This 1.09ct 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 LG617427666 or 617427666. Listed at 12 retailers as of November 1, 2026, with prices from £214 to £1,379, a £1,165 spread on the same certified stone. Do Amore Diamonds lists it at £1,379. 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.
