About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG846647468 or 846647468. Listed at 8 retailers as of October 26, 2026, with prices from £173 to £626, a £452 spread on the same certified stone. MOH London lists it at £626. 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.
