This 1.5ct natural round sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by GIA 3455211737. Listed at 13 retailers as of November 5, 2026, with prices from £1,322 to £3,637, a £2,315 spread on the same certified stone. NZ Jewellers lists it at £3,637. 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.
