About this 1.67ct lab-grown cushion diamond

This 1.67ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG538297406 or 538297406. Listed at 14 retailers as of October 29, 2026, with prices from $318 to $2,095, a $1,777 spread on the same certified stone. Brilliant Earth lists it at $2,095. 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.
