This 13.05ct lab-grown heart sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG728549861 or 728549861. Listed at 18 retailers as of October 31, 2026, with prices from £4,004 to £17,508, a £13,504 spread on the same certified stone. Taylor and Hart lists it at £17,508. 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.
