1.56 Ct. Green Sapphire from Ceylon (Sri Lanka)

This 1.56 carat cushion shape green sapphire exemplifies the careful balance of proportions and material quality that discerning buyers seek, offered by The Natural Sapphire Company. The gem measures 6.64 by 6.44 by 3.63 mm, and exhibits a mixed brilliant cut that optimizes both scintillation and color saturation. Clarity is graded as slightly included evaluated at eye level, a level of inclusion that is consistent with natural gemstones and that preserves excellent transparency and light transmission. Color intensity is vivid, and the sapphire presents a clean, lively green that remains stable across viewing angles. Polish is excellent, and the stone is completely natural with no enhancement reported, originating from Ceylon, Sri Lanka.

At 1.56 carat this sapphire occupies an important weight band for cushion sapphires, where rarity and market value begin to increase more rapidly than at smaller sizes. Carat weight has a geometric effect on volume, and the visual presence of a sapphire increases approximately with the cube of linear dimensions, so moving from a sub one carat stone to a 1.56 carat example produces a substantially larger face up presence and a distinct change in perceived value. In practical market terms, the price per carat typically rises at weight breakpoints, and a natural unenhanced 1.56 carat green sapphire from Ceylon, Sri Lanka, with vivid color and excellent polish, commands a premium over smaller or treated examples. The gem displays a mean diameter of 6.54 mm, and the depth of 3.63 mm translates to a depth percentage of approximately 55.5 percent. That proportion is within an optimal range for cushion shapes cut to a mixed brilliant schema, allowing efficient light return while retaining sufficient pavilion mass to enhance color saturation.

The mixed brilliant cut used in this cushion shape integrates a brilliant style facet pattern on the crown with a modified pavilion architecture to marry brilliance with depth of tone. On the crown, star facets and kite facets are calibrated to produce well defined scintillation and to break light into lively flashes without washing the green tone, while on the pavilion a combination of triangular and kite facets is arranged to avoid light leakage and to concentrate color in the face up presentation. The cutter has controlled facet junction quality and facet symmetry, as evidenced by the excellent polish and consistent light performance across the table and crown facets. Slight inclusions, visible at eye level under strong viewing conditions, do not interfere with the classic mixed brilliant effect, and in some cases they act as pinpoints that subtly animate the stone under movement. The balance of facet angles and pavilion depth yields a gem that reads larger than its millimeter dimensions might suggest, particularly because the mixed brilliant approach allows a favorable spread of table area relative to overall depth.

Provenance from Ceylon, Sri Lanka, contributes to both the gemological character and collectible appeal of this sapphire. Ceylon material is historically noted for lively, transparent stones with clear tone and saturation, and this green sapphire follows that signature with a vivid intensity and clean transmission. The absence of enhancement is especially significant, as unheated and unenhanced sapphires retain original crystal lattice features and present a purer record of geological formation, which collectors and technical buyers prize. From a setting and design perspective the 6.64 by 6.44 mm cushion profile offers versatile mounting options, and the weight of 1.56 carat makes the gem suitable for a central stone in a sophisticated engagement setting or as a focal element in a pendant where the natural color and mixed brilliant cut can be appreciated. When evaluating investment and long term value, consider the combined factors of natural origin, no enhancement, vivid color intensity, and a carat weight that sits above common mass market sizes. The Natural Sapphire Company stands ready to provide condition reports, high resolution imagery, and mounting guidance to help integrate this technically refined green sapphire into a collection or a custom jewelry creation.
