About this 1.81ct natural radiant diamond

This 1.81ct 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 6555000813. Listed at 20 retailers as of November 5, 2026, with prices from $6,501 to $14,815, a $8,313 spread on the same certified stone. NZ Jewellers lists it at $14,815. 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.
