About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 738529032. Listed at 14 retailers as of November 5, 2026, with prices from $4,649 to $9,206, a $4,556 spread on the same certified stone. NZ Jewellers lists it at $9,206. 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.
