About this 4.09ct lab-grown cushion diamond

This 4.09ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG642485936 or 642485936. Listed at 12 retailers as of October 31, 2026, with prices from $725 to $3,520, a $2,795 spread on the same certified stone. Brilliant Earth lists it at $3,520. 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.
