About this 2.97ct lab-grown cushion diamond

This 2.97ct lab-grown cushion sits in the two to three carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG823681223 or 823681223. Listed at 3 retailers as of November 4, 2026, with prices from £348 to £1,273, a £925 spread on the same certified stone. Brilliance lists it at £1,273. 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.
