3.10 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 3.10 carat cushion shape blue sapphire from The Natural Sapphire Company is a rare combination of size, clarity, and color that stands apart from many stones you see on the market, measuring 9.09 by 7.44 by 4.59 millimeters, exhibiting a mixed brilliant cut that balances scintillation and depth, carrying a clarity grade of very very slightly included evaluated at eye level, showing vivid color intensity and an excellent polish, and this gem has been heat treated and originates from Ceylon Sri Lanka. In a market crowded with heavily included stones, poorly cut material, and synthetic alternatives, this Ceylon sapphire delivers a transparency and saturation that reads as vivid and alive, rather than flat or murky. Compared with many commercially available sapphires of similar carat weight, this cushion shape appears larger on the finger because of its face up dimensions and pavilion proportions, and its mixed brilliant cutting style maximizes light return in ways that step cuts and shallow cuts simply cannot, producing lively fire and a rich blue that changes character in different lights without losing depth.

When customers compare this sapphire to other options on the market, several practical advantages become clear. Natural Ceylon sapphires are prized for their lively, cornflower to vivid blue tones, and while Kashmir and Burmese stones occupy the top echelons for rarity and price, a top quality Ceylon like this offers a superior balance of color, brilliance, and value, giving collectors and wearers a better long term proposition when judged by everyday beauty and wearability. Many stones of similar carat weight are sold with visible inclusions at sight, or with weak polish and mediocre facet symmetry that mute the color and sparkle. This sapphire’s very very slightly included grading evaluated at eye level means it is effectively eye clean, offering a clarity and presence that most trade sapphires do not match. Heat treatment in sapphires is a standard and stable enhancement that improves tone and hue in a way that is permanent and accepted by gemological labs and the trade, and because this stone was expertly cut and polished after treatment, the result is a gem whose face up color is both vivid and even, with an excellent surface finish that will hold its beauty even under regular wear.

Beyond its immediate beauty, this 3.10 carat Ceylon cushion sapphire has all the qualities that make a true generational heirloom, qualities that outlast fashions and trends. Sapphire ranks second only to diamond on the hardness scale, making it exceptionally resistant to scratches and abrasion, so a well set sapphire will withstand decades of daily wear and be there to pass down to the next generation. The combination of substantial carat weight, classic cushion silhouette, and eye clean clarity means this gem will read as a centerpiece whether set in a timeless engagement ring, a family signet, or a pendant that can be worn across generations. The stable nature of heat treatment means the color will not fade with time, and the excellent polish and precise cutting mean the stone will continue to display lively brilliance without rapid loss of surface quality. Compared with lab grown or mass market stones, a natural Ceylon gem carries provenance and geological story, small natural inclusions or internal characteristics that prove origin and natural formation and that contribute to the personal narrative families treasure. At The Natural Sapphire Company we provide guidance on settings and protective mounting choices, offering recommendations for prong counts, bezel accents, or low profile settings that preserve the life of the stone while allowing it to shine, and we help customers visualize how a sapphire of these dimensions will sit and age in different mounting materials. For collectors and families who want an heirloom that mixes enduring beauty, practical durability, and market respect, this cushion shape Ceylon sapphire is a superior choice to many alternatives, and it is precisely the kind of gem that will be celebrated and handed down for generations.
