1.64 Ct. Purple Sapphire from Ceylon (Sri Lanka)

This cushion shape purple sapphire from The Natural Sapphire Company is a study in proportion and presence, weighing 1.64 carat and measuring 7.94 by 6.36 by 3.57 mm, a silhouette that reads both classic and contemporary on the finger. The gem is transparent with intense color intensity, and its overall depth works out to approximately fifty percent, a sweet spot for a cushion that balances face up size with optical performance. Cut to a mixed brilliant style, this sapphire marries the scintillating pavilion and crown dynamics of brilliant faceting with the controlled color display of a mixed pavilion, producing a gem that is lively under varied lighting while holding even, saturated color across the table. Origin is Ceylon Sri Lanka, a historic source known for producing sapphires with lively tone and refined hue, and the stone is completely natural with no enhancement, a quality that matters for discerning buyers who prize untreated material and geological provenance.

The cutting and finishing reveal skilled lapidary technique, the mixed brilliant cut executed to emphasize both brilliance and color depth. On the crown, precise brilliant style facets create scintillation and a sparkling dispersion that animates the purple hue, while the pavilion faceting is calibrated to return light efficiently and to prevent undesired light leakage. The cushion outline is well proportioned, the rounded corners and soft shoulders maintained to produce a flattering spread on a ring mount, and the table is centered to maximize the gemstone s visual balance. Excellent polish indicates crisp facet junctions and bright facet windows, which translates to high luster and minimal surface disturbance when viewed in hand. The facet transitions and symmetry are intentional choices to harmonize sparkle with saturated tone, a trade off that the mixed brilliant approach handles well for a purple sapphire of this size and depth.

Color and clarity interplay for this sapphire are particularly noteworthy, with intense color intensity and a purple hue that exhibits both cool blue undertones and a warm red component, giving the stone a vivid yet nuanced personality. Unlike treated stones that rely on enhancement to amplify tone, this piece carries its intensity naturally, which allows collectors and couples to appreciate the original crystal chemistry and growth conditions responsible for its color zoning and saturation. Clarity is graded as very very slightly included and was evaluated at eye level, which means that any internal features are minute and do not detract from the gem s transparency or brilliance to the naked eye. The combination of very good transparency, clean eye level appearance, and intense color produces a gemstone that reads as both rich and lively, showing flashes of violet and blue depending on movement and light angle, rather than a flat or overly dark appearance.

For use as an engagement gemstone this cushion purple sapphire is an excellent choice, balancing wearability, symbolism, and aesthetic versatility. Sapphires rate nine on the Mohs hardness scale, which confers strong scratch resistance for daily wear, and the stone s dimensions and mixed brilliant cut lend themselves to a variety of settings from classic four or six prong solitaires to bezel mounts that emphasize the cushion form, and halo or three stone designs that enhance perceived size and add brilliance contrast. Platinum will accentuate the cooler, violet tones, while yellow or rose gold can warm and enrich the purple, and a low profile mounting will protect the pavilion without compromising presence on the finger. At 1.64 carat the stone offers a noticeable center without overwhelming a delicate hand, and its excellent polish and even saturation ensure it photographs beautifully for engagement announcements and endures in everyday life. The Natural Sapphire Company stands behind the gem s origin and natural state, and we can assist with recommended settings, secure mounting, and accompanying documentation to support the stone s attributes, making this cushion purple sapphire a technically refined and emotionally resonant option for an engagement ring.
