About this 2.05ct lab-grown marquise diamond

This 2.05ct lab-grown marquise sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG812620677 or 812620677. Listed at 24 retailers as of October 28, 2026, with prices from $1,693 to $6,392, a $4,699 spread on the same certified stone. Brilliant Earth lists it at $6,392. 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.
