This 1.5ct 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 758514173. Listed at 11 retailers as of November 3, 2026, with prices from $3,778 to $7,735, a $3,957 spread on the same certified stone. NZ Jewellers lists it at $7,735. 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.
