About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1535412515. Listed at 15 retailers as of November 5, 2026, with prices from $1,467 to $3,861, a $2,394 spread on the same certified stone. NZ Jewellers lists it at $3,861. 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.
