About this 1.5ct natural heart diamond

This 1.5ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6561603515. Listed at 13 retailers as of November 5, 2026, with prices from £3,270 to £7,800, a £4,530 spread on the same certified stone. NZ Jewellers lists it at £7,800. 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.
