About this 3.54ct lab-grown cushion diamond

This 3.54ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG602324902 or 602324902. Listed at 13 retailers as of October 31, 2026, with prices from £648 to £2,643, a £1,995 spread on the same certified stone. Michael Trio lists it at £2,643. 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.
