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 VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG836626601 or 836626601. Listed at 15 retailers as of October 27, 2026, with prices from £490 to £2,473, a £1,983 spread on the same certified stone. With Clarity lists it at £2,473. 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.
