About this 0.9ct lab-grown round diamond

This 0.9ct lab-grown round sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG805672635 or 805672635. Listed at 17 retailers as of October 26, 2026, with prices from £106 to £991, a £885 spread on the same certified stone. MOH London lists it at £991. 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.
