This 1.51ct natural heart 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 and certified by IGI 737520470. Listed at 12 retailers as of November 5, 2026, with prices from $4,714 to $9,651, a $4,937 spread on the same certified stone. NZ Jewellers lists it at $9,651. 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.
