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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 754512522. Listed at 22 retailers as of November 5, 2026, with prices from £3,026 to £6,327, a £3,300 spread on the same certified stone. NZ Jewellers lists it at £6,327. 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.
