4.21 Ct. Pinkish Purple Sapphire from Ceylon (Sri Lanka)

This pear shape sapphire presents as a transparent, well proportioned gemstone weighing 4.21 carat, with precise dimensions of 13.90 x 9.34 x 4.73 mm, and originates from Ceylon, Sri Lanka. The hue is described as pinkish purple with intense color intensity, a tone that reads richly across a range of lighting conditions. The cutter employed a mixed brilliant cut to balance scintillation and color saturation, and the stone exhibits an excellent polish that sharpens facet junctions and enhances overall luster. Clarity is graded as very slightly included, evaluated at eye level, meaning minor internal features are present but do not detract from the gem when viewed face up. The sapphire has been heat treated, a conventional enhancement that stabilizes and intensifies natural color and clarity, and this treatment is consistent with responsible trade practices for Ceylon sapphires. The Natural Sapphire Company presents this gem as a collector grade, yet eminently wearable, option for an engagement ring where color and presence are primary considerations.

From a gemological and lapidary perspective the mixed brilliant faceting is a deliberate choice for a colored stone of this size and outline. The mixed brilliant approach typically combines a brilliant facet arrangement on the crown with a modified pavilion that may incorporate broader, step influenced facets, and this geometry optimizes the balance between light return and color depth. For a pear outline with the length and width shown, the relatively shallow pavilion depth of 4.73 mm yields a broad face up presentation, which allows the intense pinkish purple hue to dominate the visual field rather than appearing concentrated in a small table. The result is a vivid, even saturation across the visible surface, with strong facet contrast that produces scintillation without fragmenting the color into patchy zones. Corundum pleochroism is evident in stones with mixed pink and purple components, and in practical terms this sapphire will show subtle shifts between pink and violet depending on viewing angle and light source, adding dynamic visual interest to an engagement ring design.

Clarity and finish are critical for an engagement gem intended for daily wear, and this sapphire performs well on both counts. The very slightly included grade at eye level indicates that inclusions are small, well healed, or positioned away from critical facet junctions, which preserves both strength and sparkle. The excellent polish enhances brilliancy and reduces surface wear from everyday contact, a useful characteristic for a ring that will be worn continually. Heat treatment was applied to enhance color and clarity in a stable manner typical of high quality Ceylon material, and there is no indication of surface reaching or resin filling in this example. From a setting perspective the pointed end of the pear is best protected with a V style prong or a tapered bezel, while the rounded end benefits from wider shoulder settings or a delicate halo to visually balance the weight and to protect the girdle area. Metal selection will influence perceived color balance, 18k yellow gold will warm the pink component and create a vintage inspired appearance, while platinum or 18k white gold will accentuate cooler purple undertones for a more contemporary expression.

As an engagement gemstone this sapphire combines substantial carat weight and resilient material properties with refined lapidary execution, making it an exceptional candidate for a centerpiece that is both beautiful and durable. At 4.21 carat the gem occupies a scale that commands presence without becoming impractical to wear, and the intense pinkish purple color delivers emotional impact that pairs particularly well with clean solitaire mounts or with precision halo settings that amplify color and perceived size. The textured play of color from pleochroism, the carefully handled mixed brilliant faceting, and the excellent polish translate into daily visual rewards for a wearer who appreciates nuanced gem performance. The Natural Sapphire Company can provide bespoke mounting options, independent laboratory reporting if required, and guidance on long term care including periodic professional inspections and routine cleaning with mild detergent and warm water. For a client seeking a technically sophisticated, yet emotionally resonant engagement gem, this pear shape Ceylon sapphire presents a compelling synthesis of craftsmanship, durability, and vivid color that will wear elegantly for a lifetime.
