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 LG801684843 or 801684843. Listed at 22 retailers as of November 4, 2026, with prices from $281 to $2,160, a $1,879 spread on the same certified stone. Brilliant Earth lists it at $2,160. 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.
