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 4, 2026, with prices from £7,074 to £11,606, a £4,532 spread on the same certified stone. NZ Jewellers lists it at £11,606. 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.
