About this 4ct lab-grown marquise diamond

This 4ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG828680375 or 828680375. Listed at 14 retailers as of October 27, 2026, with prices from $1,345 to $3,867, a $2,521 spread on the same certified stone. Rare Carat lists it at $3,867. 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.
