5.18 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exquisite transparent blue sapphire weighs 5.18 carats, and offers classic oval proportions measuring 11.73 by 9.07 by 5.27 millimeters, a shape and scale that have been prized for centuries. Cut in a faceted mixed brilliant style, this stone strikes a harmonious balance between scintillating fire and rich color saturation, with a dark color intensity that evokes the deepest Ceylon sapphires featured in royal treasuries. The clarity is graded slightly included, evaluated at eye level, a feature that speaks to natural character rather than detracting from the gem, and the polish is excellent, allowing light to dance across each facet. Originating from Ceylon, the island that has supplied the world with legendary sapphires for millennia, and heat treated to enhance stability and color uniformity, this gem carries both the romance of history and the practical assurances collectors value. As a gemstone specialist at The Natural Sapphire Company, I can tell you that its hardness and resilience make it an ideal candidate for an heirloom piece that will be enjoyed across generations.

This sapphire adapts beautifully to a wide range of settings, and can be customized to reflect any personal aesthetic, from antique to minimal modern. Set in a classic four or six prong solitaire, the mixed brilliant cut will maximize brilliance and presence, while a delicate halo of diamonds will amplify perceived size and vintage glamour. For daily wear, a low profile bezel or rubover setting offers protection and a clean architectural look. Consider a three stone composition to symbolize past, present and future, or pair two matching cuts for drop earrings or a dramatic pendant. Metal choices such as platinum to enhance cool blue tones, 18 karat white gold for brilliance, or 18 karat yellow and rose gold to warm the palette, will each create a distinct mood. I am happy to work with you on bespoke sketches, CAD renders and setting options to realize an engagement ring, cocktail ring, pendant, pair of earrings or cufflinks that honors the sapphire's Ceylon heritage and timeless character.
