About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 6401966755. Listed at 13 retailers as of October 30, 2026, with prices from £2,856 to £6,482, a £3,626 spread on the same certified stone. NZ Jewellers lists it at £6,482. 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.
