This 0.58ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG791649871 or 791649871. Listed at 15 retailers as of October 29, 2026, with prices from $270 to $1,334, a $1,064 spread on the same certified stone. MOH London lists it at $1,334. 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.
