This 2.91ct lab-grown heart sits in the two to three carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG845618467 or 845618467. Listed at 9 retailers as of October 25, 2026, with prices from £563 to £1,926, a £1,362 spread on the same certified stone. Rare Carat lists it at £1,926. 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.
