5.10 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 5.10 carat oval blue sapphire from Ceylon offered by The Natural Sapphire Company stands apart from the common market selection because it combines size, clarity, color and cut in a way that few stones at this price point achieve. Measuring 10.67 by 8.05 by 7.05 millimeters, this transparent gem presents a medium intense blue that captures the vivid Ceylon character without veering too dark or too pale, making it more wearable and versatile than many intensely saturated stones that can appear black under certain lights. The mixed brilliant cut optimizes light return and scintillation, delivering more fire and life than many standard step or shallow oval cuts, and the excellent polish ensures those facets act as tiny mirrors. At the eye level this sapphire is graded very very slightly included, meaning it reads near clean to the naked eye, a clarity advantage over the more commonly seen included Ceylon sapphires and a quality that rivals some of the more costly Burmese pieces while still remaining excellent value. The enhancement is clearly disclosed as heat treated, a stable and widely accepted practice that improves color and clarity without compromising long term durability, and that transparency about treatment is itself a market advantage when compared to undisclosed or unstable treatments common elsewhere.

Owning this sapphire is an investment in beauty and craftsmanship because its proportions, cut quality and origin combine to create a timeless piece that performs beautifully in fine jewelry while retaining collectible appeal. The oval shape flatters when set in a ring or pendant, and the 5.10 carat weight is substantial enough to make a statement yet practical for everyday wear, unlike many heavier stones that require awkward settings. From an investment perspective, a well cut, eye-clean, medium intense Ceylon sapphire holds resale desirability because collectors and designers prize the lively, nuanced blue associated with Sri Lanka and the documented treatment and origin enhance market confidence. From a craftsmanship perspective each facet was cut to maximize symmetry, brilliance and durability, reflecting the skill that The Natural Sapphire Company applies when selecting and finishing gems destined for heirloom pieces. If you are comparing options, this sapphire offers a superior balance of color, clarity, cut and size relative to many alternatives, making it a smart choice for someone seeking both immediate beauty and long term value.
