About this 1.09ct lab-grown oval diamond

This 1.09ct lab-grown oval sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade. Listed at 4 retailers as of October 26, 2026, with prices from £107 to £426, a £319 spread on the same certified stone. NZ Jewellers lists it at £426. 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.
