This 4.78ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG847661603 or 847661603. Listed at 16 retailers as of October 27, 2026, with prices from $880 to $6,215, a $5,335 spread on the same certified stone. Brilliant Earth lists it at $6,215. 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.
