About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 6551841061. Listed at 18 retailers as of November 4, 2026, with prices from £2,539 to £5,780, a £3,241 spread on the same certified stone. NZ Jewellers lists it at £5,780. 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.
