About this 1.33ct lab-grown marquise diamond

This 1.33ct 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) and certified by IGI LG783605180 or 783605180. Listed at 3 retailers as of October 27, 2026, with prices from $756 to $1,000, a $244 spread on the same certified stone. The Diamond Guys lists it at $1,000. 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.
