This 5.1ct lab-grown marquise sits in the over five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843607242 or 843607242. Listed at 21 retailers as of October 30, 2026, with prices from $1,262 to $10,486, a $9,225 spread on the same certified stone. Brilliant Earth lists it at $10,486. 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.
