About this 1.01ct lab-grown cushion diamond

This 1.01ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG836689243 or 836689243. Listed at 15 retailers as of October 27, 2026, with prices from £134 to £1,069, a £935 spread on the same certified stone. Queensmith lists it at £1,069. 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.
