About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2221152020. Listed at 20 retailers as of October 28, 2026, with prices from £3,324 to £7,112, a £3,788 spread on the same certified stone. NZ Jewellers lists it at £7,112. 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.
