This 1.25ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG529259381 or 529259381. Listed at 7 retailers as of November 2, 2026, with prices from £277 to £834, a £556 spread on the same certified stone. MOH London lists it at £834. 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.
