About this 1.7ct natural radiant diamond

This 1.7ct natural radiant sits in the one-and-a-half to two 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 5516434829. Listed at 20 retailers as of October 28, 2026, with prices from HK$57,590 to HK$129,202, a HK$71,611 spread on the same certified stone. NZ Jewellers lists it at HK$129,202. 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.
