1.51 Ct. Bluish Green Sapphire from Africa

This exquisite bluish green sapphire from The Natural Sapphire Company is a transparent 1.51 carat emerald cut gem, with precise dimensions of 7.50 x 5.57 x 3.55 mm, intense color intensity, and an excellent polish. The clarity grade is very very slightly included, evaluated at eye level, which means the stone presents to the naked eye as exceptionally clean, while minute inclusions are only apparent under magnification and do not interrupt light flow or durability. The gem has been heat treated, a standard and stable enhancement used throughout the trade to optimize color and clarity, and it originates from Africa, a region known for producing sapphires with compelling teal to bluish green tones. For the educated buyer, these combined attributes mean you are acquiring a well proportioned, durable corundum, with a high polish and clarity profile that maximizes visual appeal and resale desirability.

The emerald cut is an especially informed choice for this sapphire, because its long step facets and broad table emphasize the stones color saturation and internal luster rather than relying solely on brilliant sparkle, creating a sophisticated, architectural light performance. Structurally, sapphire belongs to the corundum crystal family, with a trigonal lattice that confers exceptional hardness and a high refractive index, so light entering the stone is subject to strong refraction and internal reflection. In this particular stone the cutting proportions and excellent polish work together to create repeated internal flashes and a depth of color that shifts subtly with movement, producing a refined scintillation that is unmatched by many other gem species, and by many lower grade sapphires. The lack of cleavage in corundum, combined with the gems polished facet junctions, enhances durability, making this sapphire well suited to daily wear in rings as well as elegant pendant or stud settings.

As specialists in natural sapphires, The Natural Sapphire Company affirms that this stones combination of intense color, transparent clarity, precise emerald cut dimensions, and professional heat treatment make it a discerning purchase for collectors and connoisseurs. The gems optical behavior, rooted in its crystal structure and realized through skilled cutting and polishing, delivers a balance of fire, luster, and color saturation that educated buyers recognize as the hallmark of superior sapphire quality.
