This 12.01ct lab-grown round sits in the over five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG798617023 or 798617023. Listed at 16 retailers as of October 29, 2026, with prices from £1,644 to £6,666, a £5,022 spread on the same certified stone. Taylor and Hart lists it at £6,666. 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.
