About this 3.51ct lab-grown marquise diamond

This 3.51ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG848653630 or 848653630. Listed at 12 retailers as of October 31, 2026, with prices from $1,719 to $7,002, a $5,283 spread on the same certified stone. Taylor and Hart lists it at $7,002. 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.
