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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 2245070904. Listed at 22 retailers as of November 4, 2026, with prices from £3,702 to £7,203, a £3,502 spread on the same certified stone. NZ Jewellers lists it at £7,203. 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.
