About this 1.03ct natural heart diamond

This 1.03ct natural heart sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7533871723. Listed at 4 retailers as of November 6, 2026, with prices from $2,139 to $2,987, a $848 spread on the same certified stone. GemTrove lists it at $2,987. 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.
