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 VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG601389228 or 601389228. Listed at 23 retailers as of November 2, 2026, with prices from £113 to £1,046, a £933 spread on the same certified stone. MOH London lists it at £1,046. 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.
