This 4.53ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818696568 or 818696568. Listed at 21 retailers as of October 31, 2026, with prices from $5,814 to $24,986, a $19,172 spread on the same certified stone. Taylor and Hart lists it at $24,986. 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.
