About this 1.04ct lab-grown marquise diamond

This 1.04ct 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 LG640417534 or 640417534. Listed at 22 retailers as of October 27, 2026, with prices from $310 to $2,750, a $2,440 spread on the same certified stone. Do Amore Diamonds lists it at $2,750. 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.
