About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2476405278. Listed at 16 retailers as of November 5, 2026, with prices from $6,225 to $13,327, a $7,103 spread on the same certified stone. NZ Jewellers lists it at $13,327. 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.
