This 5.07ct lab-grown marquise sits in the over five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG835668802 or 835668802. Listed at 18 retailers as of October 27, 2026, with prices from $6,465 to $25,874, a $19,409 spread on the same certified stone. Taylor and Hart lists it at $25,874. 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.
