About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6505181551. Listed at 13 retailers as of October 26, 2026, with prices from HK$18,648 to HK$40,717, a HK$22,069 spread on the same certified stone. MOH London lists it at HK$40,717. 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.
