3.19 carat cushion-cut deep blue sapphire, natural and completely unheated, measuring 8.07 × 6.79 × 6.32 mm. Rich, saturated deep blue with strong brilliance across the cushion facets. Unheated and untreated: the color is entirely natural with no thermal modification of any kind. Accompanied by GIA Report #2235949149 confirming weight, dimensions, color, transparency, and unheated status. Geographic origin was not requested as part of this GIA report; the Sri Lanka (Ceylon) origin noted below reflects our own sourcing documentation rather than a GIA origin determination.
Expert Opinion
Ahmed Shareek's Assessment
"A 3+ carat unheated blue sapphire with GIA confirmation is something I see far less often than you'd think — most stones this size have been heat-treated to improve their color, so finding one this deeply saturated that never needed the furnace is genuinely uncommon. This is a stone I'd set aside for a client who wants the real, untouched thing."
Rarity Analysis
-
Treatment: The overwhelming majority of commercial blue sapphire on the market today is heat-treated to enhance color and clarity. This stone is unheated, and GIA Report #2235949149 confirms that unheated status directly — at over 3 carats, natural-color unheated blue sapphire is a genuine rarity, not a marketing phrase.
-
Color saturation: A deep, richly saturated blue achieved with no thermal treatment is harder to source than a comparably colored heated stone, since heating is often what pushes lower-grade rough into a marketable blue.
-
Size: At 3.19 carats, this stone is well above the size at which most natural, unheated blue sapphires are found, making it uncommon relative to typical commercial goods.
-
Clarity: With minor inclusions under 10× in our own assessment, this stone is notably clean for an unheated sapphire of this size — untreated stones typically retain more visible inclusions than their heated counterparts.
-
Documentation: Independently verified by GIA, a top-tier gemological laboratory, for weight, dimensions, color, transparency, and unheated status — though it's worth noting the GIA report does not address origin. The Sri Lanka (Ceylon) origin is based on our own sourcing documentation, not a GIA origin determination.
-
Combined effect: Unheated status, deep saturated color, size, and clarity rarely converge in one stone — and when they do, that combination, not any single factor alone, is what makes a sapphire like this difficult to replace.
Buying Guidance
-
Confirm treatment on paper: Because heated stones vastly outnumber unheated ones in the market, and unheated sapphires command a real premium, always verify unheated status through an independent lab report when comparison shopping — never take a seller's word alone.
-
Understand what the origin claim rests on: This stone's Sri Lanka (Ceylon) origin reflects our own sourcing documentation. GIA's report confirms weight, dimensions, color, transparency, and unheated status, but does not include an origin determination — so the origin claim, while credible, is seller-documented rather than independently lab-confirmed.
-
Compare color consistently: View sapphires under the same lighting conditions (daylight-equivalent and incandescent) before comparing saturation and tone across listings.
-
Check the cut, not just the carat weight: This stone's mixed brilliant cut (modified brilliant crown, modified step cut pavilion) is designed to maximize brilliance in a cushion shape — a well-executed cut can make a stone face up larger and brighter than its raw measurements suggest.
-
