0.78 Ct. Bluish Green Sapphire from Madagascar

This listing describes one transparent bluish green sapphire weighing 0.78 carat, sourced from Madagascar and offered by The Natural Sapphire Company. The stone is fashioned in a round shape with a mixed brilliant cut, and it measures 5.08 by 5.04 by 3.76 mm. The color presents as a balanced bluish green with a medium intense saturation that reads equally well as blue with green undertones and as green with blue depth depending on light direction. Clarity is graded as slightly included when evaluated at eye level, allowing for clean visual performance at typical viewing distances while retaining natural internal characteristics that confirm its origin and authenticity. The polish is excellent, resulting in crisp facet junctions and lively surface reflection. The sapphire has been heat treated, a standard and stable enhancement for color and clarity that is fully disclosed, and the overall presentation is of a gem that combines natural character with technical finishing consistent with responsible gem handling.

The mixed brilliant cut is designed to optimize the balance between scintillation and color distribution, and at 0.78 carat the stone sits comfortably for use in fine rings, pendants, and bespoke settings where measured presence is desired. The pavilion depth of 3.76 mm and the near proportional crown and girdle plane support even light return, producing a pleasing pattern of facets that animate the bluish green body color. Slight inclusions are located internally and do not interrupt the gem s general transparency or detract from face up appeal, they serve as indicators of natural formation and aid in distinguishing this stone from synthetic or heavily treated alternatives. The medium intense color intensity allows for versatility in mounting metals and design choices, complementing both white and warm toned settings, and the excellent polish enhances optical clarity and wearability while reducing the likelihood of surface abrasion during setting.

When compared to sapphires from other renowned sources, this Madagascar gem displays a distinct identity, and the hue and tone can be contextualized against famous references. Kashmir sapphires are renowned for their rounded, velvety cornflower blue, a pure blue with a soft, almost powdered tone, whereas this Madagascar example introduces a pronounced green component that shifts the visual character toward teal and cool forest green at certain angles. Burmese sapphires from Myanmar often carry intense, saturated primary blue notes with a lively medium to strong tone, in contrast to the more muted and mixed bluish green presence of this stone. Sri Lankan, or Ceylon, sapphires can range from light pastel blues to vivid bright blues with a lively tone, they commonly appear lighter and more transparent in tone than this medium intense Madagascar sapphire which centers on depth and subtlety rather than brightness alone. Australian and Montana mines are noted for producing greenish blue and teal sapphires that share some kinship with this piece, however this Madagascar gem tends to present a slightly clearer, more medium intense saturation and a cleaner mixed brilliant cut, which gives it a different type of brilliance and color play. The combination of medium intense saturation, transparent clarity, and the balanced bluish green hue gives this stone a versatile aesthetic that sits between the cool, pure blues of Kashmir and Burma, and the greener, earthier tones sometimes seen in Australian material. The Natural Sapphire Company offers this sapphire as an example of Madagascar s capacity to produce gems with nuanced color relationships, and the stone will appeal to collectors and designers who seek a distinctive bluish green presence supported by sound cutting and honest disclosure.
