This cushion shaped bluish purple sapphire weighs 1.81 carats and measures 6.65 by 6.23 by 4.73 millimeters, presenting a well balanced table to depth ratio that is suited to a variety of mounting styles. The mixed brilliant cut combines step facets with brilliant facets to deliver both depth and scintillation, and the excellent polish enhances facet junctions and overall light return. At this size and shape the stone offers a classic presence on the finger while remaining versatile for use in pendants and earrings, and its transparent body allows jewelers to work with light and setting geometry to emphasize either the stone's internal glow or its surface brilliance.
Color and clarity contribute to this sapphire's refined appearance. The tone sits in a bluish purple range with vivid color intensity that reads as saturated without appearing opaque, providing a rich, jewel like hue that responds attractively to different lighting conditions. The clarity has been graded as very slightly included when examined at eye level, meaning the stone is essentially clean to the unaided eye with small inclusions that do not distract from overall beauty. The stone has been heat treated, a stable and widely accepted enhancement for sapphires that improves color and clarity, and it originates from Tanzania, a source known for producing vivid and attractively colored sapphires. These technical attributes make the gem well suited for high quality, enduring jewelry designs where both visual impact and longevity are priorities.
Customization options for this sapphire are extensive, and the gem lends itself to many interpretations depending on design intent and lifestyle requirements. For an engagement ring a four or six prong solitaire will maximize light entry and show the cushion outline, while a halo of small brilliant diamonds will increase apparent size and add contrast to the bluish purple tone. A bezel setting will offer superior protection for everyday wear and will subtly frame the cushion shape, producing a modern or vintage inspired aesthetic depending on bezel thickness and finish. An east west orientation can create a contemporary profile that lengthens the finger visually, whereas a traditional north south orientation emphasizes depth and table face. For designs that emphasize sparkle, a low profile gallery with openwork will allow light to enter from multiple angles, and for pieces intended for frequent wear a slightly higher crown and secure prong shoulders will reduce the risk of contact at the girdle.
Beyond rings the stone adapts well to pendants, stud and drop earrings, and cocktail pieces. As a center stone in a pendant the dimensions provide a strong focal point without excessive weight, and a minimal bezel or prong cup will permit movement and light play. For stud earrings a matched partner could be sourced or the stone can anchor a complementary diamond halo to create balance and brilliance. For drop earrings the sapphire can be set as a primary element above smaller accent stones or as the lower focal gemstone paired with diamonds or colored sapphires for graduated color transitions. Metal choice will influence perceived color, with platinum or white gold offering a cooler backdrop that accentuates the bluish component, while yellow or rose gold will warm the presentation and can bring out purple undertones. Accent stones may include near colorless diamonds for brightness, small deep blue sapphires for tonal harmony, or contrasting gems such as pink sapphires and green tsavorites to create color juxtaposition.
Design and setting considerations should account for the stone dimensions and pavilion depth for optimal stability and light performance. The girdle proportions and the mixed brilliant cut facilitate secure prong placement, and a four prong head will show more table than a six prong head, which may be preferred where security and symmetry are paramount. For high impact designs a halo ring will visually increase table presence, and careful selection of halo stone size and spacing will preserve the cushion silhouette. For custom pieces The Natural Sapphire Company can recommend specific seat designs and protective features if the piece is intended for active daily wear. Heat treatment is stable under normal jewelry conditions, but standard care procedures should be followed, including periodic professional inspection of settings. Whether the end product is a minimalist solitaire ring, a vintage inspired cluster, a modern bezel pendant, or an elaborate cocktail ring, the stone’s weight, dimensions, cut and polish provide a robust starting point for achieving either understated elegance or dramatic presence.
Technical detail and collaborative design are available for clients seeking bespoke work, and The Natural Sapphire Company can provide guidance on metal choices, accent stone proposals, and setting mechanics to ensure the sapphire performs as intended in the finished piece. The stone’s 1.81 carat weight and cushion shape give it sufficient mass to be the visual anchor in a variety of compositions, while its vivid bluish purple color offers designers flexibility in pairing and finishing. For customers prioritizing everyday durability a bezel or low prong design in platinum or 18 karat gold will balance protection and beauty. For those seeking maximum color and light a minimal prong solitaire or a finely proportioned halo will amplify the visual impression. Our approach is to match design choices to the wearer’s lifestyle and aesthetic, ensuring that the technical attributes of the sapphire are used to their best advantage in the final setting.
