About this 0.5ct lab-grown cushion diamond

This 0.5ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG620494503 or 620494503. Listed at 5 retailers as of October 26, 2026, with prices from $314 to $851, a $537 spread on the same certified stone. MOH London lists it at $851. 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.
