About this 1.62ct lab-grown oval diamond

This 1.62ct lab-grown oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG778687913 or 778687913. Listed at 5 retailers as of November 1, 2026, with prices from £281 to £1,077, a £795 spread on the same certified stone. Frank Darling lists it at £1,077. 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.
