About this 0.56ct natural heart diamond

This 0.56ct natural heart sits in the half to three-quarter carat band, graded G 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 2556102617. Listed at 2 retailers as of November 6, 2026, with prices from £326 to £404, a £78 spread on the same certified stone. 77 Diamonds lists it at £404. 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.
