This 3.71ct lab-grown heart sits in the three to five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG843603126 or 843603126. Listed at 16 retailers as of October 28, 2026, with prices from £440 to £6,105, a £5,665 spread on the same certified stone. Brilliant Earth lists it at £6,105. 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.
