About this 1.18ct lab-grown round diamond

This 1.18ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG763668413 or 763668413. Listed at 15 retailers as of October 26, 2026, with prices from £115 to £666, a £551 spread on the same certified stone. MOH London lists it at £666. 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.
