This 1.35ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG400933068 or 400933068. Listed at 12 retailers as of November 5, 2026, with prices from £536 to £2,434, a £1,898 spread on the same certified stone. MOH London lists it at £2,434. 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.
