At just over 1 carat, this Ceylon Blue Sapphire is a practical, wearable center stone weight for engagement rings, pendants, and everyday fine jewelry.
Expert Opinion
Ahmed Shareek's Assessment
"This 1.16 ct Ceylon blue is a genuinely vivid, saturated stone rather than the pale or overly dark blue you see too often at this size — heat treatment is standard practice for the vast majority of sapphire on the market, and it's what reliably brings out this kind of even, lively color. At just over a carat with eye-clean clarity, it's an easy, practical stone to recommend for a ring or pendant."
Rarity Analysis
Blue is the color most people picture when they hear the word "sapphire," and Ceylon (Sri Lankan) material has long set the benchmark for that color. Here is how this particular stone stacks up against that standard.
-
Color: A vivid, saturated blue from Sri Lanka — the most classic and widely recognized sapphire color, with broad, enduring demand across every market.
-
Size: At 1.16 ct, this stone is a practical, wearable center-stone weight — substantial enough to anchor a ring or pendant without requiring a custom mount.
-
Treatment: Heated — a standard, widely accepted practice for blue sapphire that is disclosed honestly here and does not reduce the stone's desirability.
-
Clarity: Eye-clean, with no inclusions visible to the naked eye under normal viewing conditions.
-
Documentation: Backed by an FGL (French Gemological Laboratory) report, which confirms this stone's weight, dimensions, color, and heat treatment. The Sri Lanka (Ceylon) origin stated here is presented as Crescent Gems' own sourcing information rather than a laboratory origin determination, since the FGL report does not address geographic origin.
-
Combined effect: A classic, well-cut Ceylon-sourced blue in a practical, wearable size with independent documentation is solid, dependable value — not a rare showpiece, but an honestly presented stone that delivers on the classic sapphire look.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
Confirm the setting fits the stone: At 7.50 × 5.52 mm, this oval will need a mounting sized to that footprint — check a prospective setting's stated stone dimensions before ordering, especially for a custom build.
-
Treatment is standard, not a concern: Heat treatment is normal for blue sapphire and is disclosed here — it is not a defect and requires no special care beyond normal handling.
-
Review the documentation: Request and review the FGL report directly to confirm the treatment and grading details match what's described here, and note that origin is presented as the store's own sourcing information rather than a lab finding.
-
Judge the color in different light: Blue sapphire can shift subtly between daylight and indoor lighting — view the stone, or its video, under more than one light source if possible.
-
Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.
