About this 0.71ct natural heart diamond

This 0.71ct natural heart sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555520929. Listed at 8 retailers as of November 4, 2026, with prices from £543 to £951, a £408 spread on the same certified stone. GemTrove lists it at £951. 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.
