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 21 retailers as of October 27, 2026, with prices from $313 to $2,387, a $2,073 spread on the same certified stone. Queensmith lists it at $2,387. 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.
