This 0.67ct lab-grown radiant sits in the half to three-quarter carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG646455532 or 646455532. Listed at 2 retailers as of October 29, 2026, with prices from £349 to £415, a £66 spread on the same certified stone. Diamond Quarter lists it at £415. 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.
