2.11 Ct. Green Sapphire from Madagascar

This round green sapphire weighs 2.11 carats and exhibits precise proportions at 7.21 by 7.29 by 4.85 millimeters, dimensions that translate to a depth ratio of approximately 66.9 percent, a proportion that contributes to the gem s ability to pool color and create a luxurious, velvety appearance. The cutting style is a mixed brilliant, executed to balance scintillation and color depth. The crown employs a traditional brilliant faceting pattern to maximize light return and scintillation at the table, while the pavilion transitions into modified facets that deepen tone and create layered flashes of green as the stone is rotated. The result is a gem that reads richly in hand and on the finger, with precise facet junctions and symmetry that preserve optical performance across viewing angles. The polish is graded excellent, which means the facet surfaces are free from noticeable polishing lines and display a high degree of surface luster, enhancing both brilliance and the perception of transparency.

Color in this sapphire is the defining characteristic, described by our gemological team as intense in color intensity, with saturation that is evenly distributed across the stone. The hue sits squarely in the green range, with subtle complexity that may show slight bluish or yellowish modifiers depending on light source and viewing orientation, a trait that is common for gem corundum and appreciated by connoisseurs for its dynamic character. Because corundum has a refractive index in the range of 1.762 to 1.778, and a low birefringence, faceting and polish become critical to manifesting color and life, and this specimen has been cut to exploit those optical constants. The stone also displays pleochroic tendencies, with different green intensities visible along different crystallographic axes, which contributes to the sensation of depth and internal motion as the gem is exposed to natural daylight or artificial illumination.

Clarity is graded as very slightly included, evaluated at eye level, an assessment that indicates only minor natural inclusions are present and they do not materially interfere with the visual appeal or structural integrity of the stone. Under careful inspection you may observe minute pinpoint crystals or faint needle like inclusions that act as internal fingerprints, confirming the natural origin of the corundum and adding character without detracting from brilliance. The heat treatment disclosed for this sapphire is a standard, stable enhancement applied to many fine sapphires, particularly those from Madagascar, to refine color and reduce the appearance of certain inclusions. The procedure used is well established within the trade, resulting in a permanent and stable improvement to the stone s color and transparency when performed responsibly. Our documentation and grading reflect this treatment, and the combination of natural origin, minimal inclusions, and expert heat enhancement yields a gem that is visually striking and fit for fine jewelry settings.

From the perspective of long term admiration and wear, this Madagascar green sapphire will continue to captivate for decades owing to several intrinsic and technical attributes. Corundum rates nine on the Mohs hardness scale, second only to diamond in common gem materials, and when set and cared for appropriately it resists abrasion and surface damage that would otherwise dull brilliance. The excellent polish and well executed mixed brilliant faceting ensure that light is efficiently returned through the crown, maintaining liveliness and color saturation even as trends in style evolve. Over time the stone will develop the kind of patina in its mounting that complements its depth of color and character, while the underlying optical properties remain unchanged. At The Natural Sapphire Company we select and present each gem with these considerations in mind, recommending settings that protect the girdle and pavilion to preserve faceting integrity, and advising on periodic professional cleaning to remove surface oils and residues that can temporarily mute luster.

In summary, this 2.11 carat round green sapphire from Madagascar is a technically sophisticated gemstone that brings together precision cutting, a deliberate depth ratio, intense color intensity, and excellent surface finish. The mixed brilliant cut has been tailored to exploit corundum s optical constants, producing balanced scintillation and color depth, while the very slightly included clarity affords confidence in both appearance and durability. Heat treatment has been applied in a controlled manner to enhance tone and remove distracting features, yielding a stable and visually compelling result. For buyers who value the intersection of craftsmanship, gemology, and timeless natural beauty, this sapphire represents a refined choice that will retain its visual appeal and continue to captivate over years of wear and appreciation, a jewel that we at The Natural Sapphire Company are proud to offer.
