Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
3.19 carat cushion-cut blue sapphire, natural and unheated, measuring 8.07 × 6.79 × 6.32 mm, with strong brilliance across the cushion facets. The GIA report's Additional Results field reads "No Indications of Heating" — a finding about heat alone, and we make no claim beyond heat. GIA Report #2235949149 confirms species, variety, weight, dimensions, color, transparency, and cutting style. Geographic origin was not requested as part of this GIA report, so no origin opinion was ever issued; the Sri Lanka (Ceylon) origin noted below is our own sourcing record — we buy direct in Sri Lanka through our Colombo, Beruwala and Ratnapura offices — and is not a GIA origin determination.
Expert Opinion
Ahmed Shareek's Assessment
"This is a 3.19 carat cushion blue sapphire, and its GIA report reads 'No Indications of Heating' in the Additional Results field. The cut is doing the work here — a Modified Brilliant Cut crown over a Modified Step Cut pavilion, which is how cushions of this shape are usually cut for brightness. I show stones like this to clients who want to read the paper for themselves."
What the Report Records — and What It Does Not
-
Treatment: The GIA report's Additional Results field reads "No Indications of Heating", which is why this stone is described as unheated. That field records what GIA's tests detected about heat, and we make no claim beyond heat.
-
Color: The report's Color field reads "Blue" and its Comments field reads "None". We describe the stone as blue and claim no color grade and no trade color designation.
-
Weight and measurements: 3.19 carats, 8.07 × 6.79 × 6.32 mm, as recorded on the report.
-
Cutting style: The report records a Modified Brilliant Cut crown over a Modified Step Cut pavilion, on a cushion shape — a combination cushions and ovals are commonly cut with.
-
Clarity: Minor inclusions under 10× in our own assessment. GIA colored-stone reports carry no clarity grade, so this is our observation and not a lab finding.
-
Origin: Geographic Origin on the report reads "Not Requested", so no origin opinion was ever issued. The Sri Lanka (Ceylon) origin is our own sourcing record — we buy direct in Sri Lanka through our Colombo, Beruwala and Ratnapura offices — and is not a GIA origin determination.
Buying Guidance
-
Read the treatment field on the report: Whatever a listing says in prose, find the lab report itself and read the field that records heat. On this stone that is the GIA report's Additional Results field, and it reads "No Indications of Heating".
-
Understand what the origin claim rests on: This stone's Sri Lanka (Ceylon) origin reflects our own sourcing documentation — we buy direct in Sri Lanka through our Colombo, Beruwala and Ratnapura offices. GIA's report covers species, variety, weight, dimensions, color, transparency and cutting style, but does not include an origin determination, so the origin claim is seller-documented rather than independently lab-confirmed.
-
Compare color consistently: View sapphires under the same lighting conditions (daylight-equivalent and incandescent) before comparing color across listings.
-
Read the measurements, not just the carat weight: The GIA report records this stone's crown as Modified Brilliant Cut and its pavilion as Modified Step Cut, on a cushion shape. At 8.07 × 6.79 × 6.32 mm its depth is about 93% of its width, so more of the 3.19 carats sits below the girdle than a shallower cut of the same weight would carry face-up.
-
Try Before You Buy: We encourage you to view this stone in hand before committing. Reach out to arrange an in-person viewing or ask for additional photos and video under different lighting.
