About this 1.7ct natural radiant diamond

This 1.7ct natural radiant sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2564413509. Listed at 14 retailers as of November 3, 2026, with prices from HK$30,746 to HK$67,809, a HK$37,063 spread on the same certified stone. NZ Jewellers lists it at HK$67,809. 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.
