0.43 ct Natural Unheated Yellow Sapphire – Round Cut | AGCL Certified | Sri Lanka (Ceylon)

A natural 0.43 carat round yellow sapphire, completely unheated, documented on AGCL Report #M262740. At 0.43 carats in a round cut, this is a small stone with the most practical format for its scale — round calibrated sapphires fit the widest range of standard earring, pendant, and accent settings without custom fabrication. Natural and unheated, the yellow color is exactly as the earth formed it, which is a meaningful distinction even at sub-half-carat weight.

Good to Know

A few practical points to weigh before purchasing this specific stone:

• View it under natural daylight. Yellow sapphire's saturation can appear warmer under incandescent light and cooler under daylight or LED — check both before deciding.
• Confirm your setting's seat size against 4.60 mm. This round calibrates close to a standard 4.5–4.75mm seat — verify your specific mounting before ordering.
• Request the lab report directly, not a summary. AGCL Report #M262740 documents this stone's treatment status independently — ask for it when comparison-shopping.
• If buying for Jyotish use, confirm unheated status explicitly. Traditional use of Pukhraj typically requires unheated natural sapphire; this stone's AGCL report supports that requirement.
• Ask for a personal video if you would like to see the stone in motion before finalizing the purchase.
