About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 707521247. Listed at 14 retailers as of November 5, 2026, with prices from £299 to £1,340, a £1,041 spread on the same certified stone. NZ Jewellers lists it at £1,340. 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.
