Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.46 ct oval-cut purple sapphire, unheated, measuring 7.42 × 6.58 × 4.05 mm. The oval shape spreads the stone's purple hue across a broad face-up surface, giving strong visual presence at this weight. Purple sapphire sits between red and blue in natural corundum, and heat treatment typically shifts it toward pink or blue — unheated purple at this size is a genuine find. Origin is presented as the store's own assessment of Sri Lanka (Ceylon), as the AGCL report does not address geographic origin. Accompanied by AGCL Report #M2511401, confirming weight, dimensions, color, and treatment.
Expert Opinion
Ahmed Shareek's Assessment
"Purple sapphire is one of the color ranges most likely to be heat-treated toward pink or blue, so an unheated 1.46 ct stone like this one — clean, well-cut, and honestly documented — is harder to come by than its size alone suggests."
Rarity Analysis
Purple sapphire is a minority color within overall sapphire production, and unheated examples make up a smaller share still.
-
Color: Purple sapphire sits between red and blue on the corundum color range and is seen far less often than blue, pink, or yellow sapphire in typical market supply.
-
Size: At 1.46 carats, this stone is a solid, wearable center-stone weight — above the smaller accent range while still being an attainable size for a purple sapphire.
-
Treatment: Most purple sapphire on the market is heat-treated, often specifically to push the color toward the more commercially familiar pink or blue. A stone that has kept its natural, unheated purple color is a meaningfully smaller subset.
-
Clarity: Graded Loupe Clean — eye-clean and clean even under magnification, a favorable grade that isn't a given at this color and size.
-
Documentation: Backed by AGCL Report #M2511401, confirming weight, dimensions, color, and treatment. The report does not address geographic origin, so the Sri Lanka (Ceylon) origin stated here is the store's own assessment rather than a lab-confirmed determination.
-
Combined effect: An unheated purple sapphire with loupe-clean clarity at a usable carat weight is a less common combination than any one of those factors would suggest on its own — most purple sapphire on the market is either heat-treated, smaller, or more included.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
View it in different lighting: Purple sapphire's color can shift depending on light source — warm indoor lighting can push it toward a redder cast, while daylight or fluorescent light brings out a cooler, bluer purple. Ask to see the stone (or photos/video) in more than one lighting environment.
-
Confirm the setting fits the stone: At 7.42 × 6.58 mm, this oval will need a mounting sized to that footprint — check a prospective setting's stated stone dimensions before ordering, especially for a custom build.
-
Verify treatment through documentation, not a seller's claim alone: Since most purple sapphire on the market is heat-treated, confirm unheated status through an independent lab report, and check whether that report addresses geographic origin or not — as here, not every report does.
-
Weigh availability against the Rarity Analysis above: Unheated purple sapphire in this size and clarity is less routinely available than treated stones or smaller sizes, which is worth factoring into any price comparison against undocumented or unheated-unverified listings.
