About this 1.29ct lab-grown marquise diamond

This 1.29ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG801682733 or 801682733. Listed at 14 retailers as of November 3, 2026, with prices from $318 to $1,220, a $902 spread on the same certified stone. Brilliant Earth lists it at $1,220. 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.
