About this 12.39ct natural oval diamond

This 12.39ct natural oval sits in the over five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5242038662. Listed at 5 retailers as of October 28, 2026, with prices from HK$7,353,057 to HK$9,734,286, a HK$2,381,229 spread on the same certified stone. Ritani lists it at HK$9,734,286. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
