About this 0.89ct lab-grown cushion diamond

This 0.89ct lab-grown cushion sits in the just-under-one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GCAL 321371368. Listed at 2 retailers as of October 29, 2026, with prices from $328 to $916, a $588 spread on the same certified stone. MOH London lists it at $916. 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.
