About this 1.01ct lab-grown round diamond

This 1.01ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG783646722 or 783646722. Listed at 7 retailers as of October 29, 2026, with prices from £286 to £785, a £499 spread on the same certified stone. MOH London lists it at £785. 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.
