This 3.03ct lab-grown radiant sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG818682523 or 818682523. Listed at 20 retailers as of October 30, 2026, with prices from £318 to £1,590, a £1,272 spread on the same certified stone. Rare Carat lists it at £1,590. 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.
