About this 3.01ct lab-grown cushion diamond

This 3.01ct lab-grown cushion sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG837637665 or 837637665. Listed at 11 retailers as of October 30, 2026, with prices from £1,030 to £3,881, a £2,851 spread on the same certified stone. Taylor and Hart lists it at £3,881. 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.
