9.87 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This purplish blue, transparent sapphire from Ceylon Sri Lanka is a rare combination of size, color, and clarity that stands apart from the usual market offerings, and The Natural Sapphire Company presents it as a truly exceptional engagement gem. Weighing 9.87 carats and cut into an elegant oval, this gem measures 13.81 by 10.45 by 7.98 mm, and it is faceted in a mixed brilliant cut to maximize scintillation and depth. Compared with the many heat treated stones on the market, this sapphire is completely without enhancement, preserving its natural color and structural integrity. Its clarity grade is eye clean, evaluated at eye level, which means it shows no visible inclusions to the naked eye, a quality often reserved for much smaller or more costly stones. With medium color intensity and an excellent polish, the stone offers lively brilliance and color saturation that reads as sophisticated and versatile rather than overly dark or overly light, a balance that outperforms many commercial blue sapphires that can look flat or overly gray in certain lights.

For an engagement ring this sapphire is superior in both value and character, and it makes a compelling alternative to diamonds and treated sapphires for couples seeking something meaningful and enduring. At nearly 10 carats, the presence of this stone is immediate and memorable, yet its oval shape and mixed brilliant faceting allow it to sit comfortably in classic solitaire, halo, or three stone settings while delivering exceptional sparkle. The fact that it is unenhanced adds both rarity and long term value, especially when compared to the large proportion of sapphires that undergo heat treatment to improve color. Sapphires rate 9 on the Mohs hardness scale, second only to diamond, so this gem combines everyday wearability with heirloom potential. The purplish blue hue is unique among Sri Lankan sapphires, offering a romantic depth that flat blues cannot match, and the eye clean clarity allows the color to sing without distraction. Choosing this sapphire from The Natural Sapphire Company means choosing a natural, beautiful, and responsibly sourced center stone that will age gracefully and tell a story, making it an ideal and superior choice for an engagement ring that stands out for quality, value, and timeless appeal.
