1.23 Ct. Bi Color Sapphire from Madagascar

This 1.23 carat, emerald cut, bi color sapphire presents a compact yet substantive mass, the weight contributing directly to its market rarity and intrinsic value. At 6.71 x 5.39 x 3.40 mm, the proportions reflect a well executed balance between length to width ratio and pavilion depth, enabling an optimal conversion of material weight into visible presence. The emerald cut, with its elongated table and parallel step facets, emphasizes transparency and color zoning rather than brilliance alone, and this facet architecture allows the full 1.23 carat weight to be read visually as a significant face up area. Clarity is graded very very slightly included, evaluated at eye level, abbreviated V V S, which is an exceptional outcome for a bi color specimen, because inclusions in corundum often disrupt the clean presentation of two distinct hues. The excellent polish and precise facet junctions minimize light leakage, so the numerical weight is translated efficiently into perceived size and optical impact, enhancing both wearable appeal and price per carat.

The bi color nature of this sapphire is articulated with medium intense color intensity, the two hues presenting in controlled zoning that interacts predictably with the step cut geometry. Emerald cut sapphire architecture typically produces broad flash windows and facet planes that reveal pleochroic shifts when the stone is rotated, and in this example the medium intense saturation maintains color integrity across the crown, without the risk of a dark face up window that can sometimes arise in larger table designs. Heat treated enhancement has been applied to stabilize and intensify the natural color components, a conventional and permanent treatment when performed under controlled conditions, and it preserves the crystal clarity that supports the very very slightly included assessment. Origin from Madagascar situates this stone within a gemological context known for complex growth zoning and attractive color varieties, and the specific combination of provenance, color intensity, and transparency is rare. The 1.23 carat weight is significant in a bi color piece, because combined color zones and step cutting reduce the number of stones that can be cut to such dimensions while retaining both color distribution and high clarity, making this sapphire comparatively scarce in the market.

From a craftsmanship perspective, the execution of the emerald cut is technically precise, the parallel step facets on the crown and pavilion aligned to produce even facet echoing and symmetrical light return. The table facet is broad enough to show internal character, yet the pavilion depth of 3.40 mm relative to the overall profile mitigates excessive windowing and maintains sufficient internal reflection for saturation to be seen from standard viewing distances. The excellent polish indicates a surface finish free of significant polish lines or abrasion, which preserves both face up luster and the capacity for clean facet reflection under magnification. The girdle thickness and edge finishing are calibrated to balance durability with ease of setting, enabling secure mounting without unnecessary weight loss. In practical terms, the 1.23 carat mass gives the stone presence in ring settings intended for everyday wear, and the measured dimensions allow the gem to sit proportionally in gallery and bezel constructions, while the bi color effect provides dynamic visual interest when incorporated into two tone metal designs.

The Natural Sapphire Company stands behind the gemological integrity of this specimen, and the combination of weight, cut, clarity, and color makes it a collector level example of a transparent bi color emerald cut sapphire. The weight is not only a numerical attribute, it is a material statement that amplifies rarity when paired with medium intense color and very very slightly included clarity, evaluated at eye level. For buyers who prioritize technical merit and investment quality, this sapphire offers a rare confluence of step cut craftsmanship, controlled color zoning, and the substantive 1.23 carat weight that elevates both market value and visual impact. Detailed examination and certification will confirm the reported measurements, treatment history, and origin, and The Natural Sapphire Company can provide full documentation and guidance on optimal settings to showcase the stone while preserving its technical attributes and long term value.
