This 3.55ct lab-grown heart sits in the three to five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849637381 or 849637381. Listed at 3 retailers as of October 27, 2026, with prices from £545 to £769, a £225 spread on the same certified stone. 77 Diamonds lists it at £769. 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.
