1.59 Ct. Bluish Green Sapphire from Madagascar

This transparent, radiant shaped bluish green sapphire weighs 1.59 carats, a weight that places it in a category of stones that are both visually substantial and comparatively uncommon. The gem measures 6.62 x 6.42 x 3.62 mm, with a cut and proportioning that yield a pleasing table and pavilion balance. The radiant cut, characterized by its trimmed corners and faceted pavilion, enhances both scintillation and overall light return, and the excellent polish delivers crisp facet junctions and clean reflective planes. Color is intense, presenting a balanced bluish green tone that remains lively across different viewing angles, and clarity is graded as very slightly included, evaluated at eye level, which indicates minimal visible inclusions and a high degree of transparency. This sapphire originates from Madagascar, and it has been heat treated, a widely accepted enhancement that optimizes color and clarity while remaining stable over time. The Natural Sapphire Company includes this gem as part of our carefully documented inventory, with full disclosure of treatment, origin, and gemological attributes.

The weight of 1.59 carats is a primary determinant of both market value and rarity for this sapphire, and it should be considered in the context of color, clarity, and cut. Sapphires of this carat weight that exhibit intense color and transparent clarity are less common than smaller stones, and as carat weight increases, the rarity curve often becomes steeper. For gemstones of fine color, the price per carat typically escalates with size, reflecting the greater scarcity of larger clean material. In practical terms, a 1.59 carat sapphire occupies a bracket in which the visual impact is clearly greater than that of sub one carat stones, yet the gem remains versatile for a range of jewelry settings. The dimensions and 3.62 mm depth produce a depth proportion of approximately 55.5 percent when measured against the average of the length and width, a proportion that indicates efficient material retention during cutting, and that proportion contributes to both the perceived face up size and the stone's ability to exhibit its intense color without appearing overly deep or shallow. Taken together, the carat weight and proportions speak to both desirability and a relative rarity among sapphires in this tonal range and clarity grade.

Clarity, polish, and cut quality interact with carat weight to determine optical performance and market perception, and this sapphire presents a combination that supports its valuation. The clarity assessment of very slightly included, completed at eye level, means that inclusions do not significantly impair transparency or brilliance when viewed without magnification, and that condition supports strong light transmission through the pavilion facets. Excellent polish amplifies facet crispness, allowing for defined flashes and balanced reflection patterns across the radiant pavilion and crown. The radiant cut in this instance was executed to promote scintillation while preserving as much weight as practical from the rough, a balancing act that enhances overall value by maintaining both carat weight and optical appeal. Color intensity is described as intense, which signals saturation and chroma that are above average for many commercial sapphires, and the bluish green hue concentrates in a way that reads as uniformly lively under daylight equivalent lighting, further enhancing visual impact for the stated carat weight.

Origin and treatment are material facts that inform rarity and long term value, and for this sapphire both attributes carry relevant considerations. Madagascar is recognized for producing sapphires that range across a broad color spectrum, including distinct bluish green material that can display strong saturation and clarity. Heat treatment, disclosed here, is a stable enhancement commonly used to refine color and clarity, it is fully accepted by reputable trade and gemological practice, and it should be considered in any valuation or purchasing decision. The combined attributes of 1.59 carats, intense bluish green color, very slightly included clarity at eye level, radiant cutting, excellent polish, and Madagascan origin create a gem that is materially rarer than smaller or less saturated examples, and that rarity is directly reflected in market demand and price per carat. The Natural Sapphire Company documents each of these characteristics for transparency and verification, and our description is intended to provide a clear, technical account of how weight and gemological properties contribute to this sapphire s overall quality and standing among comparable stones.
