This 1.88ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG768630864 or 768630864. Listed at 13 retailers as of October 30, 2026, with prices from $721 to $5,308, a $4,587 spread on the same certified stone. Brilliant Earth lists it at $5,308. 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.
