About this 3.05ct lab-grown marquise diamond

This 3.05ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844607814 or 844607814. Listed at 5 retailers as of October 30, 2026, with prices from $2,732 to $8,130, a $5,398 spread on the same certified stone. Taylor and Hart lists it at $8,130. 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.
