4.03 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent, cushion shaped blue sapphire weighs 4.03 carats and measures 9.55 x 7.74 x 5.42 mm, a size that offers a significant presence for a ring or pendant. The gem is cut in a mixed brilliant style, a combination that maximizes table brilliance and scintillation while preserving depth of color, and it has been given an excellent polish to enhance surface luster. Clarity is graded as very slightly included, evaluated at eye level, which means the stone presents as essentially eye clean to most observers while retaining natural internal character that confirms its natural origin. Color intensity is vivid, a highly desirable saturation that delivers a lively and deep blue, and the sapphire has been heat treated, which is a common and accepted enhancement to improve color and clarity. The origin of this sapphire is Ceylon, Sri Lanka, a provenance that is historically associated with some of the most sought after blue sapphires in the market, and this geographic attribution adds provenance value and collector interest.

For the buyer seeking a striking gift for someone special, this sapphire stands out both visually and materially. The combination of a substantial 4.03 carat weight, vivid Ceylon blue color, and expert mixed brilliant cushion cutting creates a stone that captures light and attention, making it ideal for an unforgettable engagement ring or a milestone gift. From a gemological perspective the very slightly included clarity and excellent polish contribute to everyday wearability and visual appeal, while the disclosed heat treatment aligns with best practice transparency for informed purchasers. At The Natural Sapphire Company we provide verified sourcing information and detailed grading so you can present this gem with confidence as a meaningful heirloom. Whether set as a solitaire to showcase its saturated blue, or framed by delicate side stones to accentuate fire and depth, this sapphire will convey thoughtfulness and refined taste, a timeless gift that combines natural rarity, skilled cutting, and responsible disclosure.
