3.07 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 3.07 carat cushion shape blue sapphire from The Natural Sapphire Company is a standout choice for collectors and bespoke jewelry clients, C.Dunaigre certified for authenticity and origin, with dimensions of 8.25 x 7.48 x 5.32 mm, a mixed brilliant cut, and an eye clean clarity grade when evaluated at eye level. Its vivid Cornflower Blue color intensity and excellent polish give it a lively depth and velvety saturation that outshines many market examples of similar size, where stones often trade depth for darkness or display fewer optical benefits because of inferior cutting and polish. Origin Ceylon, Sri Lanka, is renowned for producing the classic cornflower tone that remains highly desirable, and the heat treatment disclosed on this stone is a stable and widely accepted enhancement that improves color without diminishing the gem quality. Compared to common commercial sapphires that may be heavily included, overly dark, or subjected to less stable treatments, this sapphire delivers superior transparency, color purity, and light return, making it an exceptional value for its carat weight and visual impact.

For custom design, this cushion mixed brilliant sapphire pairs exquisitely with several complementary gemstones and settings, allowing you to emphasize different style priorities. For a timeless engagement ring, a tight halo of fine white diamonds set in platinum or 18 karat white gold will amplify brilliance and maintain cool color contrast, while tapered baguette diamonds on the shoulders will elongate the finger and add architectural elegance. For a warmer, vintage inspired look, surround the sapphire with a halo of small rose cut diamonds and mount in 18 karat yellow gold, or add small padparadscha or peach sapphire accents to introduce a soft complementary contrast. For a bolder, colored palette, pair with small green emeralds or vivid tsavorite garnets for a lively complementary contrast, or use matching cornflower sapphires as side stones to preserve tonal unity. Practical design choices include a four or six prong head to showcase the mixed brilliant cut, or a subtle bezel for everyday protection while keeping the stone prominent. At The Natural Sapphire Company we can source matching accent stones, provide CAD sketches, and recommend metal choices and setting profiles to ensure the finished piece highlights this sapphire as the focal point, delivering a custom creation that outperforms many off the shelf alternatives in beauty, longevity, and collectible value.
