6.17 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 6.17 carat cushion shaped blue sapphire from Ceylon Sri Lanka presents itself as an exceptional choice for the discerning collector, combining rare size with classic color and expert cutting. Measuring 10.49 by 10.06 by 6.88 millimeters, this stone benefits from a mixed brilliant cut that maximizes return of light while preserving a broad, elegant face up appearance. Compared with smaller or more heavily included sapphires commonly found on the market, this gem offers intense color saturation without sacrificing clarity. Its clarity grade is very slightly included when evaluated at eye level, which means the inclusions are minimal and do not detract from the gem's striking visual impact, a distinct advantage over more included material. The excellent polish brings out crisp facet junctions and lively scintillation, giving the sapphire a combination of brilliance and depth that rivals higher priced stones from other sources. Heat treatment, disclosed and standard for many fine sapphires, has been applied to enhance color stability and uniformity, making this specimen both beautiful and consistent under varied lighting, and placing it ahead of untreated stones that may show uneven tones or absorbing inclusions that interrupt tenderness of color.

When compared to alternatives in the same weight class, this Ceylon sapphire stands out for its balance of value and provenance. Ceylon origin is well regarded for yielding vivid cornflower to royal blue tones that remain luminous rather than overly dark, and this gem exemplifies that heritage with an intense yet bright blue that photographs and performs superbly in jewelry. For collectors seeking a centerpiece that adapts gracefully to bespoke settings, whether a solitaire ring, a refined pendant, or a custom cluster, this sapphire lends itself to modern and vintage inspired designs thanks to its cushion outline and mixed brilliant facets. At The Natural Sapphire Company we prioritize stones that marry beauty with practical wearability and investment appeal. This sapphire offers a superior combination of size, color intensity, clarity, and polish when measured against common market offerings, making it an ideal addition to a high end gemstone collection and a smart acquisition for those who value both aesthetic excellence and long term desirability.
