1.61 Ct. Yellowish Green Sapphire from Madagascar

This sapphire is a transparent 1.61 carat cushion shape yellowish green sapphire, with exact dimensions of 6.61 x 6.00 x 4.02 mm, a mixed brilliant cut, a clarity grade very slightly included evaluated at eye level, intense color intensity, and an excellent polish. The stone is untreated, no enhancement, and its provenance is Madagascar. The yellowish green hue is balanced between warm yellow tones and cooler green tones, and the intense saturation gives the gem a vivid presence while retaining fine tonal variation across the crown facets. The excellent polish produces sharp facet junctions and clean facet windows, so reflections are crisp and small facet reflections are well defined. These combined attributes make this sapphire a rare example of an intense color, clean appearance at eye level, and a highly finished surface, traits that support both visual performance and long term resilience when set into jewelry.

From a cutting and proportions perspective the mixed brilliant cut on this cushion form is engineered to marry scintillation and color depth. The crown exhibits a brilliant style facet pattern that maximizes distributed light return and dynamic flashes, while the pavilion is optimized with modified step and brilliant elements to control color saturation and minimize light leakage. The measured depth at 4.02 mm relative to the mean diameter of about 6.30 mm produces a depth percentage of approximately 64 percent, a proportion that favors both face up brilliance and a robust table presence. The cushion outline with softly rounded corners works particularly well with a mixed facet architecture because the cushion silhouette permits a slightly larger table, which enhances the perceptible color and makes the stone read slightly larger on the finger than its carat weight alone would suggest.

This sapphire adapts to a broad range of mounting approaches, and its dimensions and cut inform specific technical recommendations. For use as a center stone in a ring, a four or six prong setting with prongs seated at the cushion corners will protect the girdle while showcasing the crown facets, and a low profile bezel or partial bezel can be specified for daily wear to guard the corners without deadening the brilliance. A halo setting with fine pavé diamonds will intensify perceived color by contrast and is ideal if you want to emphasize the yellowish green nuance, while a plain solitaire in platinum or 18 karat yellow gold will deliver maximum color saturation and a classic silhouette. For bespoke pieces such as pendants or earrings, matching cabochon shapes or open back bezel seats will enhance tonal clarity, and for left right matched earrings the cut uniformity and clarity grade make this material an excellent candidate, although exact matching requires selection of companion stones from the same rough or careful re cut planning.

Practical craftsmanship notes for setting and custom design are important when working with an untreated Madagascar sapphire of these proportions. The polished girdle and the well finished pavilion require a setting seat matched to the measured depth to avoid stress at the girdle, and a secure head should allow for slight contraction without pressure on the pavilion facets. When considering tension style mounts, allow for precise diameter tolerances and a dedicated stress analysis from your bench jeweler, because the mixed pavilion geometry must be accommodated to prevent undue contact. Metal choice affects perceived color, with warmer 18 karat yellow gold slightly enhancing yellow tones, and platinum or white gold bringing forward the green component for a cooler reading. The Natural Sapphire Company can assist with CAD visualizations, exact bezel and prong specifications, and bespoke design options including micro pavé shoulders, cathedral shanks, and integrated three stone layouts, ensuring the final piece reflects both the technical characteristics of the gemstone and the intended wearability.
