About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 451093651. Listed at 13 retailers as of November 3, 2026, with prices from $9,521 to $15,621, a $6,100 spread on the same certified stone. NZ Jewellers lists it at $15,621. 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.
