Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
2.04 carat cushion blue sapphire, measuring 6.58 × 6.37 × 5.57 mm, accompanied by GIA Sapphire Origin Report #6233835339 dated 14 January 2026. The report records Color Blue, Transparency Transparent, Species Natural Corundum, Variety Natural Sapphire, two separate cutting-style fields, and an Additional Results field that reads No Indications of Heating. It gives Sri Lanka as the geographic origin, as an expert opinion.
Expert Opinion
Ahmed Shareek's Assessment
"This one is a 2.04 carat cushion, and it comes with a GIA Sapphire Origin Report whose fields you can read for yourself: color, transparency, the two cutting-style entries, geographic origin and Additional Results. I would rather you judged it from the report and the photographs than from anything I say about it, so ask me for more images and look."
What the Report Records
The limit of our own reporting. We report the fields GIA printed on this document. Where we add a view of our own, such as the clarity assessment, the setting advice and the cleaning preference, we mark it as ours.
Read it yourself. The report is reproduced in the images on this page, and GIA's own service at reportcheck.gia.edu returns the same fields against the report number. Check it there, and ask us for anything else you want to see before you buy.
Geographic origin. The Geographic Origin field reads Sri Lanka. In its Comments section, GIA prints: "Any statement on geographic origin is an expert opinion based on a collection of observations and analytical data." We print the field and the caveat together and add nothing to either.
Additional Results. The field reads No Indications of Heating. That is a finding about heat, and it is what we mean when we call this stone unheated.
Cutting style, two fields. The report gives the crown and the pavilion separately: Crown: Modified Brilliant Cut, and Pavilion: Step Cut. The crown carries brilliant-style faceting; the pavilion carries step-style faceting.
Clarity. We describe it as eye clean, and that is our own assessment rather than a report value, because a GIA colored-stone report carries no clarity grade.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
Read GIA Report #6233835339 against the stone. Check the report number, the carat weight, the measurements, the color, the transparency, both cutting-style fields and the Additional Results entry against the physical stone before you finalise the purchase.
-
Look at the whole face-up view. Ask us for more images and video and look at the whole face before you decide.
-
Plan the setting around the stone's proportions. A cushion outline has rounded corners. We would choose a setting that holds the girdle securely all the way round; that is our own recommendation.
-
Use the Try Before You Buy option if you would like to see the stone in hand before finalising the purchase.
Species Characteristics
The three values below describe corundum as a mineral species. They are not findings about this individual stone. GIA prints them in the Characteristics panel of this report.
- Mineral: Corundum
- Mohs hardness: 9
- Toughness: Excellent
Separately, this report prints September as the birthstone month. September belongs to sapphire, the variety, in every color.

Care
GIA publishes its own cleaning guidance for sapphire. We prefer warm soapy water and a soft brush to ultrasonic or steam cleaners, because we cannot see how a stone is held once it is set. That preference is ours, not a condition carried on the report.
- Clean with lukewarm water and mild soap using a soft brush
- Store separately to avoid surface contact
- Once it is set, take it off for heavy physical work
