0.72 Ct. Blue Sapphire from Ceylon (Sri Lanka)

From the ancient riffles of Sri Lankan streams to the quiet precision of the lapidary studio, this blue sapphire carries a story that is as vibrant as its color. Mined in Ceylon, this gem began its life where volcanic and metamorphic forces fused aluminum oxide with traces of iron and titanium, creating the deep blue that has inspired kings and sailors for centuries. At 0.72 carat, and measuring 5.59 x 5.56 x 3.37 mm, this round shape stone concentrates that geological history into a compact, wearable jewel. Its mixed brilliant cut was chosen to balance fire and brilliance with the natural color distribution typical of high quality Ceylon material. The stone is transparent, with a clarity grade of very very slightly included, evaluated at eye level, meaning that under careful inspection you will find natural characteristics that confirm its authenticity without detracting from its visual appeal. The vivid color intensity gives the sapphire a rich, saturated blue that reads as luxurious and timeless, while the enhancement by heat treatment has been used to stabilize and enhance that hue, a widely accepted and permanent process within responsible gemology.

Once separated from matrix and rough, this sapphire was entrusted to skilled cutters who understood that Ceylon blue can be at once deep and lively, and that the right facet architecture will coax both facets and body color into harmony. The mixed brilliant cut combines a faceted crown that captures white light with a pavilion that returns color to the eye, yielding scintillation that works beautifully in both natural daylight and warm indoor light. The excellent polish ensures that each facet edge is crisp, allowing light to travel and reflect without interruption, which is especially important in a stone whose carat weight lives close to the finger. At 3.37 mm depth, the proportions have been calibrated to maintain face up size while maximizing optical performance, so that this 0.72 carat round feels larger than its weight alone might suggest, and it sits with an elegant presence whether mounted high or set low in a bezel.

The versatility of this sapphire makes it a superb candidate for a wide range of jewelry settings, and our designeers love to explore combinations that highlight its vivid blue tone. For a classic engagement ring, a simple four or six prong solitaire in platinum or 18 karat white gold will put the stone center stage, while a halo of small diamonds will add brilliance and perceived size without competing with the pure Ceylon blue. For those seeking durability and a contemporary silhouette, a bezel setting offers secure protection and a smooth profile that is ideal for daily wear. If you prefer something more ornate, consider a three stone ring with tapered baguette diamonds that accentuate the sapphire, or a vintage inspired setting with milgrain and filigree that evokes old world glamour. This sapphire is equally compelling as a pendant, where a low profile setting will allow the stone to catch light with every movement, or as a pair of stud earrings matched to a secondary sapphire or diamond pair, producing a refined yet vibrant color story.
