This 3.05ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG838644064 or 838644064. Listed at 15 retailers as of October 31, 2026, with prices from $1,289 to $5,251, a $3,963 spread on the same certified stone. Taylor and Hart lists it at $5,251. 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.
