About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 2467898589. Listed at 11 retailers as of November 4, 2026, with prices from £1,360 to £3,823, a £2,464 spread on the same certified stone. NZ Jewellers lists it at £3,823. 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.
