About this 3.51ct lab-grown marquise diamond

This 3.51ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG850679708 or 850679708. Listed at 6 retailers as of October 28, 2026, with prices from $1,351 to $5,065, a $3,715 spread on the same certified stone. Rare Carat lists it at $5,065. 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.
