0.70 Ct. Green Sapphire from Madagascar

This transparent 0.70 carat oval green sapphire from Madagascar presents as a technically refined specimen, with dimensions of 5.53 x 4.11 x 3.62 millimeters, and a calculated depth of approximately 75 percent, a depth that reflects a cutter priority on weight retention while maximizing pavilion refractive return. The gem is fashioned in a mixed brilliant cut, combining a brilliant facet arrangement on the crown with a more structured pavilion design, an approach that enhances scintillation and dispersive flash in a stone with light color intensity. Clarity is graded slightly included at eye level, with small internal characteristics that do not compromise structural integrity, and that can play a useful role in authenticating the natural origin. The excellent polish and careful facet junctions yield crisp light return across the table and crown facets, producing a subtle balance between sparkle and the soft, cool green hue. Heat treatment has been applied, standard practice in the trade to stabilize and refine tone, and it is a stable enhancement that does not diminish the gemological value when disclosed. The Madagascar origin is notable for producing sapphires with clean crystalline habit and attractive, restrained coloration, and this example displays the provenance through its crystalline clarity and even facet pattern.

For generational use this sapphire is inherently suited to become an heirloom, first by virtue of corundum hardness nine, which provides exceptional resistance to everyday wear and maintains polish over decades when properly set and cared for. The stone’s oval outline and moderate table size make it adaptable to a range of classic settings, with bezel settings recommended to protect the girdle and crown in frequent wear pieces, and four or six prong settings recommended when visibility and light performance are prioritized. The slightly included clarity can be strategically oriented within a mounting to visually minimize inclusions, or left visible as a feature that testifies to the gem’s natural history. With routine professional cleaning, occasional repolishing by a qualified lapidary, and a secure mounting in durable metals such as platinum or 18 karat gold, this 0.70 carat green sapphire will hold its structural and aesthetic qualities for generations. The Natural Sapphire Company stands behind the technical assessment and sourcing of this gem, providing documentation of origin and treatment so that this stone can be passed down with confidence and provenance.
