This 1.87ct 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), with a very-good cut grade and certified by IGI LG825634211 or 825634211. Listed at 16 retailers as of October 30, 2026, with prices from $813 to $4,935, a $4,122 spread on the same certified stone. Brilliant Earth lists it at $4,935. 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.
