About this 0.5ct lab-grown cushion diamond

This 0.5ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840665050 or 840665050. Listed at 15 retailers as of October 26, 2026, with prices from $120 to $1,120, a $1,000 spread on the same certified stone. MOH London lists it at $1,120. 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.
