This 1.6ct lab-grown radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG615366621 or 615366621. Listed at 20 retailers as of October 31, 2026, with prices from £155 to £1,455, a £1,300 spread on the same certified stone. Brilliant Earth lists it at £1,455. 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.
