0.52 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes a single transparent blue sapphire weighing 0.52 carat, presented in an oval outline with measured dimensions of 6.03 by 4.31 by 2.08 millimeters. The gem has been faceted to a mixed brilliant standard, a choice that balances scintillation from the crown facets with depth of color in the pavilion. Clarity is graded as very slightly included when evaluated at eye level, a practical grade that retains visual transparency while documenting minor natural characteristics. The color shows a dark intensity, yielding a deep, saturated blue, and the surface finish is noted as excellent polish, which contributes to a crisp, reflective appearance. This specimen has undergone standard heat treatment, an accepted enhancement that improves tone and uniformity, and it is sourced from Ceylon, Sri Lanka, a region renowned for producing sapphires with appealing cornflower and deep blue hues. The Natural Sapphire Company offers this stone as an example of classic Ceylon material, with precise measurements and treatment disclosure to support design and appraisal decisions.

Visually, the stone presents a compact face up area commensurate with its 0.52 carat weight, showing a rich blue that leans toward the darker end of the spectrum. The mixed brilliant faceting creates a play of light where smaller crown facets deliver sparkle while larger pavilion facets allow the inherent blue to register with depth and evenness. The very slightly included clarity means inclusions are present under casual observation for a trained viewer, but they do not detract from the overall visual appeal, particularly when mounted. The excellent polish ensures that light passes smoothly across facet junctions, enhancing the gem s luster and contributing to a lively response under ambient lighting. The measurements yield a modest table and a relatively shallow to medium depth proportion, making the stone suitable for settings that favor a low profile, such as bezels or low prong mounts, while still preserving optical performance and durability for everyday wear.

For pairing guidance in a custom piece, consider complementary gemstones that either contrast with or harmonize the sapphire s deep blue. Small white melee diamonds will provide a bright, high contrast halo or side stone motif, their white light return lifting the perceived saturation of the central blue. For a tonal scheme, pale blue sapphires or aquamarines placed as shoulders or accent stones will create a graduated transition from deep blue to light blue, producing a refined and cohesive color story. To introduce warmth, champagne or cognac diamonds will interact with the dark blue to create a vintage inspired palette, while green stones such as tsavorite garnets can supply a vivid complementary pop that emphasizes the sapphire s blue through color contrast. Pink sapphires or rubies used sparingly will create a lively triadic relationship and are well suited to bespoke pieces aimed at personalized color symbolism. Metal choice will materially alter perception, with white metals reinforcing coolness and brilliance, yellow gold imparting warmth to the overall composition, and rose gold softening the contrast for a more blended, romantic expression.

In practical design terms, this oval 0.52 carat Ceylon sapphire adapts to a range of settings and piece types, including solitaire rings designed for understated elegance, three stone rings where the side stones provide balance and proportion, pendant centers paired with a halo of small diamonds for focused brilliance, and drop style earrings where matched accents create movement and complementary color interplay. Given the measured depth and mixed brilliant cut, a low profile bezel or closed gallery prong setting will offer both protection and visual continuity, while an open prong or bezel with a polished foil or reflective back plate can be used selectively to enhance face up brightness. When commissioning a custom piece through The Natural Sapphire Company, consideration of accent stone size and spacing is important, because small melee should be scaled to maintain optical precedence of the central oval, and metal thickness should be chosen to protect the girdle and pavilion without overwhelming the delicate proportions. Detailed documentation of origin, weight, dimensions, cut description, clarity grade, polish, and enhancement will accompany the stone, supporting both aesthetic and investment minded decisions, and facilitating a bespoke design process that respects the sapphire s natural characteristics.
