About this 3.51ct natural oval diamond

This 3.51ct natural oval sits in the three to five carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1568271548. Listed at 16 retailers as of November 1, 2026, with prices from HK$459,229 to HK$740,195, a HK$280,966 spread on the same certified stone. Helzberg Diamonds lists it at HK$740,195. 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.
