1.08 ct Natural Purple Sapphire, No Indications of Heating – Octagonal Step Cut | GIA Report | Sri Lanka

A natural 1.08 ct sapphire, documented by GIA Sapphire Origin Report 2241017793. The report gives the color as Purple, the shape as Octagonal, the species as Natural Corundum, the variety as Natural Sapphire, the cutting style as Step Cut, and the geographic origin as Sri Lanka — origin as an expert opinion, with a printed disclaimer to that effect. An octagonal outline finished throughout with step faceting is what the trade calls an emerald cut; that is the trade's name, not a field of the report.

Under Additional Results the report records No Indications of Heating. That is a finding about heating, and it is worth being exact about what it does and does not say. GIA examined the stone and found no indications that it had been heated; that is the whole of the sentence. We report that entry and nothing wider. We say what the report says, in the report's own words, and stop there.

The report's Color field reads one word: Purple. That is the hue expression and nothing else — no tone grade, no intensity grade, no quality judgement of any kind. GIA puts the general position plainly on its own site: "GIA doesn't grade or provide quality analysis for sapphire or other colored stones." So the photographs on this page are the stone, and we add no adjectives to it.

What the Report States, and What We Add

Field by field, here is what the document carries and what is ours:

• Origin — Sri Lanka: The report gives the geographic origin as Sri Lanka, and prints alongside it that any statement on geographic origin is an expert opinion based on a collection of observations and analytical data. The older trade name for stones from the island is Ceylon; that name belongs to the trade, and the report does not use it.
• Shape and Cutting Style — two separate fields: The report prints the shape as Octagonal and the cutting style as Step Cut. Those are two different fields and we keep them apart. Step facets are large, flat, four-sided facets cut in tiers that run parallel to the girdle, and the octagon is a rectangle with its corners cut off. An octagonal outline finished throughout with step faceting is what the trade calls an emerald cut; that name is the trade's and ours, and it is not a field of the report.
• Species and Variety — also separate: Species reads Natural Corundum and Variety reads Natural Sapphire. Color is a third field and reads Purple. The trade's habit of writing "purple sapphire" as though it were one field fuses two; we use it to help you find the stone, and we keep the fields apart when we cite the report.
• Additional Results — No Indications of Heating: GIA examined the stone and found no indications that it had been heated. That is a finding about heating. We report that entry and nothing wider.
• What the Report Establishes: Species, variety, weight, measurements, shape, color, transparency and cutting style are findings. Geographic origin is given as an expert opinion, not a finding. The Additional Results entry reads No Indications of Heating.
• Clarity — our assessment, not a grade: We find minor inclusions under 10×. That is our own observation at the loupe. GIA's colored-stone reports carry no clarity grade, so this appears on no document and should be checked against the stone.

Buying Guidance

A few practical points to consider before purchasing this stone:

• Verify the report: The physical document is headed "Sapphire Origin Report" above the report number — that is the line to check this page against the paper. Confirm that the weight (1.08 ct) and the measurements (6.81 x 4.96 x 3.38 mm) match, and run 2241017793 through GIA's online Report Check before you buy.
• Price per carat: At $1,320.00 for 1.08 ct, this works out to $1,222.22 per carat. That figure is our arithmetic on our own price, not a field of the report. Compare price per carat, not just total price, when evaluating alternatives — and compare documents too, since what one seller's paper covers is not what another's does.
• Ask what the document covers: This report's Additional Results entry reads No Indications of Heating, which is a finding about heating on a dated examination, and its Geographic Origin field carries an expert opinion rather than a finding. Ask any seller, for any stone, exactly what their document does and does not cover.
• Setting considerations: At 6.81 x 4.96 x 3.38 mm this is a rectangular stone with cut corners, and the girdle is the thin part of any faceted stone. A bezel, or prongs seated to cover the cut corners, is worth discussing with your setter for everyday wear — that is our recommendation, not a line from the report.
• Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.

Why Choose this 1.08 ct Octagonal Step-Cut Purple Sapphire?

This stone has an octagonal outline — a rectangle with its corners cut off — finished throughout with step faceting: large, flat, four-sided facets arranged in tiers that run parallel to the girdle. Facets of that kind return light in broad planes. Whether you prefer that to another faceting style is a matter of taste; neither is a grade, and the report grades neither. The stone measures 6.81 x 4.96 mm across the girdle at a total depth of 3.38 mm.

Key Benefits of this Natural Purple Sapphire

• Additional Results: No Indications of Heating
  GIA examined the stone and found no indications that it had been heated. A finding about heating; we report that entry and nothing wider.
• Origin: Sri Lanka
  Given on the report as an expert opinion, with GIA's printed disclaimer alongside it.
• Shape and Cutting Style, in Two Fields
  Shape reads Octagonal and Cutting Style reads Step Cut. The trade's name for that pairing is an emerald cut; it is not a field of the report.
• Color: Purple
  The report's Color field, one word. It carries no tone grade and no intensity grade.
• GIA-Documented
  Species, variety, weight, measurements, shape, color, transparency and cutting style as findings; geographic origin as an expert opinion.
• Mohs Hardness 9
  Very high scratch resistance, which is not the same as toughness. For comparison, GIA publishes 9.25 for synthetic moissanite. The report's Excellent toughness entry is GIA's figure for corundum as a species.

What you are buying is a single unmounted stone and the document that goes with it. The report says what it says, we have marked what is ours, and the rest is a matter of looking at the stone.

Care

Clean this sapphire with lukewarm water, mild soap, and a soft brush. Store it separately from other jewelry to prevent scratching, and remove it before heavy activity or manual work. GIA publishes its own sapphire care guidance and attaches its own conditions to ultrasonic and steam cleaning; we prefer not to use either on a stone we did not set ourselves, because we cannot see how it is held. That is our preference, not a warning from the report.
