1.42 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.42 carat oval blue sapphire is a superb example of classic Ceylon color, with measurements of 7.04 by 5.34 by 4.07 millimeters, and a mixed brilliant cut that balances strong scintillation with a pleasing depth of tone. The material is transparent, showing a medium intense blue that is vivid without becoming too dark, and it has an excellent polish that gives the table and crown facets crisp reflection and lively return of light. Clarity is described as very slightly included when evaluated at eye level, which means the stone reads essentially eye clean to most observers, while still retaining natural internal character that confirms its authenticity. Importantly this sapphire has not been subjected to any enhancement, a distinction that places it in a rare and highly desirable category, and its origin from Ceylon Sri Lanka connects it to a long heritage of some of the world’s most respected sapphires. Presented by The Natural Sapphire Company, this gem is sized and shaped to perform beautifully as a central stone for an elegant solitaire, a refined halo setting, or a bespoke heirloom creation.

When compared to the broader market, this untreated Ceylon sapphire offers several advantages in quality, value, and uniqueness. Many sapphires offered today are heat treated to improve color and clarity, or they may be filled to mask fractures, and while those stones can be attractive, they are not the same as a fine natural sapphire that shows excellent material properties without modification. Synthetic sapphires and lower grade natural stones compromise either provenance or character, whereas this particular gem combines natural origin, eye level cleanliness, and a mixed brilliant cut that has been executed to enhance both brilliance and color saturation. In terms of size, a 1.42 carat oval with these proportions sits at an advantageous sweet spot for both presence and wearability, offering more visual impact than many 1 carat stones while remaining practical for everyday settings. The medium intense color is especially important, because it retains the bright, lively Ceylon blue that is unmistakable and more valuable than washed out or overly dark tones that dominate lesser material.

Value is not solely about the momentary spectacle of a gem, it is also about durability, rarity, and provenance, and this sapphire excels across those measures. Corundum, the mineral species to which sapphires belong, is one of the hardest gem materials, rated 9 on the Mohs scale, which makes it exceptionally well suited to daily wear and to being passed down through generations. Untreated sapphires from Sri Lanka are comparatively scarce in the global market, and collectors and families seeking a meaningful legacy piece understand that a natural, unenhanced Ceylon stone commands greater respect and stability in value than a treated alternative. The mixed brilliant cut further enhances long term desirability, because its faceting pattern is designed to maximize sparkle and surface appeal, making the gem read as lively and beautiful under a variety of lighting conditions. At The Natural Sapphire Company we prioritize sourcing gems that combine these attributes, and a stone that is both visually compelling and genuinely natural will always outlast fashion driven treatments in terms of appreciation and emotional value.

Turning this stone into a generational heirloom means more than simply mounting it and wearing it. The inherent qualities of this sapphire make it a perfect candidate for a design that will survive family trends, household wear, and the passage of time. An oval shape has enduring appeal, and its elongated silhouette flatters the finger and adapts to many setting styles, from classic four prongs that showcase the stone to protective bezel settings that guard the girdle while still allowing light to invigorate the table. Choosing a metal and setting style that complements the medium intense Ceylon blue will help maintain a timeless aesthetic, such as a platinum or 18 carat white gold halo for a refined look, or warm 18 carat yellow gold for a more traditional contrast that highlights the stone’s color. Inscription of a date or message on the mounting, combined with documentation of origin and treatment that we provide at The Natural Sapphire Company, will help future generations understand the story and value of the piece. The mechanical durability of corundum, together with a considered mounting and occasional professional maintenance, means this sapphire can be enjoyed daily for decades and then passed on as a living family treasure.

Practical care and provenance further support the claim that this sapphire is heirloom material, and make it an exceptional choice compared with more common or treated alternatives on the market. Routine care is straightforward, with gentle cleaning and occasional cavity checks by a qualified jeweler recommended to preserve the polish and secure the setting. Because this sapphire is untreated, its natural color will not shift with time or cleaning regimens the way some treated stones might, so the appearance your family enjoys today will be what future heirs inherit. From a provenance perspective, owning an unenhanced Ceylon sapphire from The Natural Sapphire Company offers both peace of mind and a story worth telling, because each facet of this gem speaks to authentic origin, careful cutting, and quality assessment. If your goal is to choose a center stone that will become a cherished heirloom, this 1.42 carat oval Ceylon sapphire provides the rare combination of visual beauty, structural resilience, and documented natural origin that distinguishes a piece designed to last through generations. If you would like advice on settings, metal choices, or legacy documentation, we at The Natural Sapphire Company are happy to guide you through creating a finished piece that honors this gem for decades to come.
