About this 12.05ct lab-grown cushion diamond

This 12.05ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG732544208 or 732544208. Listed at 15 retailers as of October 31, 2026, with prices from £1,653 to £7,455, a £5,802 spread on the same certified stone. Taylor and Hart lists it at £7,455. 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.
