About this 3.5ct natural oval diamond

This 3.5ct natural oval sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 3 retailers as of November 4, 2026, with prices from HK$410,924 to HK$473,800, a HK$62,876 spread on the same certified stone. Blue Nile lists it at HK$473,800. 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.
