This 0.99ct lab-grown radiant sits in the just-under-one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG520213917 or 520213917. Listed at 13 retailers as of November 5, 2026, with prices from £261 to £1,156, a £895 spread on the same certified stone. MOH London lists it at £1,156. 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.
