About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 550249567. Listed at 14 retailers as of November 5, 2026, with prices from $2,807 to $8,203, a $5,395 spread on the same certified stone. NZ Jewellers lists it at $8,203. 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.
