About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 6565404058. Listed at 21 retailers as of November 4, 2026, with prices from £3,138 to £6,865, a £3,727 spread on the same certified stone. NZ Jewellers lists it at £6,865. 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.
