This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG620495325 or 620495325. Listed at 6 retailers as of October 29, 2026, with prices from $280 to $1,391, a $1,111 spread on the same certified stone. MOH London lists it at $1,391. 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.
