About this 2.5ct lab-grown round diamond

This 2.5ct lab-grown round sits in the two to three carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436073769 or 436073769. Listed at 10 retailers as of November 5, 2026, with prices from £1,018 to £6,473, a £5,455 spread on the same certified stone. MOH London lists it at £6,473. 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.
