This 0.43ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG756513637 or 756513637. Listed at 8 retailers as of October 31, 2026, with prices from $587 to $1,631, a $1,044 spread on the same certified stone. Taylor and Hart lists it at $1,631. 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.
