This 3.07ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830674947 or 830674947. Listed at 16 retailers as of October 31, 2026, with prices from $2,549 to $10,313, a $7,764 spread on the same certified stone. Taylor and Hart lists it at $10,313. 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.
