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 Rectangular Cushion Violet Sapphire, unheated and documented on AGCL Report #M2511400. Sourced from Sri Lanka (Ceylon), this stone's cushion geometry concentrates its violet hue across the face, producing deeper saturation than oval or round equivalents of the same weight. Violet sapphire occupies the cooler, bluer end of the purple corundum range. Unheated violet sapphires from Ceylon are among the rarer stones in the catalog — heat treatment tends to shift violet toward blue or red, so the finest violets are almost always natural as cut.
Expert Opinion
Ahmed Shareek's Assessment
"Violet sapphire gets confused with purple more often than any other sapphire color, but it's a genuinely distinct hue that sits closer to blue on the color range. Because heat treatment usually pushes violet material toward a more marketable blue or purple, an unheated stone like this 1.29 ct Ceylon violet is a real find — the color you see is what the earth made, not what a furnace produced."
Rarity Analysis
Violet sapphire is a minority color within overall sapphire production, and unheated material makes up a smaller share of that already limited supply.
-
Color: Violet sapphire is a minority color, often confused with purple but formally distinct — it sits closer to blue on the corundum color range.
-
Size: At 1.29 carats, this stone is a workable center-stone weight, sized for a ring or pendant rather than an accent piece.
-
Treatment: Most violet sapphire on the market is heat-treated, often to push the color toward a more commercially familiar blue or purple. Unheated is a meaningfully smaller subset of overall violet sapphire supply.
-
Clarity: Graded Slightly Included — noted honestly rather than upgraded.
-
Documentation: Documented on AGCL Report #M2511400, addressing weight, dimensions, color, and treatment. The Sri Lanka (Ceylon) origin is presented as the store's own assessment rather than a lab-confirmed determination, as AGCL reports of this type do not address geographic origin.
-
Combined effect: An unheated violet sapphire at a usable carat weight is a less common combination than any single factor suggests on its own — most violet material on the market is either heat-treated, a different color entirely, or sold loosely as "purple" without the distinction being made.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
View it in different lighting: Violet sapphire's color can shift depending on the light source — warm incandescent lighting can pull it toward a more purple cast, while daylight or fluorescent light brings out the cooler, bluer violet. Ask to see the stone (or photos/video) under more than one lighting environment before deciding.
-
Confirm the setting fits the stone: At 6.53 × 5.27 mm, this rectangular cushion 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 violet sapphire on the market is heat-treated, confirm unheated status through an independent lab report, and check whether that report addresses geographic origin — as with this stone, not every report does.
-
Weigh availability against the Rarity Analysis above: Unheated violet sapphire in this size and clarity is less routinely available than treated stones, purple-labeled material, or smaller sizes, which is worth factoring into any price comparison.

One of a Kind
This is a single natural gemstone, not a lab-created or manufactured stone — no two are exactly alike. Once sold, this particular 1.29 ct violet sapphire will not be available again.
Care
Clean with warm soapy water and a soft brush. Avoid ultrasonic cleaners and harsh chemicals, and store separately from harder or abrasive materials to prevent scratching.
This 1.29 ct Rectangular Cushion Violet Sapphire has been hand-selected for color balance and cutting quality — the violet-blue balance that defines the variety requires careful sourcing at origin. Documented on AGCL Report #M2511400, it is unheated and natural, with a hue that sits in genuine rarity territory: most violet sapphires on the market have been heated, and heat treatment often disrupts the delicate violet-blue balance that makes this color desirable.
Perfect Uses
- Non-traditional engagement ring center stone
- Custom fine jewelry pendant
- Collectors of unheated Ceylon sapphires
- Three-stone ring alongside diamonds or white sapphires
- Anniversary or meaningful milestone gift
