This 3.01ct lab-grown round sits in the three to five carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG478118406 or 478118406. Listed at 18 retailers as of November 3, 2026, with prices from £319 to £1,454, a £1,135 spread on the same certified stone. MOH London lists it at £1,454. 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.
