0.64 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Whether you are searching for the perfect engagement ring that speaks of devotion, or you are a collector seeking a naturally beautiful specimen to add to a curated collection, your search can end with this fine blue sapphire from The Natural Sapphire Company. This gem weighs 0.64 carat, a weight that offers an ideal balance between presence and practicality, large enough to be noticed and admired, yet refined enough to suit elegant settings. The round shape and mixed brilliant cut are designed to enhance the gem face up, maximizing brilliance and scintillation so that each movement reveals lively flashes of blue. At eye level this sapphire is graded eye clean, which means the clarity does not distract from its beauty, and that combination of a clean appearance with a measured, pleasing carat weight is often what customers describe when they find the stone that truly completes their ring concept. Because it is entirely natural with no enhancement, this sapphire carries an authenticity that matters to discerning buyers, and because it comes from Ceylon, Sri Lanka, it brings with it a provenance associated with classic pastel and medium blue sapphires that collectors and brides alike prize.

Technically the stone measures 5.07 by 5.04 by 3.29 millimeters, dimensions that reveal a well proportioned round with a pleasing table size and depth, and a mixed brilliant cut that blends the best attributes of pavilion and crown faceting to strengthen fire and return. The 0.64 carat weight sits in an appealing niche between the more common half carat stones and larger three quarter carat pieces, which can translate into a refined look that is also cost effective for those who want significant face up presence without stepping into a substantially higher price bracket. The medium intense color intensity of this sapphire gives it a robust blue that remains versatile, appearing vivid under daylight yet retaining a softer, elegant tone under evening lighting. Excellent polish across the facets ensures that light travels without obstruction, creating crisp reflections and a lively overall appearance, and the eye clean clarity at normal viewing distances means that the gem reads as clear and pure to the naked eye, an important characteristic when a gem is destined for daily wear in an engagement ring or a treasured pendant.

When considering value and rarity, weight is a pivotal factor, and at 0.64 carat this sapphire occupies an especially attractive position. Smaller stones are abundant, and larger stones are rarer, but stones in this particular range that combine natural origin, no enhancement, clean clarity, and attractive color are comparatively scarce, and that rarity is reflected in the long term desirability of the piece. Unheated Ceylon sapphires, or sapphires with no enhancement, appeal to collectors and connoisseurs for their natural state and for the story they tell about geology and time, and when such a stone is also eye clean, it crosses a threshold from pretty to exceptional. The weight contributes to perceived value not only because carat is a direct pricing component, but also because at this size the sapphire reads distinctly on the finger, catching attention and anchoring design decisions, while still allowing for creative mounting options, such as delicate halos that increase apparent size, three stone designs that emphasize symmetry, or classic solitaires that celebrate the gem itself. As a piece inspected and offered by The Natural Sapphire Company, this sapphire comes with the confidence that its attributes have been carefully evaluated, and that the combination of 0.64 carat weight, mixed brilliant cut, eye clean clarity, medium intense color intensity, and no enhancement from Ceylon, Sri Lanka creates a collectible gem that is ready to become the centerpiece of your most meaningful jewelry.
