This 3.04ct 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 LG843654638 or 843654638. Listed at 17 retailers as of November 3, 2026, with prices from $4,311 to $15,573, a $11,261 spread on the same certified stone. Taylor and Hart lists it at $15,573. 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.
