0.69 Ct. Green Sapphire from Madagascar

This oval green sapphire from The Natural Sapphire Company is a refined collector grade gem, weighing 0.69 carat and measuring 5.59 x 4.64 x 3.30 mm, presented in a classical oval outline that balances face up presence with comfortable wearability. The stone is transparent and has been fashioned with a mixed brilliant cut that unites a brilliant style crown with a faceted pavilion, a combination that optimizes both scintillation and depth of color. Its clarity is described as very very slightly included when evaluated at eye level, which for the trained viewer means that any inclusions are minimal and do not detract from the overall visual impact of the gem. Color is a medium intense green, a saturation that provides lively color without veering into darkness, and the polish has been assessed as excellent, ensuring that light passes cleanly into and out of the stone. This sapphire has undergone customary heat treatment to enhance color and clarity, a stable and widely accepted enhancement practice in the trade, and it is sourced from Madagascar, a region known for producing a broad range of sapphire colors with attractive natural zoning and character.

The defining technical strength of this gem lies in its geometric faceting, precisely laid out to maximize light play. As a mixed brilliant cut, the crown employs a series of triangular and kite shaped facets that direct light into the stone and break it into flashes of white light, which is the appearance commonly described as brilliance. The pavilion has been engineered with larger, well proportioned facets that control internal reflection, encouraging an efficient return of light through the crown rather than leaking light out of the pavilion. The oval shape introduces elongated facet alignment that enhances the perception of size and creates dynamic, linear scintillation as the gem moves. Symmetry and table proportions are critical for performance, and in this example the facets converge with consistent geometry, creating a lively interplay between broad flashes and fine pinpoint scintillation. The medium intense green color benefits from the cut because the facet angles allow both saturation and brightness to coexist, producing vivid face up color without loss of sparkle. In addition, green sapphires can exhibit subtle pleochroism, and the mixed brilliant faceting here allows an observer to perceive slight shifts in tone and depth as the stone is viewed from different angles, adding visual complexity that educated buyers often prize.

For the informed buyer evaluating value, this sapphire presents several appealing attributes that justify consideration. The 0.69 carat weight places it in a versatile size category for both bespoke jewelry and investment grade parcels, and the exact dimensions permit predictable bezel or prong settings without the need for extensive customization. The eye level clarity of very very slightly included denotes a clean appearance to the unaided eye, a desirable characteristic for stones intended to be set in rings or pendants where loupe level perfection is not a necessity for visual attractiveness. Madagascar origin contributes provenance, as stones from this source are respected for their range of natural hues and trace element chemistry, and the fact that the gem has been heat treated is both industry standard and a noncontroversial enhancement that is permanent when performed correctly, unlike surface treatments that require specialized care. From a design perspective, the geometric facet pattern and excellent polish make this sapphire particularly responsive to white metal mountings where contrast enhances brilliance, while yellow or rose metals can warm the green and emphasize olive or grassy undertones. Care recommendations are straightforward, with normal precautions for precious corundum including avoidance of harsh chemicals and ultrasonic cleaning if the stone is set in delicate antique settings, and routine professional checkups to ensure secure settings. When purchasing from The Natural Sapphire Company buyers gain access to provenance information and gemological documentation that supports confident acquisition, and the combination of measured dimensions, mixed brilliant faceting, excellent polish, and Madagascar origin offers a transparent, technically described gem that will appeal to collectors and connoisseurs seeking a green sapphire with both visual allure and sound gemological credentials.
