About this 1.29ct lab-grown oval diamond

This 1.29ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG778614654 or 778614654. Listed at 20 retailers as of November 3, 2026, with prices from £156 to £775, a £619 spread on the same certified stone. MOH London lists it at £775. 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.
