About this 4.05ct lab-grown cushion diamond

This 4.05ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG843651164 or 843651164. Listed at 16 retailers as of October 31, 2026, with prices from $604 to $5,070, a $4,466 spread on the same certified stone. Brilliant Earth lists it at $5,070. 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.
