About this 5.05ct lab-grown marquise diamond

This 5.05ct lab-grown marquise sits in the over five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG650491267 or 650491267. Listed at 17 retailers as of October 28, 2026, with prices from $1,021 to $5,031, a $4,009 spread on the same certified stone. Rare Carat lists it at $5,031. 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.
