Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.14 carat blue sapphire in a mixed-cut rectangular cushion, from Sri Lanka (Ceylon), completely unheated, with an AGCL Gemstone Report (#M263769) confirming species, weight, dimensions, and unheated status. At 1.14 carats in a cushion, this Ceylon blue sits in the most consistently demanded center stone configuration in the sapphire engagement market — cushion-cut Ceylon blue above 1 carat in unheated quality. The cushion cut concentrates the blue saturation across the face, and unheated status preserves the natural color that made Ceylon the benchmark origin for fine blue sapphire.
Expert Opinion
Ahmed Shareek's Assessment
"This is a lighter, softer expression of Ceylon blue rather than the deep royal tone most buyers picture first — and that's exactly its appeal. The cushion cut opens the face and lets the color read bright and even rather than dark, which is what unheated light-blue Ceylon stones do best. At 1.14 carats with no heat treatment, it's an honest, well-proportioned stone that wears beautifully in daylight."
Rarity Analysis
Most of the blue sapphire market skews toward heated stones and toward medium-to-deep color saturation. This 1.14 ct stone sits outside both of those defaults — a light-toned, unheated Ceylon sapphire with independent lab documentation. Here is how the specification breaks down:
-
Color: light blue is a distinct segment from intense/vivid blue — softer and more pastel in character, appealing to buyers who want a brighter, daytime-friendly blue rather than a dark, saturated tone
-
Size: at 1.14 ct, a solid center-stone weight that comfortably clears the 1-carat threshold buyers commonly look for
-
Treatment: unheated — no thermal enhancement, which is the minority of blue sapphires on the market and the specification serious collectors prioritize
-
Clarity: Eye-clean, with no visible inclusions under normal viewing
-
Documentation: AGCL Report #M263769 confirms species, weight, dimensions, and unheated status; origin (Sri Lanka/Ceylon) is stated directly by Crescent Gems rather than listed among the items the report itself confirms
-
Combined effect: an unheated, lab-documented, above-1-carat Ceylon sapphire in a lighter color tone is a narrower slice of an already limited unheated-sapphire supply — genuinely uncommon rather than simply "rare" as a marketing label
Buying Guidance
A few things are worth weighing before buying this particular stone:
-
Color expectations: confirm that a light blue tone — rather than a deep or vivid blue — is what you want; this stone will read bright and airy, not dark and saturated
-
Setting choice: a lighter-toned stone can be set to either soften or intensify its color depending on the metal and halo/side-stone choices, so it's worth thinking through the setting before committing
-
Documentation on hand: the AGCL Report #M263769 travels with the stone and is worth keeping with your records and any future insurance appraisal
-
Custom setting timeline: if this stone is destined for a ring, build in time for a custom setting to be designed and made around it
