This 3.06ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG768631004 or 768631004. Listed at 16 retailers as of November 1, 2026, with prices from £1,067 to £11,953, a £10,886 spread on the same certified stone. Novita Diamonds lists it at £11,953. 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.
