This 14.48ct lab-grown radiant sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605385663 or 605385663. Listed at 19 retailers as of October 30, 2026, with prices from £1,603 to £10,687, a £9,084 spread on the same certified stone. Brilliant Earth lists it at £10,687. 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.
