2.008 carat radiant-cut blue sapphire, sourced from Sri Lanka (Ceylon) and completely unheated, measuring 7.91 × 5.48 × 4.74 mm. The radiant cut combines a step-cut style outline with brilliant faceting, producing both structural elegance and strong light return — an unusual and striking choice at this size. Accompanied by GIA Report #5232922099, a Sapphire Report confirming weight, dimensions, color, transparency, and treatment (geographic origin was not requested for this report).
Expert Opinion
Ahmed Shareek's Assessment
"What stands out here is the combination: a radiant cut is a bold, uncommon choice for sapphire, and pairing it with fully unheated color above two carats is a real rarity in this market. Most stones this size have been heat-treated to reach this kind of saturation — this one didn't need it."
Rarity Analysis
-
Unheated above 2 carats: The overwhelming majority of commercial-grade blue sapphire on the market is heat-treated to improve color and clarity. A stone at 2.008 carats confirmed unheated by GIA is a meaningfully scarcer category, and the price premium for unheated goods widens sharply above the 2-carat mark.
-
Radiant cut on sapphire: Fine sapphire is most often cut as oval, cushion, or round to maximize yield and color face-up. A radiant — with its hybrid step-cut outline and brilliant faceting — is an uncommon choice for this material, making this a distinctive stone for anyone seeking something outside the standard shapes.
-
Color saturation: The stone displays a rich Royal Blue, the saturation level most associated with fine Ceylon sapphire, achieved here without any heat treatment.
-
Clarity: Minor inclusions under 10× in our own assessment, indicating a clean, eye-clean-to-the-loupe stone with minimal interference to brilliance.
-
Independent documentation: Backed by GIA Report #5232922099, confirming weight, dimensions, color, transparency, and treatment. Note that geographic origin was not requested as part of this report, so the Sri Lanka (Ceylon) origin stated here is seller-stated based on sourcing, not a GIA-confirmed origin determination.
-
Combined effect: An unheated sapphire of this size is uncommon on its own; pairing that with a radiant cut rarely seen in this gem material makes this a distinctive stone for a collector or buyer seeking something outside the standard oval/cushion/round norm.
Buying Guidance
- When comparison shopping, always confirm unheated status through an independent lab report (such as GIA) rather than a seller's claim alone — treatment disclosure materially affects value, and this distinction should always be documented, not assumed.
- Look closely at light return: this stone's radiant cut combines a step-cut outline with brilliant faceting, which tends to produce a lively, sparkling face-up appearance rather than the broader color blocks typical of a pure step cut — compare this against other radiants for consistent scintillation across the table.
- Remember that this GIA report did not include an origin opinion, so the Sri Lanka (Ceylon) attribution is seller-stated based on sourcing rather than a GIA-determined origin — factor that distinction into any origin-based price comparison.
- Evaluate clarity under magnification as well as with the naked eye; a stone with minor inclusions under 10× — our own assessment, not a GIA grade — should still read clean face-up.
-
Try Before You Buy: Request additional photos or a video call to see the stone's color and brilliance in person before purchasing, especially given the unusual cut and unheated color you're paying a premium for.
