1.12 Ct. Green Sapphire from Tanzania

This transparent 1.12 carat asscher octagon shape green sapphire from Tanzania presents a technically refined example of precision faceting and natural color. The measured dimensions are 5.50 by 5.08 by 3.80 mm, the cutting style is faceted with a classical asscher cut, clarity grade recorded as very slightly included when evaluated at eye level, color described with intense color intensity, polish graded excellent, and the stone is unenhanced. At The Natural Sapphire Company we prioritize provenance and cutting integrity, this example combines clean transparency with a concentrated green that reads lively face up and deep when viewed through the pavilion.

The asscher geometry relies on a concentric step faceting scheme on both the crown and pavilion, with a pronounced square table and trimmed octagonal corners that generate the signature hall of mirrors effect. The facet architecture, executed with precise symmetry and edge alignment, emphasizes large, flat steps that act as mirrors, producing broad flashes of green interspersed with narrow, linear scintillation as the gem is tilted. Given the dimensions, the depth ratio is approximately 0.718, or about seventy one point eight percent, a proportion that enhances color saturation and internal reflections while maintaining a crisp window through the table. The pavilion steps are balanced to return light into the crown facets, creating layered contrast between bright facet planes and darker cross facets, which reinforces the asscher style vision of geometric light play.

From a clarity and craftsmanship perspective, the very slightly included grade indicates minimal internal features that do not materially impede transparency or the stone s directional light performance. The excellent polish supports clean facet junctions, ensuring maximum specular reflection across the crown and pavilion planes. Because this sapphire is not enhanced, the intense green is wholly natural, a characteristic tied to its Tanzanian origin and the gem s intrinsic trace chemistry. The result is a gem that performs both as a technical showcase of asscher faceting and as a versatile center stone for fine jewelry, responding exceptionally well to open four prong or low bezel settings that allow the asscher table and step sequence to engage with ambient light.
