2.175 ct Natural Unheated Yellow Sapphire – Cushion Cut | GIA Certified | Sri Lanka (Ceylon)

2.175 carat rectangular cushion-cut yellow sapphire, sourced from Sri Lanka (Ceylon) and completely unheated, measuring 8.20 × 6.02 × 4.50 mm. At over 2 carats unheated, this is a meaningful size in a color where unheated Ceylon material above 1.5 carats becomes genuinely uncommon. Accompanied by GIA Report #1236922088, a Sapphire Report confirming weight, dimensions, color, transparency, and treatment.

Rarity Analysis

• Treatment: The overwhelming majority of yellow sapphire in the market is heat-treated to produce or improve its color; this stone shows no indications of heating, per GIA.
• Size: Unheated Ceylon yellow sapphire above 1.5–2 carats is genuinely uncommon — most natural-color material of this hue is found in smaller sizes.
• Color: A clean Golden Yellow (Lemon Yellow) hue, without the need for treatment to reach this saturation.
• Clarity: Eye-clean, with no visible inclusions to the unaided eye — our own assessment, not a GIA grade.
• Documentation: Accompanied by GIA Report #1236922088, confirming weight, dimensions, color, transparency, and treatment. Origin is seller-stated as Sri Lanka (Ceylon); this GIA report is a standard Sapphire Report, not an Origin Report, so GIA has not confirmed origin.
• Combined effect: An unheated, eye-clean, GIA-documented yellow sapphire above 2 carats is a scarce combination of factors that rarely lines up in one stone.

Buying Guidance

• Always confirm unheated status through an independent lab report rather than a seller's word alone — this stone's GIA report explicitly states no indications of heating.
• Understand what the report does and does not cover: this GIA Sapphire Report confirms weight, dimensions, color, transparency, and treatment, but does not confirm origin.
• Treat the Sri Lanka (Ceylon) origin as seller-stated rather than lab-confirmed, since no Origin Report accompanies this stone.
• Compare pricing against heated yellow sapphires of similar size and color — unheated material of this size and clarity commands a real premium for good reason.
• Try Before You Buy: Request additional photos or a video call to view the stone in hand before purchasing.
