About this 4.5ct lab-grown cushion diamond

This 4.5ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG787638008 or 787638008. Listed at 4 retailers as of October 31, 2026, with prices from £3,591 to £5,164, a £1,573 spread on the same certified stone. Zales lists it at £5,164. 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.
