This 2.03ct lab-grown heart sits in the two to three carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG846656714 or 846656714. Listed at 7 retailers as of November 6, 2026, with prices from £277 to £1,113, a £836 spread on the same certified stone. Brilliant Earth lists it at £1,113. 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.
