This 0.71ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG687547271 or 687547271. Listed at 19 retailers as of November 4, 2026, with prices from £140 to £858, a £718 spread on the same certified stone. Reve Diamonds lists it at £858. 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.
