About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 5533390710. Listed at 19 retailers as of November 2, 2026, with prices from £4,051 to £9,337, a £5,286 spread on the same certified stone. NZ Jewellers lists it at £9,337. 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.
