About this 4ct lab-grown cushion diamond

This 4ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831605978 or 831605978. Listed at 12 retailers as of October 29, 2026, with prices from $1,601 to $5,630, a $4,029 spread on the same certified stone. Brilliant Earth lists it at $5,630. 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.
