About this 1.51ct natural radiant diamond

This 1.51ct 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 6485980459. Listed at 23 retailers as of November 4, 2026, with prices from HK$19,460 to HK$44,203, a HK$24,743 spread on the same certified stone. NZ Jewellers lists it at HK$44,203. 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.
