About this 1.02ct natural heart diamond

This 1.02ct natural heart sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7543739184. Listed at 15 retailers as of November 5, 2026, with prices from £1,518 to £4,061, a £2,542 spread on the same certified stone. NZ Jewellers lists it at £4,061. 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.
