1.55 Ct. Bluish Green Sapphire from Tanzania

This transparent 1.55 carat asscher octagon bluish green sapphire presents a rare and compelling combination of dimensions and optical quality, measuring 6.63 x 6.04 x 3.97 mm. The asscher cut retains the octagonal outline with stepped facets that emphasize clarity and depth of color rather than spectacle of dispersion, creating a restrained hall of mirrors effect that is highly prized by collectors who value precision and purity. This stone has been graded as very very slightly included when evaluated at eye level, meaning that any inclusions are minimal and do not detract from the gem when set and worn. The color intensity is recorded as intense, producing a rich bluish green that reads consistently across different lighting conditions, and the excellent polish enhances surface smoothness and light return so that the stone reads clean and lively to an educated eye. This sapphire is untreated, with no enhancement, a feature that materially affects both aesthetic integrity and long term value, and it is responsibly sourced from Tanzania. The Natural Sapphire Company will provide full documentation of the gemological characteristics and origin for your records, supporting provenance and long term stewardship.

From a gemological perspective this sapphire checks many of the boxes that discerning buyers seek. The asscher cut is a step cut, designed to showcase the inherent clarity and tone of a material rather than maximize fire, and with a clarity grade of very very slightly included the facet planes present without distraction. Untreated sapphires of this quality and intensity are comparatively rare on the market, and Tanzanian origins contribute to a documented provenance that collectors and institutions increasingly prefer. Corundum, the mineral family of sapphires, ranks nine on the Mohs scale, second only to diamond in everyday hardness, meaning that with sensible mounting and routine care this gem will withstand generations of wear without substantial degradation. The excellent polish and precise faceting further reduce microabrasion and help maintain brilliant surface condition, while the asscher form with cropped corners benefits from protective settings, such as a bezel or secure prong system, which preserve both beauty and structure over time.

When considering this sapphire as a generational heirloom, several factors make it especially suitable for passing down. The combination of one point five five carats, intense, stable bluish green color, eye level clarity assessment of very very slightly included, and the absence of treatments yields a balanced profile of rarity, durability, and aesthetic timelessness.
