About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551332569. Listed at 21 retailers as of October 27, 2026, with prices from HK$43,803 to HK$97,029, a HK$53,225 spread on the same certified stone. NZ Jewellers lists it at HK$97,029. 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.
