2.55 Ct. Greenish Blue Sapphire from Madagascar

This listing describes a transparent greenish blue sapphire weighing 2.55 carats, presented in an emerald cut with faceted styling, and measuring 8.98 x 6.52 x 4.23 millimeters. The stone exhibits medium color intensity, producing a balanced saturation that reads neither overly deep nor pastel, and allows both body color and internal character to be appreciated in most lighting conditions. Clarity is graded as slightly included at eye level, which indicates the presence of minor inclusions that are detectable on careful visual inspection but do not substantially impede light transmission or overall transparency. The cut is an emerald shape with step facets and trimmed corners, a geometry that emphasizes clarity and color distribution in this specimen. The surface finish is graded as excellent polish, yielding crisp facet junctions and a clean face up appearance. The sapphire originates from Madagascar, a notable source for corundum that can yield stones with attractive color ranges, and it has been enhanced by heat treatment, a stable and industry standard process used to improve color uniformity and clarity.

The emerald cut in this sapphire has been executed to balance length and width in a proportion that complements its 2.55 carat weight. Emerald cuts are defined by parallel step facets that create a hall of mirrors effect, favoring broad flashes of light over scintillation. In a stone with medium color intensity, the step cut allows the greenish blue tone to present evenly across the table, avoiding the appearance of overly concentrated color zones that can occur in deeper cuts. The slightly included clarity grade is consistent with the emerald cutting style, since step facets do not obscure inclusions in the same way that brilliant cuts can. However, the combination of transparent material, careful cutting, and excellent polish results in a gem that reads clean and attractive when set. Measurements of 8.98 x 6.52 x 4.23 millimeters situate this sapphire comfortably within common size ranges for rings, pendants, and other center stone applications, offering a substantial presence without excessive bulk.

Durability is a key consideration for any gemstone intended for regular wear. Sapphires are varieties of the mineral corundum and register a nine on the Mohs scale of mineral hardness. This value places them among the hardest gem materials available, second only to diamond, which rates ten on the same scale. By comparison, common jewelry materials such as quartz measure seven, topaz measures eight, and many beryls, including emerald, measure approximately seven and a half to eight but are frequently more prone to cleavage and surface-reaching inclusions. The Mohs nine rating signifies that this sapphire will resist scratching from most materials encountered in everyday activities, making it suitable for rings and other pieces that receive frequent wear. The stone will still require protection from sharp impacts and extreme force, as toughness and resistance to cleavage are distinct from hardness, but under normal use conditions the combination of a high Mohs hardness and a well executed emerald cut with excellent polish results in a durable and wearable gem. Heat treatment, the enhancement applied to this sapphire, is a stable and widely accepted method that does not materially compromise the inherent hardness of corundum, and it remains compatible with standard jewelry maintenance practices including gentle cleaning and routine inspections.

The provenance from Madagascar, the measured dimensions, and the specific attributes of this emerald cut greenish blue sapphire provide a clear profile for consideration by gemologists, designers, and buyers seeking a durable, transparent center stone with moderated color intensity. The slightly included clarity grade should be evaluated in context of the stone s face up appearance and the intended mounting, as certain settings can either obscure minor inclusions or place the table and pavilion where they are more visible. Settings that offer protective elements, such as a bezel, can enhance the long term durability of an emerald cut gem, while four prong or low bezel settings allow the emerald geometry to communicate its step facet aesthetic most directly. For those specifying a custom piece the excellent polish ensures that the stone will respond well to faceted display in both daylight and artificial illumination, and the greenish blue hue can be complemented by a range of metals and accent stones. The Natural Sapphire Company presents this sapphire as a clearly documented example of a heat treated Madagascar origin corundum, and it is offered with attention to accurate specification and practical guidance for setting and care.
