About this 1.26ct lab-grown marquise diamond

This 1.26ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840664753 or 840664753. Listed at 12 retailers as of October 28, 2026, with prices from $256 to $1,250, a $994 spread on the same certified stone. Brilliant Earth lists it at $1,250. 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.
