This 4.99ct 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 LG844658123 or 844658123. Listed at 19 retailers as of November 1, 2026, with prices from $1,179 to $6,446, a $5,267 spread on the same certified stone. Brilliant Earth lists it at $6,446. 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.
