About this 1.24ct lab-grown cushion diamond

This 1.24ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG848646701 or 848646701. Listed at 11 retailers as of November 4, 2026, with prices from £158 to £865, a £707 spread on the same certified stone. Reve Diamonds lists it at £865. 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.
