About this 2.05ct lab-grown cushion diamond

This 2.05ct lab-grown cushion sits in the two to three carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG831677216 or 831677216. Listed at 18 retailers as of October 28, 2026, with prices from £307 to £2,008, a £1,700 spread on the same certified stone. Brilliant Earth lists it at £2,008. 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.
