About this 3.59ct lab-grown cushion diamond

This 3.59ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG724596771 or 724596771. Listed at 13 retailers as of October 30, 2026, with prices from $725 to $3,480, a $2,755 spread on the same certified stone. Brilliant Earth lists it at $3,480. 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.
