23.24 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This cushion shape blue sapphire from The Natural Sapphire Company stands apart from the sea of commercial stones that flood the market because of a combination of size, color intensity, origin, and natural state that is exceptionally rare. Weighing 23.24 carats, and measuring 16.24 x 14.28 x 11.14 mm, this gem occupies a scale that most modern pieces rarely achieve without being assembled from multiple smaller stones. It is GRS certified for authenticity and origin, and originates from Ceylon Sri Lanka, a source renowned for producing sapphires with velvety, saturated tones. The rich Vivid Blue Royal Blue color has the depth and life that makes lesser stones appear flat or overly dark in comparison, and the mixed brilliant cut enhances both scintillation and color return in a way that many standard cuts cannot match. Unlike many commercial sapphires that undergo heat treatment or other enhancements to improve color and clarity, this sapphire is natural and untreated, and that purity of origin and condition significantly increases its rarity and long term desirability.

When buyers compare this stone to others on the market, the differences become immediate and tangible. Many stones of comparable size are heat treated, filled, or even assembled to mimic a larger weight, which compromises both transparency and value. Treated or fracture filled sapphires commonly show altered light performance, and their values are discounted relative to natural, eye clean, untreated stones. This gem is eye clean at normal viewing distance, which means that inclusions do not distract from its visual appeal, and the excellent polish reveals crisp facet junctions and lively brilliance. The mixed brilliant cut is a thoughtful compromise between maximizing depth of color and delivering sparkle, and it is particularly effective in a large pavilion that preserves saturation while allowing lively return to the viewer. A GRS report accompanies the stone, providing independent verification of color intensity, lack of enhancement, and country of origin, which creates a secure provenance that outperforms uncertified or laboratory only verified pieces when comparing long term collectible value.

Beyond immediate visual impact, this sapphire is structured to become a generational heirloom in a way that cheaper alternatives cannot match. Corundum is one of the hardest gem minerals with a Mohs hardness of 9, which means this stone resists scratches and retains its polish and form through decades of wear, making it ideal for a piece that will be worn and loved year after year. Because it is untreated and certified, its story and origin are preserved and can be handed down with confidence, avoiding the stigmas and depreciation that can afflict treated stones. The substantial weight and classic cushion silhouette lend themselves to many jewelry designs from a dignified solitaire ring to an elegant brooch or a pendant that sits proudly on a chain, and expert setting can protect the pavilion while showcasing the color and brilliance for generations. The Natural Sapphire Company can assist with bespoke settings that use traditional techniques and secure mounting, ensuring the mounting style is compatible with regular wear while remaining timeless rather than trendy, which is essential when crafting an heirloom that will be treasured by grandchildren and great grandchildren.

An heirloom is not only a beautiful object, it is a story of provenance, care, and continuity, and this sapphire delivers on all counts. The GRS certification provides documented proof of origin and natural status that future custodians will value, while our detailed records at The Natural Sapphire Company create an ownership history that enhances collectible appeal. With proper care, occasional professional cleaning, and a secure mounting strategy, this untreated vivid blue sapphire will retain its remarkable hue and luster, and because it is rare in size, color, and untreated condition, it has the potential to outperform ordinary gems in both sentimental value and market desirability. For anyone seeking a single stone that confidently combines visual drama, physical durability, and verifiable authenticity, this 23.24 carat Ceylon sapphire is a clear choice, and an investment in beauty and legacy that resonates across generations.
