About this 1.5ct lab-grown round diamond

This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG526291447 or 526291447. Listed at 16 retailers as of October 30, 2026, with prices from £307 to £1,330, a £1,022 spread on the same certified stone. MOH London lists it at £1,330. 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.
