About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6545253009. Listed at 4 retailers as of November 4, 2026, with prices from £3,041 to £4,352, a £1,311 spread on the same certified stone. GemTrove lists it at £4,352. 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.
