This 3.03ct lab-grown radiant sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG607347399 or 607347399. Listed at 7 retailers as of November 5, 2026, with prices from £555 to £1,493, a £937 spread on the same certified stone. MOH London lists it at £1,493. 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.
