This 1ct lab-grown marquise sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG828681336 or 828681336. Listed at 22 retailers as of October 30, 2026, with prices from $237 to $1,740, a $1,503 spread on the same certified stone. Brilliant Earth lists it at $1,740. 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.
