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 VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI 563214076. Listed at 14 retailers as of November 5, 2026, with prices from $5,079 to $12,343, a $7,264 spread on the same certified stone. NZ Jewellers lists it at $12,343. 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.
