About this 2.5ct lab-grown marquise diamond

This 2.5ct lab-grown marquise sits in the two to three carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG799688588 or 799688588. Listed at 2 retailers as of October 30, 2026, with prices from $1,285 to $1,700, a $415 spread on the same certified stone. The Diamond Guys lists it at $1,700. 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.
