This 1.46ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839643663 or 839643663. Listed at 6 retailers as of October 26, 2026, with prices from £305 to £768, a £463 spread on the same certified stone. MOH London lists it at £768. 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.
