About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5456634140. Listed at 10 retailers as of November 4, 2026, with prices from HK$35,574 to HK$68,520, a HK$32,946 spread on the same certified stone. MOH London lists it at HK$68,520. 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.
