About this 0.71ct natural heart diamond

This 0.71ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 754531528. Listed at 13 retailers as of October 31, 2026, with prices from $1,124 to $3,590, a $2,466 spread on the same certified stone. NZ Jewellers lists it at $3,590. 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.
