About this 1.7ct natural radiant diamond

This 1.7ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6415685458. Listed at 6 retailers as of October 29, 2026, with prices from HK$30,284 to HK$59,455, a HK$29,171 spread on the same certified stone. MOH London lists it at HK$59,455. 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.
