24.93 Ct. Greyish Blue Star Sapphire from Ceylon (Sri Lanka)

This translucent 24.93 carat round greyish blue star sapphire measures 14.64 by 14.35 by 10.99 mm, set in a classic cabochon cut, graded very slightly included at eye level, showing medium color intensity and an excellent polish, no enhancement, origin Ceylon Sri Lanka. The muted greyish blue hue and translucent body allow a clean six ray star to glide across the dome with clarity, making the asterism immediately readable without overpowering saturation. Compared with Kashmir sapphires, which are prized for a deep velvety cornflower blue and a plush, saturated tone that can obscure fine star definition, this Ceylon stone offers a lighter, airier presence that rewards close viewing with a distinct, centered star. Against Burmese examples that often present richer, denser blues and stronger saturation, this Ceylon star reads as more luminous and elegant, and against Australian material that tends toward darker, greenish blue tones and lower translucency, the Sri Lankan origin yields a cleaner, more refined star effect. Madagascar can produce vivid blue sapphires with bright color, but many high color stones from that region are heat treated, making an untreated Ceylon piece of this size and clarity rarer in the untreated market. Montana sapphires typically show steely or teal hues in smaller sizes, making this nearly 25 carat Ceylon star exceptional for both scale and the delicate greyish blue tone.

From a value and collector perspective, this star sapphire sits in a superior position, particularly because it is untreated and has documented Ceylon origin, two qualities that markedly increase desirability compared with many market alternatives. The combination of nearly 25 carats, cabochon shaping that maximizes the asterism, medium color intensity that balances brightness with depth, and very slightly included clarity yields a gem that looks impressive in the setting and holds long term market appeal. For buyers comparing provenance and look, Kashmir pieces command extreme premiums but are extraordinarily rare, Burmese examples can be darker and heavier in hand, and Australian stones rarely display the same crisp star against a luminous body. This Sri Lankan star offers a rare intersection of scale, natural condition, and visual refinement, and it is offered by The Natural Sapphire Company with the assurance of provenance and expert presentation. Prospective collectors and connoisseurs seeking a distinctive, naturally formed star sapphire will find this gem to be an outstanding choice for both display and investment.
