About this 4.1ct lab-grown heart diamond

This 4.1ct lab-grown heart sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG750587152 or 750587152. Listed at 15 retailers as of November 6, 2026, with prices from £437 to £2,413, a £1,976 spread on the same certified stone. Brilliant Earth lists it at £2,413. 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.
