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 LG400934998 or 400934998. Listed at 3 retailers as of November 1, 2026, with prices from $585 to $1,189, a $604 spread on the same certified stone. Rare Carat lists it at $1,189. 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.
