About this 14.49ct lab-grown cushion diamond

This 14.49ct lab-grown cushion sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG605356478 or 605356478. Listed at 14 retailers as of October 30, 2026, with prices from £5,541 to £20,126, a £14,586 spread on the same certified stone. Taylor and Hart lists it at £20,126. 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.
