Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.29 ct unheated teal sapphire in a cushion shape. GIA Sapphire Origin Report #6247017788 records the crown as Modified Brilliant Cut and the pavilion as Step Cut, and the color as "Blue and Yellowish Green" — teal is our own trade term for that blue-green.
Expert Opinion
Ahmed Shareek's Assessment
"The GIA report on this 1.29 ct stone reads 'No Indications of Heating,' so it is unheated, and it records the crown as Modified Brilliant Cut over a Step Cut pavilion. GIA prints the color as 'Blue and Yellowish Green'; teal is the word we use for it in the trade. On origin the report gives 'Basalt Related' and names no country, and I am not going to put a country on a stone that the report does not."
What the GIA Report Records
Read off GIA Sapphire Origin Report #6247017788, dated August 03, 2026:
-
Species / Variety: Natural Corundum / Natural Sapphire
-
Weight: 1.29 carats
-
Measurements: 7.56 x 5.93 x 3.57 mm
-
Shape: Cushion
-
Cutting Style: Crown: Modified Brilliant Cut / Pavilion: Step Cut

Geographic Origin: Basalt Related. That is a finding, not a blank — the report names a geological origin for the stone even though it does not name a country, and GIA states that it could not determine a specific country. GIA prints: "Any statement on geographic origin is an expert opinion based on a collection of observations and analytical data." We add no sourcing claim of our own.
-
Additional Results: No Indications of Heating — a finding about heat, which is why this page says unheated and nothing wider.
-
What the report does not carry: GIA colored-stone reports give no clarity grade, no cut grade and no color grade. The Loupe Clean clarity and the teal color name used on this page are ours, not GIA's.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
View it in more than one light source. A stone GIA records as "Blue and Yellowish Green" can read nearer the blue or nearer the green depending on the lighting — check the stone (or the video on this listing) under both daylight and indoor lighting before deciding.
-
Plan the setting around its cushion outline. GIA prints the measurements as 7.56 x 5.93 x 3.57 mm, so the outline is longer than it is wide — that comparison is ours, read off those two figures — and a setting made for that outline will suit it.
-
Ask any seller for the treatment finding on the lab report itself, not only in the listing copy. On this stone the GIA report reads "No Indications of Heating."
-
Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.
