This 1.91ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825655968 or 825655968. Listed at 20 retailers as of October 30, 2026, with prices from $508 to $4,300, a $3,792 spread on the same certified stone. Brilliant Earth lists it at $4,300. 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.
