About this 1.52ct lab-grown cushion diamond

This 1.52ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG530227478 or 530227478. Listed at 10 retailers as of October 25, 2026, with prices from $305 to $2,360, a $2,055 spread on the same certified stone. Do Amore Diamonds lists it at $2,360. 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.
