This 0.52ct lab-grown heart sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG847690746 or 847690746. Listed at 7 retailers as of October 26, 2026, with prices from £96 to £608, a £512 spread on the same certified stone. MOH London lists it at £608. 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.
