About this 3.51ct lab-grown cushion diamond

This 3.51ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG835610793 or 835610793. Listed at 19 retailers as of October 29, 2026, with prices from $627 to $3,130, a $2,503 spread on the same certified stone. Brilliant Earth lists it at $3,130. 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.
