About this 2.5ct lab-grown oval diamond

This 2.5ct lab-grown oval sits in the two to three carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG776620127 or 776620127. Listed at 14 retailers as of November 1, 2026, with prices from £232 to £1,155, a £922 spread on the same certified stone. MOH London lists it at £1,155. 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.
