This 1.16ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG529267117 or 529267117. Listed at 17 retailers as of October 26, 2026, with prices from £143 to £832, a £689 spread on the same certified stone. MOH London lists it at £832. 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.
