This 0.79ct lab-grown radiant sits in the just-under-one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG644419544 or 644419544. Listed at 3 retailers as of November 5, 2026, with prices from £359 to £438, a £79 spread on the same certified stone. Diamond Quarter lists it at £438. 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.
