About this 12.03ct lab-grown cushion diamond

This 12.03ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG752512015 or 752512015. Listed at 13 retailers as of October 31, 2026, with prices from £2,739 to £9,933, a £7,194 spread on the same certified stone. Taylor and Hart lists it at £9,933. 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.
