This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 782657313. Listed at 8 retailers as of November 2, 2026, with prices from $3,863 to $8,949, a $5,087 spread on the same certified stone. NZ Jewellers lists it at $8,949. 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.
