This 1.23ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG611361110 or 611361110. Listed at 10 retailers as of November 4, 2026, with prices from £156 to £1,341, a £1,184 spread on the same certified stone. Do Amore Diamonds lists it at £1,341. 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.
