About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG675577345 or 675577345. Listed at 13 retailers as of October 28, 2026, with prices from $487 to $2,399, a $1,912 spread on the same certified stone. MOH London lists it at $2,399. 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.
