6.77 Ct.Tw.Total Carat Weight Blue Star Sapphire Pair from Ceylon (Sri Lanka)

These two round star sapphires from The Natural Sapphire Company present a strong combination of classical asterism and collector quality gem characteristics. Each stone is a cabochon cut, the primary shape for displaying asterism, and they weigh 3.19 carats and 3.58 carats respectively, with dimensions of 8.53 x 7.96 x 4.37 mm and 8.60 x 7.90 x 5.10 mm. The cabochon profile and dome height are crucial because the star effect arises from oriented needle-like inclusions, primarily rutile, that intersect light to form a sharp star when the dome is proportioned correctly. These stones are translucent, which is consistent with classic star sapphire material where some diffusion of light enhances the visibility of the star rather than diminishing it. The reported clarity is very very slightly included, evaluated at eye level, which for star sapphires is an especially relevant assessment because many of the so-called inclusions are precisely the rutile silk that generates asterism. An educated buyer should note that asterism depends on the presence, quality, and orientation of those inclusions, and that an eye-level VVS reading in a star sapphire often indicates clean material aside from the beneficial silk, translating to a pleasing balance of brilliance and star contrast.

Color, polish, and enhancement status further define the value proposition of these stones. The sapphires are described as having a medium intense blue color intensity, a tonal range that is highly desirable for Ceylon material where the color tends toward a bright, lively blue rather than the very deep velvety tones of some other localities. Medium intense color paired with strong asterism can create excellent visual impact under directional light, producing a tight, mobile star that contrasts with the body color. The polish on both stones is graded excellent, which matters because the smooth, well-executed cabochon surfaces allow the star to appear crisp and mobile as the stone or light source moves. Importantly, these sapphires have no enhancement, meaning they are natural and untreated, a factor that significantly increases desirability and market value among connoisseurs and collectors who prioritize provenance and natural state. The pair is certified by Other, and their documented origin of Ceylon, Sri Lanka, adds further provenance weight since Sri Lankan sapphires are historically renowned for producing high quality blue material and for a distinct bright, cornflower to medium blue character that many buyers seek.

From a practical and investment standpoint these matched stones offer several advantages for the educated purchaser. The near matching weights and dimensions make them ideal for a matched pair in fine jewelry applications, most commonly as a pair of stud earrings or a coordinated pendant and ring set, where paired symmetry is visually important. When setting star sapphires it is essential to orient the cabochon so that the star is centered on the table and the dome height is sufficient to allow the light to intersect the rutile needles optimally, producing a six-rayed star that is sharp and well-centered, traits visible in high quality Ceylon star material. The absence of heat or diffusion treatments preserves the stones natural integrity, and for buyers concerned with long term value and collectability, untreated origin-documented sapphires typically appreciate better than those with enhancements. Care for these sapphires is straightforward but should respect their cabochon finish and silk content, favoring gentle cleaning with warm soapy water and avoiding harsh mechanical or chemical treatments; professional inspection is recommended if any setting work or resizing is planned to ensure the star remains centered and the cabochon integrity is unaffected. As with all premium gems, certification and provenance are key, and The Natural Sapphire Company is happy to provide further documentation, detailed photography, and advice on mounting options to maximize the display of asterism and long term value for collectors and purchasers alike.
