About this 1ct lab-grown marquise diamond

This 1ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG843685848 or 843685848. Listed at 17 retailers as of October 30, 2026, with prices from $369 to $2,235, a $1,866 spread on the same certified stone. Brilliant Earth lists it at $2,235. 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.
