About this 1.01ct natural round diamond

This 1.01ct natural round sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 2436819799. Listed at 22 retailers as of October 31, 2026, with prices from £1,522 to £4,393, a £2,872 spread on the same certified stone. NZ Jewellers lists it at £4,393. 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.
