About this 3ct lab-grown cushion diamond

This 3ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG567371565 or 567371565. Listed at 7 retailers as of October 31, 2026, with prices from $416 to $1,800, a $1,384 spread on the same certified stone. MOH London lists it at $1,800. 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.
