About this 0.72ct natural heart diamond

This 0.72ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2557156015. Listed at 4 retailers as of November 6, 2026, with prices from £420 to £786, a £366 spread on the same certified stone. GemTrove lists it at £786. 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.
