cushion corners and create a modern presentation. For collectors and investors the untreated origin from Madagascar, combined with excellent polish and a clarity grade of very slightly included evaluated at eye level, positions this sapphire as an object of enduring appeal and rarity. The Natural Sapphire Company stands behind the gem with detailed imagery and full disclosure of origin and enhancement status, and we can provide gemological documentation and mounted design options. For buyers who appreciate technical refinement, lapidary craftsmanship, and the subtle dialogue between historical precedent and modern provenance, this greenish blue cushion sapphire represents a distinct and technically compelling choice.
