About this 3.9ct natural radiant diamond

This 3.9ct natural radiant sits in the three to five carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2486308842. Listed at 7 retailers as of November 2, 2026, with prices from HK$366,068 to HK$462,652, a HK$96,584 spread on the same certified stone. 77 Diamonds lists it at HK$462,652. 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.
