3.13 ct Natural Unheated Yellow Sapphire – Round Cut | GIA Certified | Sri Lanka (Ceylon)

3.13 carat round-cut yellow sapphire, unheated, measuring 8.20–8.33 × 6.25 mm, from Sri Lanka (Ceylon). Yellow sapphire at 3+ carats in unheated quality is a meaningful find — most unheated Ceylon yellows in the commercial market are sub-1-carat. Accompanied by GIA Report #2235835331, a Sapphire Origin Report confirming weight, dimensions, color, transparency, treatment (no indications of heating), and geographic origin (Sri Lanka).

Rarity Analysis

• Color: A clean, saturated lemon yellow, free of the brownish or greenish undertones that lower-grade yellow sapphire often shows.
• Size vs. unheated supply: Most unheated yellow sapphire reaching the commercial market is under 1 carat; at 3.13 carats, this stone sits well outside that typical supply band.
• Treatment: Confirmed unheated (no indications of heating). The large majority of yellow sapphire sold today is heat-treated to produce or improve its color, which makes an untreated stone of this size a genuine outlier.
• Clarity: Eye-clean — no inclusions visible without magnification — adding to the stone's face-up appeal without any need for treatment to mask flaws — our own assessment, not a GIA grade.
• Documentation: Backed by a GIA Sapphire Origin Report, a dual-confirmation document that independently verifies both treatment status and geographic origin (Sri Lanka/Ceylon) — a level of documentation most commercial yellow sapphire never receives.
• Combined effect: Natural lemon-yellow color, unheated status, above-average size for untreated material, eye-clean clarity, and dual-confirmed GIA documentation together make this a stone that is genuinely difficult to replace in today's market.

Buying Guidance

• Verify treatment on paper: Most yellow sapphire on the market is heated, so when comparison shopping, confirm treatment status on an independent lab report rather than a seller's description alone — this stone's GIA report states "no indications of heating."
• Confirm the origin claim independently: Not every "Ceylon" sapphire sold online has lab-confirmed origin; this stone's Sri Lankan origin is verified by GIA, not simply asserted by the seller.
• Weigh cut quality alongside carat weight: A yellow sapphire's face-up brightness depends heavily on cut proportions — a well-executed round brilliant, as with this stone, maximizes light return, while a poorly proportioned stone can look dull even at a larger size.
• Compare pricing against similarly documented stones: heated yellow sapphire trades at a fraction of the price of unheated material of comparable size and color, so price comparisons are only meaningful against stones with matching treatment and certification.
• Try Before You Buy: Whenever possible, view the stone in hand or take advantage of a return window so you can judge color and brilliance for yourself before committing.

One of a Kind

This is a single natural gemstone, not a manufactured or lab-created replica — no two sapphires form with identical color, inclusions, and internal character. Once this stone sells, it's gone; there is no duplicate. What you see documented on the GIA report is the exact, individual stone you receive.
