This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG848617739 or 848617739. Listed at 8 retailers as of November 1, 2026, with prices from $463 to $1,475, a $1,013 spread on the same certified stone. MOH London lists it at $1,475. 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.
