About this 1.72ct natural radiant diamond

This 1.72ct natural radiant sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2155360245. Listed at 17 retailers as of November 5, 2026, with prices from £5,126 to £11,040, a £5,914 spread on the same certified stone. NZ Jewellers lists it at £11,040. 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.
