This 0.73ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831688986 or 831688986. Listed at 5 retailers as of November 4, 2026, with prices from $299 to $1,135, a $836 spread on the same certified stone. Taylor and Hart lists it at $1,135. 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.
