This 0.79ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818657664 or 818657664. Listed at 19 retailers as of November 3, 2026, with prices from £259 to £1,152, a £893 spread on the same certified stone. Reve Diamonds lists it at £1,152. 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.
