About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6432830069. Listed at 14 retailers as of November 5, 2026, with prices from £2,443 to £6,093, a £3,650 spread on the same certified stone. NZ Jewellers lists it at £6,093. 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.
