About this 3.97ct natural radiant diamond

This 3.97ct natural radiant sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6237409653. Listed at 19 retailers as of October 28, 2026, with prices from HK$467,410 to HK$858,140, a HK$390,730 spread on the same certified stone. MOH London lists it at HK$858,140. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
