About this 1.64ct lab-grown cushion diamond

This 1.64ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG607349476 or 607349476. Listed at 6 retailers as of October 28, 2026, with prices from $337 to $2,705, a $2,367 spread on the same certified stone. Do Amore Diamonds lists it at $2,705. 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.
