This 0.52ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG750556582 or 750556582. Listed at 5 retailers as of October 29, 2026, with prices from $499 to $2,467, a $1,968 spread on the same certified stone. MOH London lists it at $2,467. 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.
