This 3.57ct 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 LG655425515 or 655425515. Listed at 6 retailers as of October 29, 2026, with prices from $1,320 to $8,186, a $6,866 spread on the same certified stone. Do Amore Diamonds lists it at $8,186. 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.
