1.01 Ct. Bluish Green Sapphire from Madagascar

This oval shaped bluish green sapphire weighs 1.01 carat, and measures 5.88 by 5.73 by 3.54 millimeters, offering a classic oval spread that reads larger than its carat weight when set, and creating a substantial face up presence. The gem is transparent, with an intense color intensity that balances blue and green tones in a way that is vivid without appearing oversaturated, and it maintains exceptional clarity with a rating of very slightly included when evaluated at eye level. The cut is a mixed brilliant, a thoughtful combination of brilliant crown faceting and a pavilion arrangement designed to maximize light return, and the polish has been evaluated as excellent, creating glassy facet surfaces that allow light to enter and exit unimpeded. This sapphire is heat treated, a conventional and stable enhancement used to enrich tone and improve clarity, and it originates from Madagascar, a source known for producing sapphires with unique teal and bluish green nuances. These specifications make this stone an elegant and versatile choice for both classic and contemporary jewelry designs, and The Natural Sapphire Company stands behind the gem with transparent information about its origin and enhancement.

The sapphire owes its extraordinary sparkle to the intrinsic properties of corundum and to the precision of the mixed brilliant faceting. Corundum is a dense, crystalline form of aluminum oxide, and its tightly packed trigonal lattice produces a relatively high refractive index, which governs how strongly light bends as it enters the stone, and how effectively facets can capture and return that light. The gem also exhibits modest dispersion, which contributes to subtle fire, and a natural pleochroism, which means that different facet orientations emphasize slightly different color components when the stone is tilted. The cutter of this stone has used a mixed brilliant design to exploit these characteristics, placing smaller, well proportioned crown facets to break incoming light into intense flashes, and sculpting the pavilion facets to act as mirrors that reflect light back to the observer without leaking it out of the lower girdle. The measured depth and the oval proportions are balanced to promote scintillation across the table and along the length of the stone, creating a lively pattern of contrast and brightness that few step cut or poorly proportioned stones can match. The excellent polish reduces surface scattering, ensuring that every facet edge produces crisp light return, and the very slightly included clarity means there are minimal internal interruptions to the light path, allowing maximum brilliance and a clean, lively face up appearance.

When you compare this sapphire to other options on the market, it stands out across several key factors that affect both beauty and long term value. Many market stones offer strong color but are held back by heavy inclusions, dull polish, or generic cuts that fail to return light effectively. Others are eye clean but have weak saturation, making them appear lifeless in practical wear. This particular Madagascar stone combines an intense and attractive bluish green hue with an expert mixed brilliant cut and an excellent polish, a trio of qualities that is not commonly found together at this size. Heat treatment, when disclosed and expertly performed, is widely accepted by collectors and consumers because it stabilizes the beauty of the stone, while retaining a natural origin and robust physical properties. Compared to synthetic alternatives or lower grade material, this natural sapphire offers the durable hardness and provenance that enhance emotional and resale value, and compared to many commercially cut natural sapphires, the proportion and facet symmetry of this gem produce superior scintillation and a cleaner visual performance. The oval outline and the specific dimensions create an optical spread that competes with larger but shallower stones, giving you an immediate visual advantage in rings and pendants where face up presence is crucial.

Beyond technical superiority, this sapphire provides practical advantages for everyday wear and for special commissions, and The Natural Sapphire Company can guide you to settings that maximize its unique strengths. The gem is durable enough for daily wear due to the inherent hardness of corundum, and the mixed brilliant cut looks exceptional in solitaire settings that showcase the table and in halo settings that amplify color contrast while adding perceived size. Because the stone exhibits lively scintillation and a shifting bluish green play of color, it is particularly well suited to settings that leave the pavilion visible enough to allow light to enter from multiple angles, such as low profile four prong or bespoke bezel designs with open galleries. For buyers who are comparing value, this sapphire represents an optimal balance of natural origin, intense color, and superior cutting and finishing, and it is offered with full disclosure about enhancement and provenance. If you are seeking a gem that performs brilliantly in person, outshines many market competitors in both optical performance and craftsmanship, and comes from a respected source with transparent representation, this Madagascar bluish green sapphire from The Natural Sapphire Company is an outstanding selection.
