About this 0.91ct lab-grown round diamond

This 0.91ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG457056543 or 457056543. Listed at 12 retailers as of October 26, 2026, with prices from $177 to $1,027, a $850 spread on the same certified stone. MOH London lists it at $1,027. 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.
