About this 1.19ct lab-grown round diamond

This 1.19ct lab-grown round sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG710541001 or 710541001. Listed at 12 retailers as of November 1, 2026, with prices from £111 to £641, a £531 spread on the same certified stone. MOH London lists it at £641. 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.
