About this 1.77ct lab-grown marquise diamond

This 1.77ct lab-grown marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG762544805 or 762544805. Listed at 16 retailers as of October 31, 2026, with prices from $1,214 to $4,803, a $3,589 spread on the same certified stone. Taylor and Hart lists it at $4,803. 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.
