About this 1ct natural round diamond

This 1ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by GIA 5403787407. Listed at 23 retailers as of October 30, 2026, with prices from £1,822 to £4,020, a £2,198 spread on the same certified stone. NZ Jewellers lists it at £4,020. 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.
