This 3.01ct lab-grown round sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG546221589 or 546221589. Listed at 12 retailers as of November 5, 2026, with prices from £511 to £2,321, a £1,810 spread on the same certified stone. MOH London lists it at £2,321. 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.
