About this 1ct lab-grown princess diamond

This 1ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG706531173 or 706531173. Listed at 8 retailers as of November 4, 2026, with prices from £214 to £593, a £379 spread on the same certified stone. MOH London lists it at £593. 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.
