About this 1.3ct natural radiant diamond

This 1.3ct natural radiant sits in the one-and-a-quarter to one-and-a-half 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 2557892650. Listed at 7 retailers as of October 30, 2026, with prices from HK$25,307 to HK$62,138, a HK$36,831 spread on the same certified stone. Diamond Wish lists it at HK$62,138. 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.
