This 1.45ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG575388707 or 575388707. Listed at 6 retailers as of October 26, 2026, with prices from £300 to £795, a £495 spread on the same certified stone. MOH London lists it at £795. 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.
