About this 1.46ct lab-grown marquise diamond

This 1.46ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG629471978 or 629471978. Listed at 22 retailers as of November 2, 2026, with prices from $462 to $2,580, a $2,118 spread on the same certified stone. Brilliant Earth lists it at $2,580. 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.
