About this 4.71ct lab-grown cushion diamond

This 4.71ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG826687764 or 826687764. Listed at 5 retailers as of October 29, 2026, with prices from £1,039 to £2,644, a £1,605 spread on the same certified stone. Taylor and Hart lists it at £2,644. 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.
