2.48 carat oval-cut blue sapphire, heat-treated, measuring 8.51 × 6.91 × 5.34 mm.

Accompanied by GIA Report #2235709040, a Sapphire Report confirming weight, dimensions, color, transparency, and treatment.
Expert Opinion
Ahmed Shareek's Assessment
"This 2.48 carat Ceylon sapphire hits the size where blue sapphires start reading as substantial center stones, and its vivid royal blue face-up color is exactly the saturation collectors look for in a well-heated stone. GIA Report #2235709040 backs every attribute here, so you're not taking our word for the color, clarity, or treatment."
Rarity Analysis
Rarity in blue sapphire rarely comes down to a single factor — it's the combination of size, color saturation, clarity, and verifiable documentation that separates an exceptional stone from an ordinary one. Here's how this particular sapphire measures up:
-
Color: Vivid royal blue is the color grade most buyers actively seek in blue sapphire, distinct from the pale, washed-out blues or overly dark, blackish tones that make up much of the market's lower-grade production.
-
Size: At 2.48 carats, this stone sits above the 1-2 carat range where most natural blue sapphire on the market is concentrated, and supply thins out meaningfully with each additional carat gained.
-
Treatment: This stone is heated, which is standard practice for the overwhelming majority of blue sapphire in the trade and is fully disclosed on its GIA report. Heating isn't what makes a stone rare here — the rarity lies in the clarity and saturation the heating process was able to achieve.
-
Clarity: Graded Very Very Slightly Included and eye-clean, this stone shows no inclusions visible face-up — a clarity level that isn't a given even among heated stones of comparable size.
-
Documentation: Backed by a GIA Sapphire Report, from gemology's most widely trusted independent laboratory, confirming weight, dimensions, color, and treatment.
-
Combined effect: Size above 2 carats, vivid saturated color, eye-clean clarity, and independent GIA documentation together place this stone well ahead of typical market examples — even though heat treatment alone is not the source of that rarity.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
Match the setting to the size: At 8.51 × 6.91 × 5.34 mm, this oval will present as a substantial center stone in most ring styles, so choose a prong or bezel setting that shows off the profile rather than crowding it.
-
Heat treatment here is standard and permanent: This stone has been heated, the accepted industry-standard practice used on the vast majority of blue sapphire worldwide. The effect is permanent, and GIA documents it transparently on the report — it is not a defect, simply standard treatment disclosed in full.
-
Review the GIA report before finalizing: GIA Report #2235709040 confirms this stone's weight, dimensions, color, clarity, and treatment — cross-check these figures against the listing before you buy.
-
Plan for appraisal and insurance: A stone of this size and origin is worth having independently appraised and insured once it's set, especially if the ring will be worn daily.
-
Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.
