0.75 Ct. Yellowish Green Sapphire from Madagascar

This transparent 0.75 carat oval yellowish green sapphire, presented by The Natural Sapphire Company, combines measured proportions and artisanal cutting to create a collectible specimen suitable for a high end gemstone collection. The dimensions read 5.80 x 4.85 x 2.84 mm, yielding an overall depth of 2.84 mm relative to the mean diameter of 5.325 mm, which corresponds to a depth of approximately 53.36 percent, a proportion well suited to balanced light return and stable face up presence. The stone is faceted in a mixed brilliant style, with a brilliant cut crown above a pavilion that incorporates measured step facet elements, and the overall finish is described as excellent polish. The sapphire is of natural origin from Madagascar, it has received no enhancement, and its combination of untreated natural color, compact carat weight, and careful cutting make it an ideal acquisition for connoisseurs who seek specimens with both technical merit and visual appeal.

The mixed brilliant faceting strategy employed in this sapphire is executed to maximize both scintillation and color saturation, with a relatively large table facet calibrated to present the yellowish green hue evenly, and a pavilion designed to reinforce return of light through carefully aligned step facets. The transition between crown and pavilion facets is disciplined, with tight facet junctions and consistent facet angles that contribute to precise light partitions and micro scintillation across the table and crown. The oval outline is symmetrical, the girdle plane is consistent and suitable for conventional prong or bezel mounting, and the culet position and size have been controlled to avoid undue light leakage. The measured depth places the stone within a canonical range for mixed cut ovals, promoting a pleasing balance between brilliance and color depth, while the excellent polish ensures minimal surface diffusion of light so that internal optical phenomena remain crisp and well defined.

Color and clarity characteristics are central to the gem quality of this sapphire, and they have been evaluated with technical precision. The stone exhibits a medium color intensity, a dominant yellowish green hue that shifts subtly with orientation, consistent with pleochroic behavior commonly encountered in corundum where trace element balance influences the visible spectrum. This color is the result of natural trace element chemistry in the Madagascar material, and because the sapphire is untreated, the hue and tone remain original to the crystal, offering an authentic expression of its geological provenance. The clarity grade is very slightly included evaluated at eye level, indicating minor internal features that are visible under close inspection but do not materially impair transparency or the pathways of light within the stone. These inclusions are small and typically seated away from critical facet junctions, and their presence can serve as internal fingerprints that verify natural origin while preserving face up appeal.

From a collector and design perspective this untreated Madagascar sapphire offers a rare confluence of technical quality and wearable size that suits both investment grade cabinets and bespoke high end jewelry commissions. Its compact 0.75 carat weight and manageable dimensions make it ideal for a refined solitaire, a contemporary open halo design that allows light to pass through the pavilion, or an understated signet style where the natural yellowish green will be read as an elegant accent rather than an overpowering focal point. Given the excellent polish and the consistency of the facet work, mounting with a minimal bezel or four prong configuration will preserve brilliance while providing secure setting. Provenance from Madagascar and the confirmed absence of enhancement confer an added market premium, and when acquired from The Natural Sapphire Company this stone is offered with the assurance of accurate technical description, measured proportions, and confirmed treatment status, all of which are essential factors for the discerning buyer who values geological authenticity and cutting precision.
