About this 1.1ct lab-grown marquise diamond

This 1.1ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG847635109 or 847635109. Listed at 12 retailers as of November 2, 2026, with prices from $311 to $1,890, a $1,579 spread on the same certified stone. Brilliant Earth lists it at $1,890. 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.
