About this 1.15ct lab-grown cushion diamond

This 1.15ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG739563055 or 739563055. Listed at 12 retailers as of October 30, 2026, with prices from £123 to £767, a £643 spread on the same certified stone. Reve Diamonds lists it at £767. 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.
