About this 1.71ct natural heart diamond

This 1.71ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 704515128. Listed at 18 retailers as of October 30, 2026, with prices from £2,672 to £6,136, a £3,464 spread on the same certified stone. NZ Jewellers lists it at £6,136. 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.
